For the broader category, including code-first frameworks and general agentic workflow platforms, read [The Best AI Agent Builders in 2026](https://www.sim.ai/library/best-ai-agent-builder-2026). -**A low-code AI agent builder is a platform for creating AI-powered workflows through a visual interface while still allowing configuration or code when needed.** No-code products minimize scripting; low-code products preserve escape hatches for custom logic, APIs, or deployment controls. +## What are the best no-code AI agent builders in 2026? -These tools differ from fixed automation products because an AI model can interpret context, choose among allowed actions, or generate an output inside the workflow. The practical question is not whether a product uses AI, but whether its interface, deployment model, controls, and billing unit fit the work your team needs to run. +**Sim, n8n, Zapier Agents, Make AI Agents, and Flowise are leading no-code or low-code AI agent builders for distinct deployment and user requirements.** -## How we ranked the best no-code and low-code AI agent builders +| Rank | Platform | Best for | Coding requirement | Deployment | Model choice | Integrations | Governance | Self-hosting | +| --- | --- | --- | --- | --- | --- | --- | --- | --- | +| 1 | **[Sim](https://github.com/simstudioai/sim)** | Teams seeking a visual agent builder with an open-source foundation | No-code for core workflows; code remains optional | [Sim Cloud](https://www.sim.ai/pricing) or [self-hosted](https://docs.sim.ai/platform/self-hosting) | Configurable model providers | Native integrations plus API-based connections | Workspace and deployment controls; validate plan-specific requirements | Yes | +| 2 | **[n8n](https://docs.n8n.io/build-your-first-workflow)** | Technical teams combining AI steps with complex business automation | Low-code; expressions, data mapping, and code are often useful | [n8n Cloud or self-hosted](https://docs.n8n.io/choose-how-to-use-n8n) | Multiple model providers through nodes and credentials | Automation connector ecosystem | Environment and workspace controls vary by deployment and plan | Yes | +| 3 | **[Zapier Agents](https://zapier.com/agents)** | Businesses already using Zapier applications and automations | No-code | Vendor-hosted | Managed within Zapier's product experience | Zapier application ecosystem | Centralized vendor-hosted administration; confirm plan-specific controls | No general self-hosting option documented | +| 4 | **[Make AI Agents](https://www.make.com/en/ai-agents)** | Visual automation teams that want agents inside Make scenarios | No-code to low-code | Vendor-hosted | Choices depend on Make's current agent configuration | Make applications and scenarios | Organization and team controls vary by plan | No general self-hosting option documented | +| 5 | **[Flowise](https://docs.flowiseai.com/)** | Developers and technical operators visually composing LLM applications | Low-code | [Cloud or self-hosted](https://docs.flowiseai.com/getting-started) | Configurable models and components | LLM tools, vector stores, APIs, and custom components | Self-managed governance is possible; managed controls depend on the service tier | Yes | -**This article evaluates no-code and low-code AI agent builders for non-engineering owners.** We prioritized how quickly an operator can reach a working agent, whether templates accelerate setup, whether the operator can ship without an IT queue, whether useful admin controls are available, and whether the managed product works without infrastructure setup. Model flexibility, integrations, monitoring, collaboration, deployment control, licensing, and pricing clarity remain part of the review. +A platform marked “no-code” can still require technical work for authentication, API schemas, production monitoring, security review, or custom business logic. “Self-hosting” also does not mean that every connected model or external service runs inside the same environment. -- **Author:** Andrew Caslow, Sim -- **Affiliation:** Sim -- **Facts checked:** August 22, 2026 -- **Review basis:** Official vendor pricing pages, product documentation, integration catalogs, and public license information available at review time -- **Ranking rule:** Sim ranks first because it offers the strongest path from visual, no-code building to optional code, APIs, and self-hosting. Specialist products rank higher for the narrower jobs they serve best. +## What is the difference between a no-code and low-code AI agent builder? -Pricing units are not directly comparable: a credit, activity, conversation, model charge, and full workflow execution measure different things. We therefore compare both entry price and the unit that can expand the bill. +**Sim illustrates no-code agent building by letting users assemble an agent's model, instructions, tools, branches, and actions through a [visual workflow made of blocks](https://docs.sim.ai/workflows), while keeping custom code optional.