Description

A library mod that lets other mods compile and run sandboxed Luau scripts. Native Luau libraries are bundled inside the mod JAR, so no native code is downloaded at runtime.

Features

  • Strict type checking and compilation of in-memory Luau source files.
  • Isolated, persistent ScriptInstances with explicit lifecycle management.
  • Controlled source and host modules, including a sandboxed require.
  • Safe conversion between Java values and Luau values.
  • Limits for execution time, interrupt checks, VM memory, and host calls.
  • Source breakpoints, stepping, pause, resume, and termination support.
