FFraud
The free, open IPQualityScore alternative.
IPQualityScore (IPQS) is a fraud-prevention API known for proxy/VPN detection and a fraud score. FFraud gives you the same signals, plus a fraud score, abuse history, open ports and WHOIS, free for everyone, with no usage caps, and published as MIT open data.
FFraud vs IPQualityScore.
| Feature | FFraud | IPQualityScore |
|---|---|---|
| Price | Free, forever | Paid, per lookup |
| Fraud score | Yes (0-100) | Yes |
| Proxy / VPN / Tor | Yes | Yes |
| Threat categories + tags | Yes | Limited |
| Open ports + CVEs, WHOIS | Yes | No |
| Open data (MIT) | Yes | No |
| Drop-in migration | One URL | n/a |
Usage-based paid plans, priced per lookup volume.
Change one URL. Keep your code.
FFraud mirrors the IPQS proxy-detection fields your integration already parses (fraud_score, proxy, vpn, tor, recent_abuse, connection_type), so you can switch by changing one URL and stop paying per lookup.
