Visual accessibility evaluation that shows problems in place on the page.
WAVE, from WebAIM, overlays icons directly on the rendered page to show errors, alerts, ARIA usage, contrast issues and structural elements, which makes it unusually good at teaching people what an accessibility problem actually looks like. It is free as a browser extension and online tool, with a paid API for bulk scanning.
