Resources

Tools, checklists, and guidance for web accessibility. Everything here is something I've actually used — this isn't a complete directory, just what has worked for me.

  WAVE (browser extension)

  Fast, free, and easy to read, showing what a page gets right alongside what needs fixing. I like the AIM Score summary, and being able to turn off styles to see a page's raw structure without CSS. It also runs directly in the browser, so it reaches pages behind SSO or on intranets that the public web tool can't. Internal sites deserve the same accessibility standard, even though the public never sees them. Paired with a screen reader and keyboard-only navigation, it gives a solid baseline before further testing.

  Lighthouse

  Built into Chrome DevTools and free, it checks four categories: Accessibility, Performance, Best Practices, and SEO. Performance is a Google ranking factor, through Core Web Vitals, so a bad score has a cost for a public-facing site. Accessibility shapes things that matter too: better semantic structure helps crawling, and a site people can use is one they stay on. Lighthouse admits automated checks only catch a subset of accessibility issues, and recommends including manual testing. web.dev's guide to manual review is worth reading.
