7 instant, no-signup tools to inspect your connection -- check your IP, run the proxy tester to check any proxy's connectivity, speed, and anonymity, catch DNS and WebRTC leaks, and view your HTTP headers and user-agent string. All run in your browser.
View the HTTP request headers your browser sends to websites, including User-Agent, Accept, and proxy-revealing headers.

The Proxy Tester below is your proxy checker for one endpoint at a time -- paste a proxy and see its connectivity, speed, exit IP, and anonymity level in seconds. To check a full list, run each proxy through it, or call the same check from your own script with the API.
A leak happens when your DNS queries or WebRTC connections bypass your proxy and reveal your real IP or location. Testing confirms your setup is actually private -- a common failure that undermines otherwise-correct proxy configuration.
A browser fingerprint is the combination of signals -- user-agent, screen, fonts, canvas, TLS handshake -- that sites use to identify you even without cookies. The User Agent Parser and HTTP Header Viewer below show two of the biggest signals that make up your fingerprint.
Yes. Most tools have an API equivalent documented in the API reference, so you can automate IP checks, geolocation lookups, and proxy testing inside your own pipelines.
These tools show what one connection looks like. Spin up a KnoxProxy endpoint to run the same checks across thousands of clean IPs.
