Online curl Tool Guide
Run curl commands from your browser to check your public IP, inspect response headers, and test endpoints without installing curl locally.
An online curl tool runs curl-style requests from a browser sandbox, so you can inspect a response without installing curl or opening a terminal. This is useful on locked-down machines, mobile devices, or when you just want to share a reproducible request.
Check your public IP
The most common use is confirming which IP address the internet sees for you:
curl -s https://rookvpn.com/check/api/ip/address
Run the same request in the browser with RookCurl. It executes the request in a sandbox and shows the response body, headers, and timing side by side.
Inspect headers and timing
Beyond the body, an online curl tool surfaces the response status, headers, and how long the request took. That makes it easy to confirm caching behavior, redirects, and content types without memorizing curl flags like -I or -w.
Verify a VPN from the browser
When you cannot open a terminal, an online curl tool is a quick way to confirm a VPN is routing your traffic. Compare the reported IP with and without the VPN connected. For a complete check that also covers WebRTC, DNS, and IPv6, use the VPN leak test suite and follow the VPN leak testing guide.
curl vs wget vs PowerShell
Different environments ship different tools. The Check Public IP via curl guide covers the equivalent commands for curl, wget, and PowerShell’s Invoke-RestMethod so you can run the same check anywhere.
