I’ve developed a suite of tools to help me make games and art. Most of them started as something I needed for my own work and got released once it turned out other people needed it too. They are all free and open source, and they tend to share the same approach: small, fast, dependency free, and simple enough to understand all the way down.

A few have found real audiences. LittleJS has over 4,000 stars on GitHub and ZzFX makes sound in thousands of web games. Here are the best ones I’ve made to share with the community. Let me know if you use them, I’d love to hear about it!
