# HTTP Status Codes

Complete HTTP status code reference. Search by code or name, click to copy. Grouped by category with plain-English descriptions.

## How It Works

1. **Browse or search** — Scroll through all HTTP status codes grouped by category, or type in the search box to filter by code number or name.
2. **Click to copy** — Click any status code to copy it (e.g. '404 Not Found') to your clipboard.
3. **Reference the description** — Each code includes a short description explaining when it's used and what it means.

## FAQ

### What do the color categories mean?

Blue (1xx) = informational, Green (2xx) = success, Amber (3xx) = redirection, Orange (4xx) = client error, Red (5xx) = server error.

### Are all standard codes included?

Yes. Every code from RFC 9110 and common extensions like 418 (I'm a Teapot) and 451 (Unavailable for Legal Reasons) are included.

### What's the difference between 301 and 302?

301 is a permanent redirect — search engines transfer ranking to the new URL. 302 is temporary — the original URL keeps its ranking. Use 301 for URL changes, 302 for temporary maintenance or A/B tests.

### What does 204 No Content mean?

The server processed the request successfully but returns no body. Common for DELETE requests or form submissions where no response data is needed.
