An IPQualityScore alternative for VPN and proxy detection
IPQualityScore scores how risky an address looks. VPNDetection tells you what it is: the VPN service by name, the proxy pool it sits in, the company that hosts it, and when we last saw it there. Paid plans start at $19 a month for 250,000 lookups.
50,000 free lookups a month. No card needed.
Side by side
What each API answers for one address, from each company's own documentation.
| Question | VPNDetection | IPQualityScore |
|---|---|---|
| Which VPN | Named on every paid plan, as vpn.provider: a stable ID a rule can key on. | No field is documented to name the service. vpn and active_vpn say yes or no. |
| How sure, and how recent | confidence (high, medium or low) and last_seen on every match. | A fraud_score: 75 and up is suspicious, 90 and up high risk. |
| Residential proxies | is_resproxy, with first and last seen, hits, days seen and how many providers resell the address. | Inside proxy, which also covers VPN and Tor. connection_type can read Residential. |
| Datacenter, mobile and public proxies | is_dcproxy, is_mobproxy and is_pubproxy, each a flag of its own. | One proxy flag for every kind. |
| Tor | is_tor, from the public Tor set, rebuilt daily. | tor, and active_tor for exits active now. |
| Hosting | is_hosting, with the hosting company named. | connection_type reads Data Center. |
| Free to start | 50,000 lookups a month, no card. A free key answers the VPN flag, Tor, relays, location and network. | 1,000 free lookups, as its plans page offers them. |
Where IPQualityScore does more
IPQualityScore sells a fraud suite. Its score weighs the address with the browser's user agent and language, it reports abuse its own network saw recently, and it also validates email addresses and phone numbers, fingerprints devices and scans URLs.
We do none of that. We answer one question about an address, what it is, with the evidence behind the answer, and leave the decision to your rules. If you want one vendor for every fraud signal, IPQualityScore is built for that.
