The generated command runs entirely on your own machine when you paste it into a terminal - nothing is sent from this page.

What Is a cURL Generator?

cURL is a widely used command-line tool for making HTTP requests. Its flag syntax (-X, -H, -d, and so on) is powerful but easy to get wrong by hand, especially with quoting. This generator builds a correctly escaped cURL command from a simple form.

Why Use This Tool?

Useful for documentation, support tickets, sharing a reproducible request with a teammate, or quickly testing an endpoint from a terminal without recalling exact cURL flag syntax.

How to Use the cURL Generator

Choose a method and enter the URL.
Add query parameters and headers as needed.
Enter a request body for methods that support one.
Optionally add a basic auth username and password.
Copy the generated command and paste it into your terminal.

Example

Method GET, URL https://api.example.com/status, header Accept: application/json generates:

curl -X GET "https://api.example.com/status" \
  -H "Accept: application/json"

Frequently Asked Questions

Use -X POST (or PUT/PATCH), add -H "Content-Type: application/json" and pass the body with -d '{"key":"value"}'. The generator adds these for you when you enter a JSON body.

cURL's -u user:password option sends an Authorization: Basic header containing the Base64-encoded credentials. Base64 is not encryption, so only use it over HTTPS.

It works as-is in Linux, macOS and Git Bash. In Windows Command Prompt single quotes are not supported, so replace them with double quotes and escape inner double quotes, or use PowerShell's curl.exe.
