HTTP Status Codes Reference is a free online tool that provides a comprehensive, searchable list of all HTTP status codes. HTTP status codes are three-digit numbers returned by web servers to indicate the result of a client's request. They are grouped into five categories: 1xx (Informational), 2xx (Success), 3xx (Redirection), 4xx (Client Error), and 5xx (Server Error). This tool lets you search by code number or name, filter by category, and click on any code to see its detailed description. It is an essential reference for web developers, system administrators, and anyone working with web APIs.
