Impeccable
impeccable.style/
Impeccable is a design-checking tool for AI coding agents (Claude Code, Cursor, GitHub Copilot, and others) that runs automated checks against generated interfaces to catch what it calls "AI slop" before it ships. It cites 61 automated checks and shows concrete before/after performance numbers from real fixes, such as page load dropping from 3.4s to 1.1s and JS bundle size from 412 kB to 86 kB. Social proof comes from over 30 embedded tweets with handles and photos rather than conventional testimonial blocks or company logos. The copy is unusually profane and casual for a developer tool's homepage, with lines like "it fucking works beautifully," a deliberate departure from typical dev-tool marketing register.
