Frequently asked questions

Does it support every curl flag?+

It covers the most common flags: -X (method), -H (headers), and -d/--data (body). Highly unusual flags may not be parsed.

Browser dev tools let you copy any network request as a curl command, but most frontend code needs that same request expressed as fetch(). This tool parses the URL, HTTP method, headers, and request body out of a curl command and generates working fetch() JavaScript you can paste straight into your code, saving the tedious manual translation every time you need to reproduce a request from the Network tab.
