About HyperFrames

HyperFrames turns HTML, CSS, media and seekable animations into deterministic MP4 videos, and is built for use by AI coding agents as well as direct local CLI use. It underpins hosted authoring workflows but can also be run entirely on your own machine.

Strengths

  • Deterministic rendering makes output reproducible for automated pipelines
  • Usable directly from AI coding agents via provided skills

Limitations

  • Requires writing HTML and CSS rather than offering a visual editor
  • Distinct from HeyGen's main paid avatar video product
