Free cURL Command Generator Online
Build cURL commands from a form — method, URL, headers, auth, and body — then copy the ready-to-run command.
How it works
Enter the URL
Type the API endpoint or URL you want to make a request to.
Set method and headers
Choose GET, POST, PUT, PATCH, or DELETE. Add custom headers and auth.
Add a request body
For POST/PUT/PATCH, enter JSON or form body data.
Copy the cURL command
The generated command updates live — copy and paste into your terminal.
Common use cases

Build cURL commands to test REST API endpoints without needing Postman or Insomnia installed.
Documentation examples
Generate cURL examples for API documentation that developers can copy-paste directly.
Debugging requests

Frequently asked questions
What authentication methods are supported?
Bearer token (Authorization: Bearer ...), Basic auth (username:password encoded), and custom headers for API key auth.
Are my credentials sent anywhere?
No — the command is generated entirely in your browser. Your auth tokens and passwords never leave your tab.
Does this actually execute the request?
No — this is a command generator only. Copy the command and run it in your terminal. For in-browser testing use the API Tester tool.
Can I generate curl for multipart form data?
Select "Form data" body type to generate -F flags for multipart/form-data requests.
