IPLogs vs ipdata
ipdata is an IP-intelligence API whose VPN flag and reputation scores start on its paid Business plan. IPLogs is a free, no-signup service that returns a score, a verdict and every matching signal for VPN, proxy and Tor checks. Pick ipdata for timezone, currency, company and carrier data with an SLA; pick IPLogs for free anonymizer detection.
What ipdata is
ipdata is a commercial IP-intelligence API covering geolocation, ASN and company data, mobile carrier, blocklists and anonymity detection for IPv4 and IPv6. Its free tier gives 1,000 city-level lookups a day with no key, then unlimited country and ASN data; the VPN flag and the four 0-100 reputation scores are part of the Business plan and above. Its site describes continuous internet-wide scanning for VPN and proxy servers across 200+ providers, and states 98.4% detection with a 0.2% false-positive rate from its own monthly benchmark.
Pricing, free-tier limits, and feature sets change. Verify current details on ipdata before deciding. This page reflects publicly documented behavior as of 2026-11-02.

When to choose IPLogs
- You want VPN, proxy and Tor detection without a paid plan or an API key.
- You want every matched signal with its weight and last-seen time, not only flags and scores.
- You want the address itself probed for VPN and proxy protocols at lookup time.
- You want a measured false-positive rate, with details published at iplogs.com/accuracy.
When to choose ipdata
- You need timezone, currency, company or mobile-carrier fields in the same response as geolocation.
- You need a contractual uptime SLA, priority or dedicated support, or invoice billing.
- You want 0-100 VPN, proxy, threat and trust scores to feed a threshold-based risk model.
- You need downloadable data on an Enterprise plan or an EU-hosted endpoint.

IPLogs publishes its detection accuracy openly: 0.4% false-positive rate on an ASN-validated corpus. For live, head-to-head API responses across six vendors on controlled test IPs, see the empirical VPN-detection API test.
FAQ
Is IPLogs a free alternative to ipdata for VPN detection?
For VPN, proxy and Tor checks, yes. ipdata's free tier covers geolocation and ASN data, while its VPN flag and reputation scores sit on the Business plan and above. IPLogs returns VPN, proxy, Tor and relay verdicts free with no signup. It does not replace ipdata's timezone, currency, company or carrier data.
Do both publish a false-positive rate?
Yes. IPLogs publishes 0.4% from a labeled ground-truth corpus run against production, with details at iplogs.com/accuracy. ipdata states a 0.2% false-positive rate and 98.4% detection from its own monthly benchmark. The two corpora differ, so the figures are not directly comparable.
What does ipdata offer that IPLogs doesn't?
Timezone, currency, company and mobile-carrier fields, 0-100 reputation scores, commercial blocklists, an uptime SLA on higher plans, priority support, an EU endpoint and data downloads on Enterprise. IPLogs has no paid plans, SLA or downloadable geolocation database.
