cURL Builder

Build a complete cURL command locally with methods, parameters, headers, request bodies, and authentication.

This generator assembles a command without sending a request. The URL must be absolute and use HTTP or HTTPS. Enter query parameters as key=value lines; they are appended to the existing query with appropriate encoding. Repeated keys remain separate parameters. Headers use Name: value. For names that match without case sensitivity, the last value replaces the previous one.

Commands use POSIX shell quoting, including apostrophe escaping. They suit shells such as sh or bash rather than automatically working in PowerShell or cmd. HEAD produces --head. A JSON body is checked for syntax and receives Content-Type: application/json unless you supplied that header already. Text uses --data-raw, while form mode adds --data-urlencode for each line. It does not build multipart file uploads.

Redirect, compression and TLS verification options are written into the command. --compressed requests a compressed response and lets cURL decode it; it does not compress your outgoing body. --insecure disables certificate verification and can hide a real problem. Bearer tokens or usernames and passwords appear in plain text in the generated command. Copying or running it in a terminal can expose them through history or logs.
