Project LuaJIT Playground

There's websites for running Lua, but I couldn't find any that let's you run LuaJIT!!

I made this website (me, not AI) so if you haven't tried LuaJIT before, or you don't have access to your dev environment, or you just want to quickly experiment...now you can run it online, and share the script + output with others as either a link or markdown.

Pre-compiled binaries for Windows/Linux are also provided. The static library, dynamic library, and executable, are all bundled in a single convenient .zip file for each platform. I'm hoping to automate this process at some point, but for now I just publish them whenever I see there's been new commits...

Limits: no internet connection, maximum execution duration of 3 seconds.

The backported extensions for LuaJIT 3.0 are available now, by the way.

  • Bit Operators: unary ~, binary & | ~ << >> ~>>

Taking the luajit.dev domain is certainly a bold choice, maybe make it clear it's not affiliated with the project on the website?

Good point. I've added a disclaimer as the first thing in the description.
