- https://luau-lang.org (Lua derivative, interpreted / sandboxed, from Roblox)
- https://terralang.org (Lua JIT compiler)
- https://nelua.io (Lua-syntax -> C compiler (WASM too w/ Emscripten)
- https://github.com/pallene-lang/pallene (Lua AOT compiler)
- https://github.com/teal-language/tl (Teal -> Lua compiler)
- https://typescripttolua.github.io/ (TS -> Lua compiler)

With minimum effort you can get a lot of benefit from using Sumneko's Lua language server in VSCode for near many Lua versions (LuaJIT, PUC-Rio Lua, etc.)
All of the projects serve different purposes, whether you need/love Lua for speed (JIT, for games), low memory usage (AOT, for embedded), or simplicity (all of them).
