A CSS-like language and studio for animating mechanisms

GearScript is a CSS-like language and a free browser studio: list the parts, say how they connect (hinges, gears, belts, pins) and drive one. The studio solves the rest and animates it in 3D. Built for people and AI alike: every error says how to fix it, and agents can check and verify projects through a CLI and MCP server. Export MP4, GIF or an interactive 3D page. No sign-up, nothing to install, open source.

Hi Product Hunt! I built GearScript because animating how machines move (gears, linkages, engines) meant keyframing every part by hand. I wanted to just describe the machine and have the motion worked out.
It’s a CSS-like language designed so AI can write it too: errors say exactly how to fix them, so a model can correct its own code. Write it yourself or with AI, and the browser studio animates it in 3D.
I’d love to hear:
What confused you in your first few minutes?
How did your AI do at writing a mechanism?
What would you use it for?
Free, open source, no sign-up. Thanks for trying it!
