Why these tools exist
We don't operate proxy servers — we explain them. What we can offer is the diagnostic half: the checks that tell you what your connection currently looks like to a website, so you can work out why something is or isn't letting you in.
Every tool here runs entirely in your browser. There is no server-side code on this site, no account, and nothing is stored. Where a tool needs data we can't calculate locally — IP geolocation, for instance — your browser asks a third-party service directly, and we say so on the page.
More coming
We're adding tools as we find the gaps our guides can't close on their own. If there's a check you keep wishing existed, tell us — that's how this list grows.
Start with the guides instead
If you're still working out which tool you need rather than testing one you already have, the written guides are the better starting point: choosing a South Korea proxy server, every way to get a Korean IP address, or proxy vs VPN.
