httpcodes.fyi is an HTTP status code quick-reference site for developers. The crawled content shows that it lists status codes by category, including 5XX Server Error, 2XX Success, and 3XX Redirection. It includes common codes such as 500, 502, 503, and 504, as well as Cloudflare platform-related error codes like 520, 521, 522, 523, 524, 525, 526, 527, and 530. The page also displays “Edit on GitHub,” suggesting that the content may allow community edits via GitHub.
Functionally, it is more of a lightweight cheat sheet than a full documentation library. Its main value is helping developers quickly identify what category a given HTTP status code belongs to, especially when troubleshooting Cloudflare 5XX errors encountered with CDNs, reverse proxies, or origin server issues. The site states that it is built with Hugo, Tailwind, and Netlify, but the crawled text does not show any API, SDK, search, filtering, code examples, or framework integrations.
The crawled content does not mention any paid plans, subscriptions, or enterprise editions, so it can only be assessed as a free resource available as a public webpage. The page provides a GitHub edit link, but it does not clearly state the source code license, content license, or full open-source status, so it should not be directly assumed to be an open-source project. Self-hosting options are also not mentioned.
Its strengths are a narrow focus, high information density, and virtually no learning curve. It is convenient for developers, testers, and operations teams who need to quickly confirm the category of a status code. The drawbacks are also clear: the currently crawled content appears incomplete, with common status codes such as 200, 202, 302, 400, 401, and 404 not shown. Each status code also lacks explanations, typical causes, troubleshooting steps, protocol references, and example responses, so the documentation depth is limited.
It is suitable for web developers, backend engineers, SREs, testers, and HTTP beginners who need a quick lookup table. It is not ideal for teams that rely on systematic troubleshooting manuals or automated integrations. The crawled text does not provide enough information to determine accessibility from China. Since Netlify-hosted sites can vary in domestic access performance depending on network conditions, this can only be marked as unknown. Alternatives include the MDN HTTP status code documentation, httpstatuses.com, the HTTP RFC documents, and Cloudflare’s official support documentation.