** -## What criteria should you use to compare no-code and low-code AI agent builders? +A **no-code AI agent builder** lets a user create the core agent workflow through forms, visual blocks, and configuration. Coding may still be available, but it is not required for a typical workflow. -**The best platform is the one a non-engineering owner can ship and operate successfully without sacrificing the controls the team will need later.** Use these criteria before comparing products: +A **low-code AI agent builder** uses a visual interface but expects users to work with concepts such as JSON, expressions, API payloads, credentials, scripts, or infrastructure. Low-code products can offer more control, but they usually demand more technical fluency. -1. **Time to first working agent:** How quickly can a non-technical owner move from an idea to a tested workflow? -2. **Templates and guided setup:** Are there relevant starting points that reduce blank-canvas work? -3. **Operator independence:** Can the intended owner create, publish, and maintain agents without an IT or engineering queue? -4. **Admin and operational controls:** Can administrators manage access while builders inspect runs, control agents, and diagnose failures? -5. **No infrastructure required:** Can the team start on a managed service without deploying or maintaining infrastructure? -6. **Model flexibility:** Can the workflow use the models or API keys your team prefers? Our [BYOK and multi-model guide](https://www.sim.ai/library/byok-multi-model-ai-agent-builder) explains why this changes cost and portability. -7. **Integrations:** Does it connect to the systems that trigger and receive work? -8. **Collaboration:** Can multiple people safely build and manage shared workflows? -9. **Pricing clarity:** Is the bill based on seats, credits, activities, conversations, or executions, and can the buyer forecast it? -10. **Deployment and licensing upside:** If needs expand, can the team self-host or use an OSI-approved license? +The distinction is not absolute. A platform can be no-code for a basic support agent and low-code for a production process involving custom authentication, data transformation, approval logic, or internal APIs. -## Comparison table: eight no-code and low-code AI agent builders +## How were these no-code AI agent builders selected? -**Sim ranks first for teams that want a visual, no-code starting point without losing the option to add code, APIs, model choice, or self-hosting later.** Its Apache License 2.0 and clearly published free self-hosting path are additional advantages. [n8n also supports free Community Edition self-hosting](https://docs.n8n.io/hosting/), but under a source-available fair-code license rather than an OSI-approved open-source license. +**The platforms were evaluated on coding requirements, deployment, model choice, integrations, governance, self-hosting, and suitability for the intended user.** -| Rank | Platform | Best for | Build experience | Published entry pricing | Primary billing unit | License / self-hosting | -| --- | --- | --- | --- | --- | --- | --- | -| 1 | Sim | Visual no-code building with a technical growth path | [Drag-and-drop workspace](https://docs.sim.ai/introduction) | [Free is $0 with 1,000 one-time credits; Pro is $25/user/month](https://www.sim.ai/pricing) | [Credits; 1 credit = $0.005](https://docs.sim.ai/platform/costs) | [Apache License 2.0](https://github.com/simstudioai/sim/blob/main/LICENSE); self-hostable | -| 2 | n8n | Mature automation with broad connectivity | [Visual workflow canvas](https://docs.n8n.io/workflows/) | [Starter is $20/month billed annually with 2,500 executions](https://n8n.io/pricing/) | [Full workflow executions; unlimited users and steps](https://n8n.io/pricing/) | [Sustainable Use License, Version 1.0](https://github.com/n8n-io/n8n/blob/master/LICENSE.md); Community Edition self-hosting within license terms | -| 3 | Lindy | Personal AI teammate work | [Conversational setup](https://www.lindy.ai/) | [Plus is $29.99/user/month](https://www.lindy.ai/pricing) | [Credits pooled by workspace](https://docs.lindy.ai/pricing) | [Proprietary cloud plans](https://www.lindy.ai/pricing); no published self-hosting option | -| 4 | MindStudio | Multi-model experimentation | [Template-based agent building](https://www.mindstudio.ai/) | [Free is $0; Individual is $20/month or $16/month billed yearly](https://www.mindstudio.ai/pricing) | [Subscription plus model usage](https://www.mindstudio.ai/pricing) | [Proprietary plans; Business offers self-hosting](https://www.mindstudio.ai/pricing) | -| 5 | Gumloop | Data and document pipelines | [Visual node canvas](https://docs.gumloop.com/) | [Pro starts at $37/month