HyperFrames
Open-source framework for turning HTML, CSS, media and seekable animations into deterministic MP4 videos for local CLI use, AI coding agents and hosted workflows.
HyperFrames lets developers and AI coding agents define videos as HTML and render them deterministically to MP4. It supports HTML, CSS, media and seekable animations, with workflows for product videos, explainers, slideshows, motion graphics, site tours and other compositions. The CLI can initialize a project, preview it in a browser, lint and check the composition, and render the result. The project also provides skills that agents can load on demand and a catalog of reusable blocks and components. The official documentation lists Node.js 22+ and FFmpeg as requirements. The repository is Apache 2.0 licensed. It is a developer-focused rendering framework, so using it requires a Node.js/FFmpeg environment and familiarity with HTML or the available agent skills.
