HTTP Status Code Reference
A searchable, filterable reference for every HTTP status code — with plain-English explanations and real-world usage notes.
Every developer has stared at a 422 wondering if it’s their fault or the server’s. The HTTP Status Code Reference is a searchable, filterable cheat sheet that covers the complete set of standard codes — with plain-English explanations that cut through the RFC jargon.
Key Features
- Instant Search: Filter by code number, name, or keyword as you type.
- Category Tabs: Jump directly to
1xx,2xx,3xx,4xx, or5xxgroups. - Plain-English Notes: Each card explains when you’d encounter the code in the real world, not just what the spec says.
- Copy-Friendly: Click any code to copy it to your clipboard instantly.
[!TIP] Type a keyword like “cache”, “auth”, or “redirect” in the search bar to find codes by concept rather than by number.
