GridProof

MCP server that audits rendered UIs for spacing and grid violations so coding agents can fix them in-loop.

Desktopfreeglobal

GridProof is an open-source MCP server and CLI that renders a running frontend with Playwright, measures every element's computed geometry, and reports spacing and grid violations with fix hints, so AI coding agents can audit and correct their own UI output. It targets Tailwind projects and falls back to accessibility-only checks elsewhere.
