HTTP Status Codes

A compact, color-coded reference of HTTP response status codes from 100 through 511. Each card shows the numeric code, the official reason phrase, and a category label (Informational, Success, Redirection, Client Error, or Server Error). The list is hardcoded inside the component and is searchable by code or phrase.

1. Type into the search box to filter by code number or by reason phrase (case-insensitive). 2. Cards are laid out in a responsive grid; each card's left border color indicates its category. 3. When the filter matches nothing, a no-match message is shown.

1xx Informational is blue, 2xx Success is green, 3xx Redirection is sky-blue, 4xx Client Error is yellow, and 5xx Server Error is red. The dataset includes registered IANA codes plus less common ones such as 103 Early Hints, 226 IM Used, 418 I'm a Teapot, 425 Too Early, and 451 Unavailable For Legal Reasons.
