Hyperframes
Free alternative to: Remotion
License: Apache-2.0
Free terms: Fully free Apache-2.0 with no per-render fees or commercial-use thresholds; runs locally via npx with Node.js, no HeyGen API key needed.
What it does
HeyGen's open-source HTML-to-video renderer built for AI agents — write plain HTML/CSS/GSAP, render deterministic MP4s via headless Chrome + FFmpeg.
Heads-up: Official repo README (heygen-com/hyperframes): 'Open source: Apache 2.0 license, with no per-render fees or commercial-use thresholds.' Remotion itself is only source-available with paid company licenses — Hyperframes is the OSI-clean alternative.
