Rotating Proxy Checker
Rotating proxies hand you a single gateway endpoint that assigns a different exit IP on each connection. This checker connects through the gateway and shows you the exit IP it gave, along with its country, ISP, type, and latency, so you can confirm the rotation is working and see what your requests actually look like from the other side. Run it a few times to watch the exit change.
Live checking is discontinued
ProxyChecker.dev no longer runs proxy checks, the API, MCP tools or paid plans. Nothing on this site tests a proxy anymore. The guides below still explain how proxy testing works and what to look for.

Frequently asked questions
How do I check a rotating proxy?
Paste the gateway endpoint (host:port with your credentials) like any other proxy. Each check connects fresh, so the exit IP you see is the one the gateway assigned for that connection. Run it repeatedly to confirm it rotates.
Why does the same rotating proxy show a different country each time?
That's rotation working. Backconnect gateways pull from a pool of IPs across many locations, so each connection can land in a different country unless you've pinned a region or sticky session in the credentials.
What is a sticky session?
A sticky session keeps the same exit IP for a set window (often 1 to 30 minutes) instead of rotating every request. Providers usually control it with a session ID in the proxy username, which is useful for flows that need the same IP across multiple steps.
Can I confirm my sticky session is actually holding an IP?
Yes. Check the gateway a few times in quick succession with the sticky session credentials. If it's working, the exit IP stays the same until the session window expires.
