proxycheck.io alternative — proxy detection is one signal, cross-check it

proxycheck.io is a service specialized in proxy/VPN detection: it judges whether an IP is a proxy/VPN and adds a risk score. It's API-first, with a limited daily free tier (API key required) and paid beyond. IPOK uses proxycheck as one of its aggregated sources.

Proxy detection is one signal in IPOK's score, not the whole picture. A non-proxy address may still carry hosting, abuse, or non-native evidence; that does not mean ChatGPT, streaming, or another platform will reach the same conclusion.

IPOK (ipok.io) is free and no-key, showing proxy-style detection beside the other sources actually returned for the lookup. Tor, authoritative blocklists, and confirmed proxies use direct-evidence floors; hosting is contextual with a floor of 35. Native status and a /24 profile add context without claiming every wired source returned.

FAQ

Is proxycheck.io free?

proxycheck.io offers a limited daily free quota (API key required), paid beyond, and is mainly an API for developers to integrate. For an instant web check with no key, use IPOK.

Is proxy detection alone enough to judge whether an IP is clean?

No. Proxy detection is one signal. IPOK shows it beside whichever other sources actually returned from up to 8 wired signals, then adds nativeness and /24 context; dormant or failed sources are excluded.

Is there a no-API-key proxycheck alternative?

Yes. IPOK (ipok.io) lets you enter an IP on the page with no signup and no key, aggregating up to 8 sources (including proxycheck-style detection) plus native/datacenter and /24 profiling.

Does IPOK use proxycheck too?

Yes. proxycheck is one of up to 8 wired sources. Dormant or failed sources are excluded, so you see its verdict beside whichever other sources actually returned for that lookup.
