IPLogs vs vpnapi.io
vpnapi.io and IPLogs both detect VPN, proxy, Tor, and Private Relay IPs. vpnapi.io returns boolean flags with a free 1000-request daily tier that requires an account and API key. IPLogs is free with no signup, adds seven direct VPN-provider APIs and active protocol probing, separates Apple Private Relay and WARP, and returns per-signal provenance with a published false-positive rate.
What vpnapi.io is
vpnapi.io is a focused VPN, proxy, Tor, and Private Relay detection API that also returns city-level geolocation. It offers a free account tier of 1000 requests per day and paid plans for higher volume; an API key is required on every request. It is close to IPLogs in mission and simple to integrate, returning boolean anonymizer flags rather than per-signal provenance.
Pricing, free-tier limits, and feature sets change. Verify current details on vpnapi.io before deciding. This page reflects publicly documented behavior as of 2026-06-02.

FAQ
Is IPLogs a free alternative to vpnapi.io?
Yes. Both have free usage, but vpnapi.io requires a free account and an API key on every request, capped at 1000/day. IPLogs needs no signup or key and adds per-signal provenance, active probing, and a published false-positive rate.
Does IPLogs require an API key like vpnapi.io?
No. IPLogs has no signup or API key. vpnapi.io requires a key parameter on every request, even on the free tier.
Do both detect Apple Private Relay?
Both flag it. IPLogs keeps Apple Private Relay, Cloudflare WARP, and commercial VPNs as distinct signals rather than collapsing them into one VPN flag.
