heygen-com/hyperframes
Write HTML. Render video. Built for agents.
What it is
HyperFrames is a free, open-source framework for turning HTML, CSS, media, and seekable animations into deterministic MP4 videos. Use it locally with the CLI, from AI coding agents with skills, or as the rendering core behind hosted authoring workflows. The HyperFrames Studio app is free to use as well; its Pro plan adds HeyGen's top video, image, voice and music models.
When to use it
Reach for hyperframes when you want an LLM to plan, call tools, browse, or coordinate with other agents instead of answering a single prompt — it's written in TypeScript and fits stacks tagged ai, ai-agents, animation, claude-code.
