Hi! Thanks for starting this thread.

I’m Lee. I initiated L5 this fall/winter. [L5](https://l5lua.org) is a Lua-based creative coding library that should feel like home to those coming from p5.js or Processing. L5 is only 6MB, works on older computers and is lightning-fast on recent ones. It’s built on top the software framework Love2d, and was designed with concepts of [permacomputing](https://permacomputing.net/) in mind.

L5 is cross-platform, and already has a lot of tutorials, a full reference, and some new approaches to documentation. For example,you can [download the website](https://l5lua.org/download/#offline-documentation) for offline use, and the site has been designed to be fast and lightweight to run on lower-bandwidth connections.

L5 is new and currently in alpha. It still has bugs and is not at feature parity with Processing or p5 yet. There is an article [L5 for Processing and p5.js programmers](https://l5lua.org/L5-for-processingp5/) that members of this forum might be interested in. And there are opportunities for [contributing](https://l5lua.org/contributing/) to the L5 library as well as its documentation.

I’m looking forward to ongoing work with L5, and to see what community-members create.
