HyperFrames
Code-based video renderer · Video
HeyGen's open-source framework that turns an HTML page with timed animations into an MP4. Claude writes each scene as a web page and renders it; a change edits one line and re-renders.
Use it for
Motion-graphics explainers and product films when the scenes are closer to web pages than to video, especially reusing a site's own HTML and CSS.
Choose something else for
Not a generative video model and not a timeline editor. Not needed for the family video, which already runs on Remotion.
Give it
HTML, CSS and JavaScript scenes; Images; Video; Audio
Get back
Rendered MP4 video
How it is operated
Command-line tool plus a browser studio; renders with headless Chrome and FFmpeg on your own machine.

Assemble, convert and export
★★★★☆ 4/5 for this task
Same job as Remotion with a plainer format: HTML instead of React, a friendlier Apache-2.0 licence and no company-size limit. Below Remotion only because Remotion is proven in delivered Studio work and HyperFrames is not.
Decision: Try it on one motion-graphics film built from an existing web page. Keep Remotion for the family video.
Limits and things to check
- Needs Node.js, headless Chrome and FFmpeg.
- Studio has not rendered a test with it yet.
- Released March 2026 and changing fast: pin a version for a project.
Rival to Remotion. Same promise: every frame is exact and a change is a re-render, not a restart. Licence is simpler than Remotion's, which is free only up to three employees for companies.
