✦ Mods

A mod is a folder with a mod.json: FastFlags and files to replace (for example the cursor). Mods never run code.

{
  "id": "my-mod",
  "name": "My Mod",
  "description": "Turns shadows off.",
  "version": "1.0.0",
  "flags": { "FIntRenderShadowIntensity": 0 }
}

📖 Full guide: docs/MODS.md · it is also shown at the bottom of the Mods tab. To publish a mod, add it to mods/catalog.json and open a pull request.

✦ FAQ

Do I need administrator rights?

No. The installer puts Flortrap in your own folder.

Is this the official Roblox launcher?

No. Flortrap is independent and not affiliated with Roblox Corporation. Use the settings at your own risk: Roblox can change its rules and ignore some FastFlags.

Are mods safe?

Mods are data only (flags and assets). Executables and scripts are never unpacked, and replacement paths are limited to Roblox content folders.

What if I run into a problem?

✦ Build from source

Requires Windows. The .NET 8 SDK is downloaded automatically if missing.

git clone https://github.com/slenderhold/Flortrap
cd Flortrap
build-installer.bat
:: result: dist\Flortrap-Setup.exe

Keep the version in Flortrap\Flortrap.csproj and Flortrap.Setup\Flortrap.Setup.csproj equal, and tag releases with a higher number than the installed build so auto-update sees them.
