MaxMind alternative โ for a human check, no .mmdb download or minFraud API
MaxMind is a long-established IP data vendor: GeoIP2 provides a geolocation database (download the .mmdb or call the API), and minFraud provides fraud scoring. It targets developers โ you embed the database in your program or pay per call, with accuracy and volume on paid tiers.
For a team judging traffic in bulk, programmatically, in a product, that's the right shape. But if you just want to manually check whether one IP is clean or a datacenter/proxy, downloading a database or wiring up the minFraud API is over-engineering.
IPOK (ipok.io) is the no-signup, free alternative for "check one IP by hand": enter an IP on the page and get results, aggregating 8 risk sources (geo / ASN baseline plus proxy / abuse / fraud verdicts) into an explainable conclusion, with native/datacenter and /24 neighbor profiling. No database download, no API key.
