  • Category guess for uncommon codes
  • Client-side

Why it Matters

Debugging APIs means translating 422 vs 409 vs 503 under pressure. A searchable status table beats scrolling MDN mid-incident.

★★★★★

Look up any HTTP status from 100–599. Curated entries cover the codes you hit daily; others still get a class guess.

Frequently Asked Questions

Is every IANA code listed?
Common ones are curated. Unknown codes still show a class guess (4xx/5xx).
Is 418 here?
Not in the curated list — lookup still classifies it as 4xx.
Offline?
Yes — data is bundled in the page.
