IPinfo competitors and alternatives
Choose IPinfo instead when
- checkYou want to know what an address is, not whether to trust it. Location, network and company data are their specialism and the quality shows.
- checkYou are enriching analytics, routing, localisation or compliance rather than blocking anybody.
- checkYou want bulk data or downloadable databases rather than an API call per decision.
- checkThe accuracy of the underlying IP data matters more to you than any opinion layered on top of it.
The alternatives, briefly
Kaidn
this is usScores a user event rather than describing an address. IP context, including network reputation built from our own traffic, is one weighted input beside email identity, phone, device and repetition.
MaxMind
site ↗The long-standing incumbent for IP geolocation, with GeoIP databases plus a separate fraud product. Self-hosted database options if you cannot make an API call per request.
proxycheck.io
site ↗Narrower and much cheaper: proxy, VPN and data centre classification without the location depth. The right tool if the only question is whether an address is hiding something.
IPQualityScore
site ↗IP data with a fraud score attached, plus email and phone lookups. More opinionated than IPinfo, less complete on pure geolocation.
ipapi / ipdata
site ↗Similar shape to IPinfo at smaller scale, often cheaper at low volume. Worth pricing if your usage is modest and location is all you need.
Kaidn compared with IPinfo
Accurate IP context: location, network, carrier and company data, with privacy and VPN detection on the higher tiers.
| Kaidn | IPinfo | |
|---|---|---|
| What it returns | allow, review or block for a user event, with reasons. | Facts about an IP address. |
| Question it answers | Should this person go through? | Where is this address, and who runs it? |
| Location data | We use it, we do not compete on it. | Their core product, with real investment behind it. |
| Signals beyond IP | Email identity, phone, device, repetition, cross-operator graph. | None. IP is the product. |
| Free tier | 10,000 scored events a month. | A free tier for basic lookups, paid tiers for privacy detection. |
| How it is delivered | API, per scored decision. | API and downloadable databases. |
IPinfo is a data company, and a careful one. If your problem is needing to know that 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.
Describing is not deciding#
Their output describes: this address is in Lagos, on this network, operated by this company, and on the right plan, using a VPN.
Ours judges a person: allow, review or block, with the checks that fired and what each one counted for. 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 when you 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.
Network data, and the thing we do differently#
We both surface the network an address belongs to. We use it differently, and this is the closest our products come to overlapping, so it is worth being precise.
Theirs is authoritative registry data: which network 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 comes from our own traffic: how traffic from that network has actually behaved across the operators we score. That is not a fact about the network. It is an observation about our traffic, only possible because we sit on decisions rather than lookups. And it is worth exactly nothing without their kind of data underneath it.
The honest overlap#
Their privacy detection on the higher tiers does overlap with part of what we do. If that is all you need from a risk point of view, 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.
Describing and deciding, 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 that 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 location data 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.
Frequently asked questions
Is IPinfo a competitor to Kaidn?
Barely. IPinfo sells description: this address is in this city, on this network, run by this company. Kaidn sells judgement: allow, review or block, with the checks that fired. The only real overlap is their privacy detection on the higher tiers. If you need to know what an address is, buy theirs. If you need to know what to do about a user, that is a different product.
Do both products use ASN, and is that the same thing?
No, and the difference matters. IPinfo's network data is authoritative registry information: which network an address belongs to and who operates it. That is a fact. Kaidn's network signal is reputational and comes from our own traffic: how traffic from that network has actually behaved across the events we have scored. That is an observation about our traffic, not a fact about the network, and it is worth nothing without registry-grade data underneath it.
How long does it take to build a decision layer on top of an IP feed?
Longer than it looks, and the API call is the smallest part. The build is the weighting between signals, the thresholds, the review queue, the record of what you decided and why, and the six months of tuning afterwards. Teams routinely budget for the integration and not for the tuning, which is where the time actually goes.
Can an IP feed tell me that several accounts belong to one person?
No, and it never will, because that information is not in an IP address. Linking accounts means holding the other accounts: the device that carried them, the real mailbox behind their email addresses, the payout destination they all converge on. An address can hint at it when a farm is careless, and residential proxies are the standard way of no longer being careless.
Which should I buy if I only care about VPN detection?
If VPN or proxy detection is genuinely the whole requirement, one vendor beats two. IPinfo's privacy detection on the higher tiers covers it, and proxycheck.io covers it for a few euros a month. Kaidn is the wrong purchase for that requirement and would cost you more.
