Remotion

Remotion lets you make videos with React components instead of After Effects timelines. Write JSX, use CSS animations, pull in data from APIs, render frames to MP4. Programmatic video that scales — think personalized demos, automated social clips, or data visualization videos.

If you need to generate videos from code — product demos, social media content, personalized onboarding videos — nothing else comes close in the React ecosystem. FFmpeg is the low-level workhorse but has no component model. Motion Canvas is a newer alternative for animated explainers. Editframe was a commercial API but shut down.

Best for developers who already know React and need to generate videos programmatically. The composition model (scenes, sequences, transitions) maps perfectly to component thinking.

The catch: the license requires a company license for companies with 3+ employees (free for individuals and small teams). Rendering is CPU-intensive — a 60-second video can take minutes. Cloud rendering (Remotion Lambda) works but costs AWS money. And the learning curve is "React" plus "video concepts" — two mental models at once.
