Write HTML. Render video. Built for agents. An open-source framework that turns HTML, CSS, media, and animations into deterministic MP4 videos. Agents write plain HTML compositions and a non-interactive CLI renders them to video; install it into coding agents like Claude Code with npx skills add. Built by HeyGen, licensed Apache-2.0.
CC Workflow Studio
Design workflows on a canvas in VS Code and export them as Markdown your AI agent already understands — skills, commands, and agents for Claude Code, Cursor, Copilot, and more. An MCP server runs in the background so you can refine workflows in natural language with 'Edit with AI'.
