About Rocket Validator A11y Panel
Rocket Validator A11y Panel opens a side panel beside the page you are on and checks it against 95 rules from AccessLint Core, running against the rendered DOM — after your JavaScript has run, not the source HTML. Every rule links to a Rocket Validator guide explaining how to fix it.
• One scroll, worst first — Critical, Serious, Moderate and Minor, each headed by its count, with filter chips to narrow to one severity at a time.
• It follows you — navigate or switch tabs and the panel re-checks on its own, keeping your filter, your open cards and your place in the list.
• It says when it has fallen behind — infinite scroll or a view swapped in place makes the Re-check button pulse, and leaves the checking to you.
• Four buttons under every failing element — HTML shows the markup the engine saw, Selector copies the CSS selector, Highlight rings the element on the page, and AI Prompt copies the whole issue ready to paste into a chat.
• Every rule explains itself — the engine's own guidance in the panel, and the fuller Rocket Validator guide one click away.
• Light and dark, following your Chrome theme.
Your browsing stays yours. Nothing is collected: no analytics, no telemetry, and no page content ever leaves your browser. The checks run locally and the fonts ship inside the extension rather than being fetched from a font service. The only network requests are the ones you make by clicking a link.
Free companion extension for Rocket Validator, which scans entire websites — thousands of pages in one go, with three engines over every page: AccessLint, Axe and the W3C Validator.
Accessibility checking is bundled from AccessLint Core (MIT), by Cameron Cundiff.