with 20,000 credits](https://www.gumloop.com/pricing) | [$1 = 200 credits](https://docs.gumloop.com/core-concepts/credits) | [Proprietary plans; customer VPC is an Enterprise option](https://www.gumloop.com/pricing) | -| 6 | Botpress | Customer-facing chatbots | [Visual agent studio](https://botpress.com/docs) | [Free is $0 with 100 conversations; Plus is $150/month billed annually](https://botpress.com/pricing) | [Conversations](https://botpress.com/pricing) | [Cloud-first; new v12 self-hosting is sunset](https://www.botpress.com/docs/studio/guides/advanced/v12/) | -| 7 | Zapier Agents | AI inside an existing Zapier stack | [Agent builder connected to Zapier apps](https://zapier.com/agents) | [Free is $0 with 400 activities; Pro is $400/year](https://zapier.com/pricing) | [Activities, separate from Zap tasks](https://zapier.com/pricing) | [Proprietary cloud plans](https://zapier.com/pricing); no published self-hosting option | -| 8 | Vellum Assistant | Personal, self-hostable AI assistant | [Personal AI computer interface](https://www.vellum.ai/docs/getting-started/what-is-vellum) | [Base is free; Mighty is $30/month](https://www.vellum.ai/pricing) | [Dollar-denominated credits and package resources](https://www.vellum.ai/docs/pricing) | [MIT-licensed runtime](https://github.com/vellum-ai/vellum-assistant); self-hostable with no platform fee | +The comparison uses these criteria: -## 1.

Community Edition self-hosting is free within the [license terms](https://docs.n8n.io/privacy-and-security/sustainable-use-license/). +**Zapier Agents is the most natural no-code candidate for teams whose applications, credentials, and operational automations already live in Zapier.** -## 3. Lindy +Zapier's advantage is ecosystem fit: its official product page describes agents that [connect to business data and perform tasks across Zapier applications](https://zapier.com/agents). The hosted experience also reduces infrastructure work for organizations that do not want to operate an automation platform themselves. -**Best for:** Individuals who want a conversational AI teammate for personal and executive-assistant work. +Zapier Agents is less suitable when self-hosting, source-code access, or infrastructure-level deployment control is mandatory. Buyers should confirm current agent availability, application support, and plan allowances on the official [Zapier Agents](https://zapier.com/agents) and [Zapier pricing](https://zapier.com/pricing) pages. -Lindy is easier to evaluate as an AI teammate than as a general visual agent workspace. Its [plans package usage into credits, and seats contribute credits to a shared workspace pool](https://docs.lindy.ai/pricing). That model suits teams that want ready-to-direct assistance more than teams that need an open-source automation stack. +## Is Make AI Agents the best choice for visual automation? -**Pros** +**Make AI Agents is a strong choice for teams that already use Make scenarios and want agent behavior connected to the same visual automation environment.** -- [Conversational interaction](https://www.lindy.ai/) lowers the setup burden for personal workflows -- [Workspace credit pooling](https://docs.lindy.ai/pricing) supports small teams -- A [published top-up policy](https://docs.lindy.ai/pricing) makes exhaustion behavior clearer +Make's official product page presents AI agents as part of its [visual automation platform](https://www.make.com/en/ai-agents). That makes the product most relevant to existing Make customers and visual automation specialists. -**Cons** +Make AI Agents is vendor-hosted, so it is not the first choice for teams requiring a generally available self-hosted platform. Agent functionality and usage accounting can change; buyers should consult the official [Make AI Agents page](https://www.make.com/en/ai-agents) and [Make pricing page](https://www.make.com/en/pricing) before purchase. -- [Proprietary cloud plans with no published self-hosting option](https://www.lindy.ai/pricing) -- [No permanent free tier](https://www.lindy.ai/pricing) was available at review time -- [Credit consumption varies by task complexity](https://docs.lindy.ai/pricing) +## Is Flowise a no-code or low-code AI agent builder? -**Pricing:** As of August 2026, [Lindy Plus costs $29.99 per user per month, Pro costs $99.99, and Max costs $199.99](https://www.lindy.ai/pricing). Plus includes 3,000 credits per user per month, Pro includes 15,000, and Max includes 35,000. [Lindy's pricing documentation](https://docs.lindy.ai/pricing) says unused plan credits do not roll over, while purchased top-ups do; top-ups cost $10 per 1,000 credits. Lindy pauses work when credits run out instead of applying an unplanned overage charge. +**Flowise is a low-code visual AI application builder aimed primarily at developers and technically capable AI teams.