Why we built these color contrast and accessibility tools
Accessibility shouldn't be an afterthought you bolt on before launch. But most teams treat it that way because the tooling makes it hard to check as you go. We kept context-switching between axe DevTools, random color contrast checkers, and WCAG spec documents, so we started building the tools we actually wanted in our workflow.
The color contrast checker lets you test any two Tailwind CSS colors against WCAG 2.1 ratios instantly. The website accessibility checker audits any URL across 8 categories. The WCAG and ADA compliance checker gives you a per-criterion pass/fail report. And the color palette generator creates full Tailwind palettes where every shade passes WCAG AA contrast.
Every tool here runs entirely in your browser. Nothing is sent to a server, there's no sign-up, and there are no ads. Check contrast ratios, audit ADA compliance, generate accessible palettes, and get back to shipping. If you have a tool idea that would save you time, let us know.
