Wereweasel is the business entity behind Ennuicastr, a sole proprietorship run by Yahweasel (who does not use his real identity online for privacy reasons). Ennuicastr is the only per-se product by Wereweasel at the moment, and is open source.

In addition to Ennuicastr, Yahweasel is the author of several infrastructure libraries relating to web multimedia. In particular:

• libav.js is a port of the libav libraries from FFmpeg to JavaScript and WebAssembly. It was originally developed for Yahweasel's own use, but has since been sponsored by Descript and Riverside.
• libavjs-webcodecs-polyfill and libavjs-webcodecs-bridge connect libav.js to the WebCodecs API.
• RTEnnui is a replacement for the multimedia side of WebRTC.
• Weasound, made for RTEnnui, supports portable PCM audio in the browser.

There's also some various/miscellaneous software that Yahweasel has authored:

• Contraptcha, an AI-generated art and word puzzle game.
• nodejs-server-pages, PHP-style templating for Node.
• yalap.js, a port of libarchive to the web.
• Dung Cart, a mapper for those awful pseudo-3D dungeon crawling games.
• Craig, a voice recording bot for Discord. Note that Yahweasel was the original author, but Craig has since been passed to other maintainers.
• Whatever else is kicking around my GitHub profile or the Ennuicastr GitHub profile.

Yahweasel is also a collector of weird, obscure games, and streams them and makes YouTube videos of them. People who know Yahweasel from YouTube probably have no idea that the developer aspect of Yahweasel exists, and people who know Yahweasel as a developer have no idea that the YouTube side of Yahweasel exists!
