An agent-focused framework that turns HTML, CSS, and animations into deterministic MP4 videos
HeyGen’s open-source tool turns HTML, CSS, media, and animations that can be scrubbed back and forth on a timeline into deterministic MP4 videos. The CLI, render engine, roughly 450 catalog blocks, and seven agent skills come together in a single production workflow. Its HTML-first approach eliminates the need for React or a build step while delivering frame-accurate rendering; with more than 6,500 commits, it’s highly mature.
Product demos, social media videos, data visualizations, and repeatable marketing clips made with code; teams that want versionable video source instead of timeline software.
Requires Node.js 22+, FFmpeg, and headless Chrome. Approve network and cost limits before enabling AWS Lambda or external media downloads.
