Hey Product Hunt! 👋
I built ColorContrast because every other contrast checker either required a login, locked features behind a paywall, or only did basic WCAG math. I wanted everything in one place — WCAG 2.x, APCA, URL scanning, color blindness sim, the works — all free, no catch.
A few things we do that most free tools don't:
- APCA perceptual contrast (the WCAG 3.0 algorithm) alongside standard WCAG
- Live URL scanner that audits every visible text element on any page
- 15+ specialized checkers for gradients, buttons, links, headings, icons, forms, and more
- Chrome extension + Figma plugin so you don't have to leave your workflow
Everything runs in your browser —zero servers, zero data collection, zero limits. Open any tool and it just works.
Happy to answer questions and would love feedback on what to build next!
