Hyperframes is an open-source video rendering framework that lets you create, preview, and render HTML-based video compositions - with first-class support for AI agents.
Hyperframes is inspired by Remotion.- we used Remotion at HeyGen in production, learned a ton from it, and kept attribution comments in the source for the patterns it pioneered (Chrome launch flags, image2pipe → FFmpeg streaming, frame buffering). Both tools drive headless Chrome and both are deterministic. They differ on one decision: what the primary author writes. Remotion's bet is React components; Hyperframes' bet is HTML.
