What Lua version does this checker support?

The checker supports Lua 5.1 through 5.4 syntax, covering most common Lua implementations including LuaJIT.

Does this tool execute my Lua code?

No, this tool only checks syntax. It does not execute or run your code, so it's completely safe to use with any Lua script.

What file types can I upload?

You can upload .lua files or any text files containing Lua code. The tool will extract and validate the Lua syntax from the uploaded content.

Is there a size limit for the code I can check?

There's no hard limit, but very large files may take longer to process. For best performance, we recommend checking files under 1MB.
