html-video

html-video is a devtool that lets coding agents programmatically convert HTML, CSS, and data into real MP4 videos on a laptop, using pluggable render engines and 21 templates with AI soundtrack support. It’s built for developers and AI agents who need to generate dynamic, customizable videos without per-render fees or cloud dependencies. Its open-source, Apache-2.0 license and offline capability make it uniquely interesting for automating video production in local development workflows.
