Assemble a cURL command visually
cURL is powerful but its flags are easy to misremember, and a complex request is fiddly to type correctly. This builder assembles a cURL command from headers, authentication and a JSON body, giving you a clean command to copy.
Why building beats typing
A cURL command for anything beyond a simple GET accumulates flags for headers, auth, content type and body, and getting the quoting and ordering right by hand is a common source of frustration. Building it from fields, adding each header, setting the auth, providing the JSON body, produces a correct command every time, properly quoted and ready to run or share. It is especially useful for constructing a request to document or to hand to someone else, where a clean, correct command matters.
A correct command, copied
It runs entirely in your browser, so nothing you paste is uploaded and the result is yours to copy straight into a project. Because it works client-side, you can use it on private code and data without anything leaving your machine.

Frequently Asked Questions
What can I add to the command?
Headers, authentication and a JSON body, assembled into a clean, correctly-quoted cURL command ready to copy.
Why build rather than type cURL?
Because complex requests accumulate flags whose quoting and ordering are easy to get wrong by hand. Building from fields produces a correct command every time.
Is it good for sharing requests?
Yes. A clean, correct cURL command is a portable way to document a request or hand it to someone else to run.
Does it handle authentication?
Yes. Authentication can be added, and it is included in the generated command in the correct form.
Is my input uploaded?
No. The builder runs entirely in your browser.