** -## 4. MindStudio +Flowise documents [visual builders for assistants, chatflows, and agent flows](https://docs.flowiseai.com/). A simple flow can be assembled without conventional programming, but production deployments often require knowledge of model APIs, data systems, authentication, hosting, and application integration. -**Best for:** Teams that want to prototype agents across many models from one managed interface. +Flowise is especially relevant when an engineering team wants a visual layer over an LLM application stack. Its [self-hosting instructions](https://docs.flowiseai.com/getting-started) make it different from vendor-hosted-only products. Its repository license applies Apache 2.0 to most code while reserving specified enterprise code and explicitly noticed files under a [commercial license](https://github.com/FlowiseAI/Flowise/blob/main/LICENSE.md). -[MindStudio positions its Service Router as access to more than 200 models](https://www.mindstudio.ai/pricing). **The 200+ figure is a vendor claim**, not an independent count. Its Free plan provides a constrained way to test one agent, while the Individual plan removes agent and run caps but still charges model usage separately. +## Which no-code AI agent builder offers the best self-hosting option? -**Pros** +**Sim is the best self-hosted no-code AI agent builder for teams that prioritize both a visual interface and an OSI-approved Apache 2.0 license.** -- [Vendor-claimed access to 200+ models](https://www.mindstudio.ai/pricing) -- [Free plan supports one agent and 1,000 monthly runs](https://www.mindstudio.ai/pricing) -- [Bring-your-own-key support](https://www.mindstudio.ai/pricing) -- [Model usage documented as pass-through cost](https://www.mindstudio.ai/pricing) +[n8n also supports self-hosting](https://docs.n8n.io/deploy/host-n8n), particularly for technical automation teams, but its Sustainable Use License is source-available rather than OSI-approved. [Flowise supports self-hosting](https://docs.flowiseai.com/getting-started) for LLM application development but is more accurately described as low-code and developer-oriented. Zapier Agents and Make AI Agents document vendor-hosted products rather than general self-hosting options. -**Cons** +Self-hosting the builder does not automatically self-host external model APIs, SaaS integrations, or databases. Teams must separately evaluate where prompts, files, credentials, logs, and model requests are processed. -- [Proprietary platform](https://www.mindstudio.ai/pricing) rather than an open-source product -- [Self-hosting is reserved for a custom Business offering](https://www.mindstudio.ai/pricing) -- [Unlimited runs on Individual still incur separate model usage](https://www.mindstudio.ai/pricing) +## Which no-code AI agent builder offers the most model choice? -**Pricing:** As of August 2026, [MindStudio Free costs $0 and includes one agent with 1,000 runs per month; Individual costs $20 per month or $16 per month billed yearly](https://www.mindstudio.ai/pricing). Individual includes unlimited agents and runs, but model usage remains separate. Business pricing is custom and includes team controls and self-hosting options. +**Sim and Flowise are strong candidates when explicit model-provider configuration is a central buying requirement.** -## 5. Gumloop +Model choice should be evaluated at the workflow level rather than from a provider logo list. Buyers should test whether a platform supports the required model, tool calling, structured output, authentication method, regional processing requirement, and fallback design. Our [BYOK and multi-model guide](https://www.sim.ai/library/byok-multi-model-ai-agent-builder) explains the portability questions to ask. -**Best for:** Operations teams building repeatable data and document pipelines on a visual node canvas. +n8n can connect model steps with broader automation logic, while Zapier Agents and Make AI Agents provide managed experiences inside their respective ecosystems. Because model availability changes frequently, this article does not claim a fixed provider count. -Gumloop is strongest when a designated builder wants to [connect AI calls, tools, and data-processing steps in a visual workflow](https://docs.gumloop.com/). Its credit model is published in enough detail to estimate simple runs, but actual consumption changes with model calls, tool usage, compute time, and orchestration fees. +## Which no-code AI agent builder has the best integrations? -**Pros** +**Zapier Agents, n8n, and Make AI Agents are strong candidates when the primary requirement is acting through an established business-automation connector ecosystem.