cURL Command Playground

Interactive learning environment for mastering cURL - test commands, see live results, and understand HTTP interactions with real-time feedback.

No server required • Runs entirely in your browser

cURL Command Builder

Basic GET Request
Most Common

Retrieve data from a URL. This is the simplest cURL command, equivalent to visiting a webpage in your browser.

POST with JSON Data
API Interaction

Send data to a server (commonly used for creating resources in REST APIs).

Custom Headers & Authentication
Secure Requests

Send requests with custom headers, authentication tokens, or API keys.

Pro Tip

Add -i to your cURL commands to include HTTP headers in the response output, or -v for verbose output showing the entire request/response cycle.

Live Response Terminal

Command Output

$ Welcome to cURL Playground!
This is a safe environment to test cURL commands. Click any "Execute" button to see live HTTP responses.
All requests are proxied through a CORS-friendly service to avoid browser security restrictions.
$ Ready to execute your first command...
Status: Ready
Response Time: 0ms
How This Works

This playground uses a CORS proxy to make requests from your browser. Real cURL commands are executed against test APIs. For security reasons, actual authentication tokens are simulated.

Essential cURL Examples

Save Output to File
Download content directly to a file using the -o flag.
curl -o output.html https://example.com
Follow Redirects
Automatically follow HTTP redirects (3xx responses).
curl -L https://bit.ly/shortened-url
Limit Transfer Rate
Throttle download speed (useful for testing).
curl --limit-rate 100K https://example.com/largefile.zip
Ignore SSL Certificate
Useful for testing with self-signed certificates.
curl -k https://self-signed.example.com
Verbose Output
See detailed request/response information.
curl -v https://jsonplaceholder.typicode.com/posts/1

Identify as a specific browser or client.
curl -A "MyCustomClient/1.0" https://httpbin.org/user-agent
