A proxycheck.io alternative for VPN and proxy detection

proxycheck.io answers whether an address is a proxy or a VPN, who operates it, and when it was seen. VPNDetection gives each kind of proxy its own flag, counts the days in 90 it turned up and how many providers resell it, and names the hosting company. Paid plans start at $19 a month for 250,000 lookups.

We found none of these figures on proxycheck.io's site on 2026-11-13. Ours are counted from 2026-11-13's build of the data every lookup answers from. No independent list of every VPN address exists to test the APIs against, so each count is the company's own.

Where proxycheck.io does more

proxycheck.io is cheaper at small volumes: $4.99 a month buys 10,000 queries a day. It also scores risk, keeps the attacks it saw from an address, and checks disposable email.

Ours flags each kind of proxy on its own, residential, mobile, datacenter and public, with how many of the last 90 days it turned up and how many providers resell it, where proxycheck.io drops a residential proxy 48 hours after it was last seen unless asked for more days. Ours also names the hosting company, and answers the VPN, Tor and relay flags with no key at all.