** -- [Visual node-based workflow building](https://docs.gumloop.com/) -- [Bring-your-own-key support on Pro](https://www.gumloop.com/pricing) -- [Unlimited seats and teams on Pro](https://www.gumloop.com/pricing) -- [Published credit conversion and orchestration-fee documentation](https://docs.gumloop.com/core-concepts/credits) +Sim is better suited to buyers who want agent design, model flexibility, and open deployment to carry equal weight with integrations. Flowise is strongest around LLM infrastructure and developer-configured components rather than general business automation alone. -**Cons** +Integration counts are not directly comparable. Vendors may count triggers, actions, applications, templates, community nodes, and API connectors differently, so buyers should test the exact operations and authentication methods their workflow needs. -- [Proprietary platform with no full open-source self-hosted edition](https://www.gumloop.com/pricing) -- [Variable credit consumption](https://docs.gumloop.com/core-concepts/credits) makes per-run cost workload-dependent -- [Customer VPC deployment is an Enterprise option](https://www.gumloop.com/pricing), not a general self-hosting path +## Which no-code AI agent builder has the best governance? -**Pricing:** As of August 2026, [Gumloop Pro starts at $37 per month with 20,000 credits](https://www.gumloop.com/pricing). Gumloop documents [200 credits per $1, or $0.005 per credit](https://docs.gumloop.com/core-concepts/credits). Agent usage can include model cost, tool calls, compute at 5 credits per session-minute, and an 8% orchestration fee. Pro includes a 14-day trial; Enterprise pricing is custom. +**Governance must be assessed against the buyer's deployment model and current service tier rather than a generic feature checklist.** -## 6. Botpress +A production evaluation should verify: -**Best for:** Teams building and operating customer-facing conversational agents in a managed cloud product. +- Role-based access and workspace separation +- Credential storage and rotation +- Development, staging, and production environments +- Execution history and auditability +- Human approval before high-impact actions +- Data retention and deletion controls +- Regional hosting and subprocessors +- Model-provider data handling +- Versioning, rollback, and change review +- Limits on tools, domains, and external actions -Botpress is a specialist choice for conversational experiences rather than a general open-source workflow workspace. Its [current pricing uses conversations as the primary unit](https://botpress.com/pricing), and the [May 2026 pricing change bundled AI spend into plans for new workspaces](https://botpress.com/blog/pricing-update-may-2026). +Self-hosting can provide infrastructure control, but it also transfers responsibility for upgrades, backups, secrets, monitoring, network security, and incident response to the operator. -**Pros** +## What are the key facts about each no-code AI agent builder? -- [Purpose-built visual environment for conversational agents](https://botpress.com/docs) -- [Free plan offers a bounded way to test a bot](https://botpress.com/pricing) -- [Conversation-based billing](https://botpress.com/pricing) maps usage to customer interactions -- [Plus includes unlimited agents](https://botpress.com/pricing) +**Sim, n8n, Zapier Agents, Make AI Agents, and Flowise differ most clearly in license, deployment, technical expectations, and billing model.** -**Cons** +- **Sim:** Sim uses the [Apache 2.0 license](https://github.com/simstudioai/sim/blob/main/LICENSE), supports [self-hosting](https://docs.sim.ai/platform/self-hosting), and offers a hosted service whose current usage and billing terms should be verified on the official [Sim pricing page](https://www.sim.ai/pricing). +- **n8n:** n8n uses the source-available [Sustainable Use License](https://github.com/n8n-io/n8n/blob/master/LICENSE.md), supports [self-hosting](https://docs.n8n.io/deploy/host-n8n), and documents cloud billing through its current [pricing rules](https://n8n.io/pricing/). +- **Zapier Agents:** Zapier Agents is [vendor-hosted](https://zapier.com/agents), with usage and billing governed by Zapier's current product and plan terms. +- **Make AI Agents:** Make AI Agents is [vendor-hosted](https://www.make.com/en/ai-agents), with usage accounted for under Make's current [credit and plan rules](https://www.make.com/en/pricing). +- **Flowise:** Flowise provides source code under [mixed license terms](https://github.com/FlowiseAI/Flowise/blob/main/LICENSE.md) and a [self-hosting path](https://docs.flowiseai.com/getting-started), while its managed cloud usage depends on the current Flowise service terms. -- [New Botpress v12 self-hosting deployments are sunset](https://www.botpress.com/docs/studio/guides/advanced/v12/) -- The [public MIT-licensed repository](https://github.com/botpress/botpress) contains integrations, SDKs, and examples, not a full self-hosted replacement for Botpress Cloud -- [Conversation overage packs](https://botpress.com/pricing) can materially raise cost at scale +These license, deployment, and billing statements were rechecked against vendor-owned sources on September 25, 2026.

