Curl Command Generator – Build cURL Commands Online Free
About the Curl Command Generator
The Curl Command Generator builds complete, properly escaped cURL commands from a simple form, so you don’t have to hand-write quoting for headers, JSON bodies, or authentication tokens. Set your URL, HTTP method, headers, and request body, then choose from Basic Auth or Bearer Token authentication and toggle advanced flags like verbose output or SSL skipping.
It’s built for developers testing APIs, writing documentation examples, or debugging requests without opening a full API client. Once you’ve generated your command, the JSON Formatter is handy for validating the request body before you send it, and the JWT Encoder/Decoder is useful if your Bearer Token is a JWT you need to inspect first.
Our team tested this generator across GET, POST, and PATCH requests with special characters in the body, multiple custom headers, and both authentication types to confirm the escaping stays shell-safe every time.
How to Use the Curl Command Generator
- Enter your Request URL and choose an HTTP Method.
- Add any Headers, one per line, in
Header-Name: valueformat. - Paste your request body into Data / Body for POST, PUT, or PATCH requests.
- Select an Auth Type and fill in the username/password or bearer token fields.
- Toggle any Advanced Options, then click Generate cURL and copy or download the command.
Example Usage
Input: URL: https://api.example.com/v1/users, Method: POST, Body: {“name”: “Jane”}, Auth: Bearer Token
Output:
curl -X ‘POST’ \
-H ‘Content-Type: application/json’ \
-H ‘Authorization: Bearer your_api_token_here’ \
–data ‘{“name”: “Jane”}’ \
‘https://api.example.com/v1/users’
The command is broken across multiple lines with backslash continuations for readability, and every value is quoted safely for direct use in a terminal. If your URL contains query parameters that need cleanup first, the URL Encoder/Decoder can help prepare it before you generate the command.
Frequently Asked Questions
Yes, every value including the URL, headers, and body is properly escaped for shell use, so special characters like quotes and spaces won’t break the command.
Basic Auth sends a username and password using curl’s -u flag, while Bearer Token adds an Authorization header with the token, which is the format most modern REST APIs expect.
No, the data/body field is only included in the generated command for POST, PUT, PATCH, and DELETE methods, since GET requests typically don’t carry a body.
It adds the -k flag, which tells curl to skip SSL certificate verification, useful for testing against local or self-signed certificate environments.
Yes, it’s completely free with no signup required.
