We just open-sourced Cetus — render HTML to video with a single binary.

Been building this quietly for a while. Shipping it today.

Cetus is an HTML-to-video renderer — write HTML with CSS animations, GSAP, Three.js, WebGL, whatever. Cetus captures every frame with a bundled headless Chrome and pipes it through bundled ffmpeg. One binary, fully self-contained.

Would love feedback, bug reports, and honest opinions. What would make this actually useful for your workflow?
