Contrast (usecontrast.com) is a free, open-source WCAG color contrast checker, available as both a Figma plugin and a native macOS app.
Being available natively in Figma, not merely as a separate web tool, means contrast ratios show up right where colors are being picked, so accessibility gets checked during design instead of as a later audit step.
Figma users who want contrast checking built directly into their design tool rather than switching to a browser tab to verify each color pair.
The macOS app is open source and hosted on GitHub, useful if the team wants to confirm exactly how contrast ratios are calculated rather than trusting a black-box tool.
A macOS app for quick access to WCAG color contrast ratios.