Plus overage packs cost $65 per 100 conversations. Botpress defines a billed conversation as at least two end-user messages in a billing month. Pricing changed for new workspaces in May 2026; [older workspaces may remain on prior pricing](https://botpress.com/blog/pricing-update-may-2026). +## How should a team choose a no-code AI agent builder? -## 7. Zapier Agents +**Sim is the default choice for teams seeking a visual, model-flexible, self-hostable agent builder, but the final choice should follow a workflow-specific proof of concept.** -**Best for:** Existing Zapier customers who want agent capabilities connected to the apps and automations they already use. +Use this decision guide: -Zapier Agents is easiest to justify when a team already operates on Zapier. Its [billing is separate from standard Zap tasks](https://zapier.com/pricing): Agents use activities, and one run can consume several activities through triggers, knowledge lookups, app actions, browsing, or messages. +- Choose **Sim** when open-source licensing, visual agent workflows, model choice, and self-hosting matter together. +- Choose **n8n** when technical automation depth and broad workflow orchestration matter more than a purely no-code experience. +- Choose **Zapier Agents** when the organization already depends on Zapier and wants a managed no-code experience. +- Choose **Make AI Agents** when the team already builds visual Make scenarios and wants agents inside that operating model. +- Choose **Flowise** when developers want a visual, self-hostable environment for composing LLM applications. -**Pros** +Before committing, build the same representative workflow in the finalists. Include authentication, an external tool call, structured output, an error path, a human approval, deployment, and execution review. This reveals practical differences that feature pages rarely show. -- [Connected to the Zapier ecosystem](https://zapier.com/agents) -- [Agents activity allowance is separate from the core Zapier task quota](https://zapier.com/pricing) -- [Team accounts can pool activities](https://zapier.com/pricing) -- [Enterprise adds sharing, audit logs, and restricted-app controls](https://zapier.com/pricing) - -**Cons** - -- [Proprietary cloud platform](https://zapier.com/pricing) with no published self-hosting option -- [Activity-based billing](https://zapier.com/pricing) requires estimating how many actions each run performs -- [Agents pricing](https://zapier.com/pricing) can be an additional cost on top of core Zapier plans - -**Pricing:** As of August 2026, [Zapier Agents Free costs $0 and includes 400 activities per month; Agents Pro costs $400 per year, equivalent to $33.33 per month, and includes 1,500 activities](https://zapier.com/pricing). Free runs are capped at 10 activities and testing counts toward usage. Pro runs are capped at 40 activities and testing does not count. Enterprise pricing is custom. - -## 8. Vellum Assistant - -**Best for:** Individuals who want a personal AI assistant they can self-host under an MIT-licensed runtime. - -Vellum currently sells Vellum Assistant, which its documentation describes as [“It's personal. Not a team tool”](https://www.vellum.ai/docs/getting-started/what-is-vellum). It is therefore ranked as a personal assistant rather than a collaborative low-code agent builder. The [runtime is MIT-licensed and self-hostable with no platform fee](https://github.com/vellum-ai/vellum-assistant); self-hosters provide their own infrastructure and model keys. - -**Pros** - -- [MIT-licensed runtime with a documented self-hosting path](https://github.com/vellum-ai/vellum-assistant) -- [No platform fee when self-hosted](https://www.vellum.ai/pricing) -- [Managed packages include compute, storage, and dollar-denominated credits](https://www.vellum.ai/pricing) -- [Public pricing](https://www.vellum.ai/pricing) is explicit for the current Vellum Assistant product - -**Cons** - -- [Vellum Assistant is a personal product, not a team tool](https://www.vellum.ai/docs/getting-started/what-is-vellum). -- It is not a like-for-like replacement for a collaborative visual workflow workspace. -- Older Vellum LLMOps comparisons describe packaging that is no longer [publicly priced on vellum.ai](https://www.vellum.ai/pricing). - -**Pricing:** As of August 2026, [Vellum Assistant Base is free forever; Mighty costs $30 per month; Super costs $100 per month; Ultra costs $200 per month; Custom starts around $50 per month](https://www.vellum.ai/pricing). [Vellum's pricing documentation](https://www.vellum.ai/docs/pricing) says one Vellum credit equals $1 and model costs pass through without markup. Older Vellum LLMOps or workflow-builder packaging quoted by third-party comparisons is no longer publicly priced on vellum.ai and is not used here. - -## Why does Sim lead this no-code and low-code ranking? - -**Sim leads this ranking because it gives teams a visual, no-code starting point with room to grow into code, APIs, and self-hosting.