Where can you use Reddit?
Almost everywhere, except: China.
Your browser checks Reddit over the route you normally use for it, and the other services too.
Almost everywhere, except: China.
Reddit doesn't let other sites read any of its answers, and doesn't redirect by region. So the page can only check that it opens over your route, and compares the country other services place you in with Reddit's list. The result is marked "Guess".
Each service locates IPs with its own database, and they don't always agree: the same proxy can be in Japan for one and Hong Kong for another. Some services also turn away datacenter IPs and known VPNs. The country shown is the one Reddit itself sees.
Proxy apps (Clash, Surge, Shadowrocket and the like) send different sites over different routes. A script on a server only tests that server's IP. This page visits each service from your browser, over the route you normally use for it.
How reliable a result is, most reliable first. Official API: the service's own region API says whether it works. Its location: the service's servers say which country they place you in, checked against the countries it publishes. Redirect test: whether the service sent you to its "not available" page. Guess: the service lets nothing be read; the page only knows it opens, and takes the country other services place you in.
Your proxy rules may send them through different servers, or the services use different IP databases. When that happens, the page lists which services see which country.
AI services compare your browser's time zone with your IP's country. A time zone in China with an IP in the US looks like a proxy and can trigger stricter checks.
No. Your browser visits each service directly; this site only serves the page and never sees your results. Use Hide IPs before a screenshot.
