Does this actually run the curl command?

No. The command is only parsed and explained — nothing is sent over the network. It's safe to paste a command with real credentials in it; the parsing happens entirely in your browser and the text never leaves the page.

Which curl flags does it cover?

Around 70 of the flags people actually run into day to day — method, headers, data/JSON/form bodies, auth, cookies, redirects, TLS options, timeouts, retries, and more. Anything not in that list is shown as an unrecognized flag with a pointer to `curl --help all` or `man curl`.

Does it handle multi-line commands with backslash continuations?

Yes. Commands copied from browser dev tools or Postman's "Copy as cURL" — including ones that wrap across multiple lines with a trailing backslash — parse the same as a single-line command.

Is my curl command uploaded anywhere?

No. Parsing happens with plain JavaScript in your browser tab. There's no server call, no analytics payload of the command text, and nothing is stored.
