Framecast

Claude and the web make it surprisingly easy to build beautiful HTML and CSS animations, but getting them out as clean video has always been a struggle. Screen recording drops frames, bands your gradients, and slaps a watermark on the result.

Framecast loads your animation in a real browser engine and advances a deterministic virtual clock one frame at a time, capturing each frame at full quality before stitching everything into an MP4. The output looks exactly like it did in the browser: true frame-perfect motion, no watermark, and resolution up to 4K.

A single HTML file is all you need to export 16:9, 9:16, and 1:1, so one animation covers every social format. Framecast works with CSS, GSAP, canvas, and SVG. Pricing is $2.99 per video, with no subscription required.
