HyperFrames renders HTML and CSS into deterministic MP4 video from a local CLI, with agent skills so a coding agent can generate video variants from code.

Open-source video-as-code framework from HeyGen (Apache-2.0, TypeScript): write HTML, CSS and seekable animations, render a deterministic MP4. No timeline editor. Runs locally via a CLI (Node 22+ and FFmpeg) with an init/lint/preview/render/publish loop, ships 20 agent skills so Claude Code, Cursor or Gemini CLI can drive it, and can generate hundreds of variants from code. Optional HeyGen-hosted cloud and AWS Lambda rendering sit on top of the open core.
Short-form and variant-heavy video is a distribution problem, and the usual tools price it per seat or per render. HyperFrames turns a video into a file of HTML you can diff, version in git, and template. The GTM payoff is variants at zero marginal cost: one composition, a data file, and the localized demo or the fifty ad cuts render themselves. Because it ships as agent skills, the render step becomes something an agent calls inside a content pipeline rather than a person in an editor. The honest read: it is open-core, so anything past local rendering leans on HeyGen's paid cloud, and video-as-code moves the work from editing to authoring good HTML, which is a different skill your team has to actually have.
