IPinfo competitors and alternatives

The alternatives, briefly

Kaidn compared with IPinfo

Accurate IP context: geolocation, ASN, carrier and company data, with privacy and VPN detection on higher tiers.

IPinfo is a data company, and a careful one. If your problem is that you need to know an address is on a particular carrier in a particular city belonging to a particular organisation, they are excellent and this page is not an argument against them.

It exists because "IP intelligence" gets used to mean two unrelated things, and buying the wrong one wastes a quarter.

Description is not decision#

Their output is descriptive: this address is in Lagos, on this ASN, operated by this company, and on the right plan, using a VPN.

Ours is a judgement about a person: allow, review or block, with the checks that fired and their weights. IP context feeds into that, and so does whether the email domain was registered last week, whether the phone is a VoIP line already seen elsewhere, and whether this device signed up four times today.

Neither is better. But if you buy description and needed judgement, you will build the judgement yourself, and that build is longer than it looks. It is not the API call. It is the weighting, the thresholds, the review queue, and the six months of tuning that follow.

ASN, and the thing we do differently#

We both surface ASN. We use it differently, and it is worth being precise since it is the closest our products come to overlapping.

Theirs is authoritative registry data: which autonomous system an address belongs to and who operates it. That is a fact, and facts are what a data company should sell.

Ours is reputational and first-party: how traffic from that ASN has actually behaved across the operators we score. That is not a fact about the network, it is an observation about our own traffic, and it is only possible because we sit on decisions rather than lookups. It is also worth exactly nothing without their kind of data underneath it.

The honest overlap#

Their privacy detection on higher tiers does overlap with part of what we do, and if that is all you need from a risk perspective, one vendor is simpler than two.

The overlap ends at the address. Nothing in an IP feed will tell you that these eleven accounts withdraw to the same destination, because that information does not exist in an IP address and never will.

Description and judgement, in one screen#

The difference is not rhetorical. It is what the response leaves you holding.

{
  "ip": "3.5.140.1",
  "city": "Seoul",
  "country": "KR",
  "org": "AS16509 Amazon.com, Inc.",
  "privacy": { "vpn": false, "proxy": false, "hosting": true }
}

Every field is true and none of them is a decision. hosting: true is bad news on a consumer signup form and completely normal for an API client, and nothing in the payload knows which one you are.

{
  "verdict": "block",
  "score": 95,
  "reasons": ["datacenter_ip", "device_reuse", "disposable_email"],
  "checks": [
    { "check": "ipRisk", "weight": 45, "reason": "datacenter_ip", "evidence": { "asn": "amazon" } },
    { "check": "deviceReuse", "weight": 15, "reason": "device_reuse", "evidence": { "accountCount": 3 } },
    { "check": "emailRisk", "weight": 35, "reason": "disposable_email", "evidence": { "is_disposable": true } }
  ]
}

The address contributed 45 of the 95. The other 50 came from information no IP feed holds.

If you want the geography without the verdict#

Kaidn will not replace a geolocation database and does not try to. But if all you want is the address on its own, there is a lookup that does not spend a scored event:

curl -s -X POST https://api.kaidn.io/v1/check/ip \
  -H "x-api-key: $KAIDN_API_KEY" \
  -H "content-type: application/json" \
  -d '{"ip":"3.5.140.1"}'

Treat that as a convenience, not as a reason to drop a data vendor. For registry-grade accuracy on what an address is, buy it from a company whose whole business is being right about that.

Where we would send you elsewhere#

If you need geolocation as a self-hosted database rather than an API, MaxMind has been doing that longest. If you only care about proxy-or-not and want to spend as little as possible, proxycheck.io is a few euros a month. And if you are at low volume and want the same shape as IPinfo more cheaply, price ipdata before committing.
