HTTP Status Code Reference is a free online api tool that searchable reference of all http status codes with descriptions and use cases. It works entirely in your browser — no downloads, no installations, and no server uploads required. backend developers, QA engineers, integration specialists use HTTP Status Code Reference when they need a fast, privacy-respecting way to process api data without installing additional software. It supports capabilities such as complete reference, search & filter, code examples. Additional features include quick copy. Common use cases include quickly look up status codes while debugging api responses, learn proper status code usage when designing restful apis, reference rfc documentation for custom api error responses. All processing happens locally using modern browser APIs, which means your data never leaves your device. This makes HTTP Status Code Reference ideal for working with sensitive data, proprietary code, or any situation where privacy matters.

All operations run entirely in your browser using built-in API APIs. No server uploads, no data storage, and no third-party requests.
HTTP Status Code Reference is ideal when you need to quickly look up status codes while debugging api responses without installing software or uploading data to a server. Since everything runs in your browser, there is no setup time and no risk of your data being stored on external servers. For for collaborative API development and testing, consider using Postman. For for lightweight REST and GraphQL debugging, Insomnia may be a better fit. HTTP Status Code Reference fills the gap between heavyweight desktop tools and insecure online services that require uploading your data.
No. HTTP Status Code Reference processes everything entirely in your browser using JavaScript. Nothing you type, paste, or upload is ever transmitted to any server. Your data never leaves your device.
401 Unauthorized means the client must authenticate. 403 Forbidden means the server understood the request but refuses to authorize it, even with authentication.
502 Bad Gateway means the server, acting as a gateway or proxy, received an invalid response from an upstream server it accessed to fulfill the request.
All HTTP status codes from 1xx to 5xx with RFC references.
Filter by category (success, redirect, client error, server error).
Example responses and common scenarios for each status code.

HTTP Status Code Reference is useful in a variety of scenarios across different workflows:
Quickly look up status codes while debugging API responses
Learn proper status code usage when designing RESTful APIs
Reference RFC documentation for custom API error responses
Return 201 Created (not 200 OK) when a POST request successfully creates a new resource, and include the resource URL in the Location header.
Return 409 Conflict when a request conflicts with the current state of the resource, such as duplicate entries or version conflicts.
