SpotCheck is a collection of free to use bookmarklets that test for common accessibility issues directly in the browser. Each one maps to its related WCAG 2.2 success criteria.
- No installation. Each tool is self-contained. All you need to do is drag the bookmarklet link to your bookmarks bar and it's ready to use on any site.
- Nothing leaves your browser. Every check runs entirely client-side against the current page's DOM.
- Click again to clear. Running a bookmarklet a second time on the same page removes its outlines and summary panel. Or, you can click the close button in the popup to clear the results. But sit tight, I have something else coming to improve this UX pattern :)
- WCAG 2.2 mapped. Every tool's page lists the specific success criteria related to its bookmarklet, with a link to the W3C Understanding document
- These tools are a starting point, not a full audit. Bookmarklets are great for quick spot-checks that catch common issues, but they don't replace a full manual and assistive tech review.
- Known issues. I know that the gold color used for the "flagged" status is problematic for some with weak color vision. I'm still working on a color option for it.
- Shout out to Jamie Klenetsky Fay for her love of bookmarklets that got me hooked.
- Big up to Donnie D'Amato for being my second set of eyes on this thing.
