A11y Preflight

Paste any page URL and get a quick accessibility “sanity check” (missing alt, missing labels, heading issues, landmarks, and a few helpful best-practice hints). Includes copy/paste fix ideas.

⚡Heuristic preflight • No DB • 1MB fetch cap • SSRF guarded
What this checks: html[lang] missing/empty title img alt form labels link/button names heading order main landmark skip link focus hint

Limitations: This doesn’t evaluate color contrast, dynamic JS behavior, ARIA correctness, or keyboard traps. It’s meant to catch common “oops” issues fast.
