What is My IP Address & WebRTC Leak Checker
Verify your active public IP, geographic location, ISP network, and test for WebRTC address leaks to ensure your cloud browser instance or MCP agent is completely anonymous.

đĄī¸ WebRTC Leak Detection
WebRTC can bypass proxy layers and cloud browser bindings by querying local network interfaces via STUN protocols, exposing host IP addresses to anti-bot firewalls.
Need Completely Anonymous Cloud Browsers with Zero IP Leaks?
Use 2Captcha Cloud Browser (#1 Editor's Pick). Run authentic Google Chromium instances in GPU-accelerated sandboxes with integrated residential proxy routing, automated WebRTC masking, and built-in CAPTCHA solving starting at $0.05/hour.
How Cloud Browsers & MCP Agents Prevent IP Leaks
When executing automated web workflows, target security systems (Cloudflare, DataDome, Akamai) cross-reference multiple IP signals: HTTP request origin headers, TCP socket handshakes, and STUN candidate addresses emitted by browser WebRTC APIs.
Why WebRTC Leaks Defeat Standard Proxies
Even when standard headless Chromium routes HTTP requests through an upstream proxy, default WebRTC implementations query local network interfaces directly. If STUN queries bypass the proxy tunnel, your real IP is exposed in JavaScript readbacks, resulting in instant bot flags.
Verifying Cloud Browser Stealth
Navigate to this page using your Playwright or Puppeteer script via your remote WebSocket endpoint (`browserWSEndpoint`). If properly configured, the IP address displayed above will match the cloud provider's proxy exit IP, and the WebRTC candidate check will report zero local host leaks.
