WHY IT'S FLAWLESS

Not a screen recorder. A render engine.

Virtual clock

We advance a deterministic clock per frame instead of recording in real time — the render never races your CPU.

Every frame captured

No dropped frames, no tearing. CSS, GSAP, canvas and SVG come out exactly as designed.

One drop, every format

A single HTML file produces 16:9, 9:16 and 1:1 at once — ready for YouTube, TikTok and Reels.
