HTTP Tools — cURL, Messages, URLs, HAR, Cookies
Paste-local cURL, HTTP messages, URLs, HAR files, and Cookie / Set-Cookie headers — format and inspect in your browser. Convert a request to fetch, HTTP/1.1, or .http on the formatter. Inspect a HAR. Parse Set-Cookie. FastMinify never sends the request and has no runner. Working on an OpenAPI or JSON Schema spec? Open the API & schema tools hub.
- Turn a Chrome Copy as cURL one-liner into readable multi-line cURL, fetch, or Python requests.
- Inspect a raw HTTP/1.1 request or response, including duplicate headers and JSON bodies.
- Decompose a URL, edit the query table, and copy a rebuilt URL — password masked by default.
URL Parser
Decompose a URL into protocol, host, path, query table, and hash — edit query rows, rebuild, password masked.
cURL Formatter
Format Chrome Copy as cURL into multi-line, one-line, JavaScript fetch, or Python requests — sanitize Cookie and Authorization before you share.
HTTP Message Parser
Parse a raw HTTP/1.1 request, response, or header block — start-line, duplicate headers, JSON pretty-print. HTTP header parser, in the browser.
Cookie / Set-Cookie Parser
Paste Cookie or Set-Cookie, edit RFC 6265 attributes, see SameSite and prefix flags, and copy a rebuilt header — never written to the cookie store.
HAR Inspector
Drop a HAR, filter the call list, extract cURL or HTTP/1.1, and download a sanitized file — never uploaded, never replayed.
