## What it is
html-video is a programmatic HTML-to-video tool that lets coding agents turn HTML, CSS, and data into real MP4 files locally using pluggable render engines (headless Chromium + ffmpeg), 21 templates, and optional AI soundtracks. It is an Apache-2.0 open-source project by the Open Design team with no per-render fees or vendor lock-in.

## Use cases
- turn html css into mp4 video programmatically
- generate videos from article links or github repos with a coding agent
- render animated data visualizations as video locally
- create programmatic video without cloud render fees
- convert markdown content into animated explainer videos
- use claude code or cursor to produce videos from prompts

## When to choose
- you want local, fee-free video rendering with no vendor lock-in
- you already use a coding agent and want video as an output format
- you need pluggable render engines and reusable HTML video templates
- you prefer open-source Apache-2.0 tooling

## When to avoid
- you need a fully managed cloud video rendering service
- you want a GUI-based video editor rather than agent/code-driven workflows
- you need real-time video streaming or live editing
- you cannot run Node.js 24 and headless Chromium locally
