IPLogs vs Scamalytics
Scamalytics scores how risky an IP is for fraud, using a proprietary 0-100 score built from fraud reports across surrounding networks; its API has a free tier of 5,000 monthly credits. IPLogs is free with no signup and detects VPN, proxy and Tor addresses, listing every signal. Pick Scamalytics for fraud scoring and on-premises data; IPLogs for anonymizer detection.
What Scamalytics is
Scamalytics is a fraud-intelligence company whose IP Fraud Risk product returns a proprietary 0-100 score with a low-to-very-high risk level, plus proxy, VPN, Tor and datacenter detection, an ISP-level risk score and geolocation. The score is built from fraud feedback reported by a network of operators and applied across the same subnet, ASN and hosting block. The API has a free tier of 5,000 credits a month shared with a no-code bulk CSV tool; premium add-ons (proxy, geolocation, ISP and organization, residential-proxy data) and an on-premises MMDB at a flat fee are available.
Pricing, free-tier limits, and feature sets change. Verify current details on Scamalytics before deciding. This page reflects publicly documented behavior as of 2026-11-02.

When to choose IPLogs
- You want to know whether an address is a VPN, proxy, Tor exit or relay, not how likely it is to be linked to fraud.
- You want every matched signal listed with its weight.
- You want no account, key or credit allowance.
- You want the address probed for VPN and proxy protocols, and a published false-positive rate.
When to choose Scamalytics
- You want a fraud-outcome score for risk teams in banking, payments, classifieds or dating, informed by reported fraud.
- You need lookups to stay in-house: the MMDB runs on your infrastructure and sends no data to Scamalytics.
- You need residential-proxy provider data, premium geolocation or ISP and organization add-ons.
- You want to enrich large IP lists without writing code, using the bulk CSV tool.

FAQ
Is Scamalytics a VPN detector?
It includes proxy, VPN and Tor detection, but its core product is a proprietary fraud-risk score. Its site says the score is built from fraud feedback from operators and applied to nearby addresses in the same subnet, ASN and hosting block, so the score reflects fraud risk while proxy status is returned as separate data. IPLogs answers the anonymizer question directly: is_vpn, is_proxy, is_tor and is_relay with every signal listed.
Is IPLogs a free alternative to Scamalytics?
For VPN, proxy and Tor detection, yes: no signup and 1,000 full lookups a day. Scamalytics also has a free tier of 5,000 credits a month with an account. IPLogs does not produce a fraud-outcome score, an ISP-level risk score or an on-premises database, which Scamalytics does.
What does Scamalytics offer that IPLogs doesn't?
A fraud-feedback risk score with an ISP-level risk score, paid residential-proxy data, a no-code CSV upload tool for large lists, and an on-premises MMDB with unlimited lookups at a flat fee. IPLogs has no paid plans, SLA or downloadable geolocation database.
