AnimateIt brings Remotion-style programmatic video to Ruby on Rails — without React or a JavaScript project. Build videos as code: a Ruby class plus a HAML template, using your app's own components, styles, fonts, and real data. Every frame is a real web page, so anything you can render in your app you can put in a video. Preview frame-by-frame in the bundled Studio, then export to MP4/WebM/MOV/GIF with headless Chromium (Playwright) + FFmpeg. Built for indie hackers and Rails developers who want to promote their projects with polished product demos, launch clips, and social ads — without leaving Ruby, hiring an editor, or learning After Effects.
