// Why this is different

A reference that works offline.

Most HTTP status code references are ad-heavy web pages that require an internet connection. fwip works offline with instant search.

fwip works differently. The reference engine runs entirely in your browser. Your reference is read from your device, processed on your CPU, and the result is saved back to your device. No server is involved. We literally cannot see your file.

No server processing

Everything runs on your device using WebAssembly. Your file never touches a network.

No account required

Drop a file. Get a result. No sign-up, no email, no password.

No subscription

Free in the browser. $99 once for the offline bundle. That's it. Forever.

Works offline

The desktop version works with no internet connection at all.

// Questions

Frequently asked.

What HTTP status codes are included?▾
All standard HTTP status codes from the IANA registry: 1xx Informational, 2xx Success, 3xx Redirection, 4xx Client Error, and 5xx Server Error. Including WebDAV codes and RFC 2324 (418 I'm a Teapot).
Can I search by code number or name?▾
Yes. Type a number like "404" or a name like "not found" and fwip instantly filters all matching status codes.
Does this work offline?▾
Yes. The entire reference is built into the page. No API calls, no server requests. Once loaded, it works without an internet connection.
