Free proxy tools
Quick tools to verify your connection and your proxies, free to use.
These tools are free and need no account. Most of them run their checks from our server; the WebRTC leak test runs in your own browser. Use them to test a proxy before you buy more, to see what websites learn about your connection, or to find out why a setup stopped working.
A typical check: confirm the proxy answers with the proxy checker or the speed test, look up the exit IP to see its country, ASN and whether it is detected as a datacenter IP, then run the WebRTC leak test in the browser profile you will actually use, so your real IP does not show up next to the proxy IP.
Results reflect the moment of the test and our server's network, so repeat a slow or failed check before drawing conclusions.
