React accessibility checker
React encourages composition, but accessibility is still about the rendered DOM: roles, names, focus, and announcements.
Run a free scan
Point the scanner at a deployed preview URL. Static export or SSR pages work best for single-pass scans.
Why combine with dev tooling
eslint-plugin-jsx-a11y catches many patterns in source. Our scan validates what users actually get after bundling, including third-party components.
Client-side routing
Single-page apps change views without full reloads. Test primary routes individually; a one-shot scan may miss issues that appear only after navigation or data load.
Focus management
Dialogs and drawers must move focus and restore it on close. Automated rules flag some problems, but complex widgets need manual keyboard testing.
Design systems
Centralize accessible primitives—buttons, links, inputs—and scan representative pages that exercise them.
