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.

Could you build this?
Partial The studio UI and CSS-like language are vibe-codeable, but a real mechanism solver for linkages, gears, and belts with 3D animation and useful error messages needs kinematics and constraint-solving expertise.
What it would actually take: Architecture would be a parser for the declarative language, a constraint or kinematic solver (for example, a Newton-Raphson or sparse solver over joint constraints), and a Three.js viewer for animation. The hard part is robust solving across degenerate and over-constrained configurations, which requires mechanical engineering and numerical methods knowledge. Good error diagnostics also require a well-designed constraint model.