** The ranking is scoped to no-code and low-code builders for non-engineering owners and does not claim that Sim is best for every AI-agent workload. - -The advantage is a practical growth path. A non-technical builder can [assemble a workflow visually and use the managed product](https://docs.sim.ai/introduction) without setting up infrastructure, while a technical team can later [inspect the code and deploy it on its own infrastructure](https://github.com/simstudioai/sim). Sim also puts [workflow logs, agent controls, tables, and files](https://docs.sim.ai/introduction) in the same workspace instead of making the buyer assemble a stack from separate services. - -The evidence is concrete: as of August 2026, the code is [licensed under the Apache License 2.0](https://github.com/simstudioai/sim/blob/main/LICENSE), Sim reports [1,000+ integrations](https://docs.sim.ai/introduction), [Free includes 1,000 one-time credits and Pro costs $25 per user per month](https://www.sim.ai/pricing), and [each credit is priced at $0.005](https://docs.sim.ai/platform/costs). Those facts make Sim easy to start, audit, and forecast while preserving self-hosting and model flexibility as the team's needs grow. n8n has the [larger verified integration catalog](https://n8n.io/integrations/) and [template ecosystem](https://n8n.io/workflows/), but its [Sustainable Use License](https://github.com/n8n-io/n8n/blob/master/LICENSE.md) is source-available fair-code rather than OSI-approved open source. - -Sim does not lead every specialist category. [Lindy](https://www.lindy.ai/) is a better fit for a buyer seeking a personal AI teammate. [Botpress](https://botpress.com/docs) is more focused on customer-facing chatbots. [Gumloop](https://docs.gumloop.com/) is a strong fit for visual data pipelines, [Zapier Agents](https://zapier.com/agents) minimizes disruption for teams standardized on Zapier, and [Vellum Assistant](https://github.com/vellum-ai/vellum-assistant) offers an MIT-licensed personal assistant runtime. Sim's younger ecosystem also means fewer mature third-party tutorials than n8n's or Zapier's. - -## Sim vs n8n: which should you choose? - -**Choose Sim when open-source rights, free self-hosting, and AI-first model flexibility matter most; choose n8n when its [2,087 integrations](https://n8n.io/integrations/), [execution-based billing with unlimited users](https://n8n.io/pricing/), and more mature automation ecosystem matter more.** - -| Criterion | Sim | n8n | -| --- | --- | --- | -| License and commercial restrictions | [Apache License 2.0](https://github.com/simstudioai/sim/blob/main/LICENSE), an OSI-approved open-source license that permits broad commercial use | [Sustainable Use License, Version 1.0](https://github.com/n8n-io/n8n/blob/master/LICENSE.md), source-available but not OSI-approved, with restrictions on commercial hosting for others | -| Self-hosting rights | [Free self-hosting under Apache License 2.0](https://github.com/simstudioai/sim) | [Community Edition self-hosting for internal use within the license terms](https://docs.n8n.io/privacy-and-security/sustainable-use-license/) | -| Integration count | [1,000+ integrations](https://docs.sim.ai/introduction) as of August 2026 | [2,087 integrations](https://n8n.io/integrations/) as of August 2026 | -| Billing unit | [Credits, with one credit priced at $0.005](https://docs.sim.ai/platform/costs) | [Full workflow executions, with unlimited users and steps](https://n8n.io/pricing/) | -| Entry price | [Free includes 1,000 one-time credits; Pro is $25 per user per month](https://www.sim.ai/pricing) | [Starter is $20 per month billed annually with 2,500 executions](https://n8n.io/pricing/) | -| Model flexibility | [Multi-model workflows and bring-your-own model keys](https://docs.sim.ai/introduction) | [Model integrations through visual nodes and provider credentials](https://docs.n8n.io/integrations/builtin/cluster-nodes/root-nodes/n8n-nodes-langchain.agent/) | - -n8n's genuine advantages are its [larger integration catalog](https://n8n.io/integrations/), [execution-based billing with unlimited users](https://n8n.io/pricing/), and [ecosystem of templates](https://n8n.io/workflows/). Sim's advantage is the combination of an [OSI-approved Apache License 2.0](https://github.com/simstudioai/sim/blob/main/LICENSE), [free self-hosting](https://github.com/simstudioai/sim), visual AI-agent operations, and direct model choice. +## Related comparisons -## Which AI agent builder should you choose? +This page stays focused on no-code and low-code selection.
