Best GetIPIntel Alternatives in 2026
GetIPIntel returns a single probability that an address is a proxy or VPN, it is genuinely free for low volume, and for a hobby project that is often all you need. Teams usually start looking elsewhere when the constraints bite: an email address required on every query, informal rate limits, no commercial SLA, and a score with no breakdown behind it. This guide compares four options honestly — including where each one is the wrong choice.
Why look for a GetIPIntel alternative?
GetIPIntel is a one-person service that has been quietly useful for years: you pass an IP, you get back a number between 0 and 1. The reasons teams move are rarely about accuracy at the low end. They are commercial and structural — queries require a contact email, the free tier carries informal daily limits that are not contractually guaranteed, there is no DPA or uptime commitment to hand a compliance reviewer, and the response is a bare probability rather than named signals you can write rules against. Teams that need to explain a decision ("blocked: residential proxy + antidetect browser") rather than assert one ("blocked: score 0.99") need something with a documented signal set.
What to look for in a replacement
- Named signals, not just a score — so you can write and defend rules
- A contractual rate limit and uptime commitment, not an informal one
- A DPA you can hand to a compliance reviewer
- Device-layer coverage — residential proxies look clean at the IP layer alone
- Latency you can afford inline on signup, login or checkout
- Test tokens or a sandbox so fraud checks can run in CI
Four GetIPIntel alternatives, honestly compared
Sentinel is a real-time fraud detection API that scores the network and the device in one call: residential proxies, VPNs, Tor and datacenter ranges, plus antidetect browsers, bot automation, emulators and browser tampering across 400+ signals, with a sub-40ms median server decision time behind Cloudflare's edge. Official Node (@sentinelsup/sdk), Python (sentinelsup) and PHP (sentinelsup/sdk) SDKs, deterministic test tokens for CI, and a hosted MCP server so AI agents can screen IPs directly. It does not do email or phone validation.
IPQS is the closest like-for-like replacement: an IP reputation API with a documented free tier, published pricing, and a proxy/VPN/Tor verdict plus a fraud score. Where GetIPIntel gives you one number, IPQS names its signals and adds email and phone validation as separate products. It shares GetIPIntel's structural blind spot — it is reputation-first, so residential proxies on clean home IPs remain hard. See IPQS alternatives if you are comparing that one too.
MaxMind scores whole transactions rather than bare addresses, using its long-running IP intelligence (the GeoIP lineage) plus email, address and payment heuristics. If what you actually want is an order-risk score for a cart or payment flow, that is a different and better-fitting product than an IP probability endpoint. Like GetIPIntel it is data-and-IP-centric rather than device-centric.
Spur specialises in the network layer and is unusually candid about what it sees: VPN operator attribution, residential proxy network identification, and tunnel detection with the operator named rather than implied. If your problem is specifically "which anonymisation service is this and can I trust that classification", Spur's data is excellent. It is network-only by design, so pair it with a device signal if antidetect browsers are in your threat model.

Sentinel is free in open beta — 1,000 API requests per hour, no credit card. Every verdict comes back as named signals, not a bare score.
Frequently Asked Questions
Is GetIPIntel free?
Yes, for low volume. It has long been free for modest query counts with a contact email required on each request, and informal daily limits rather than a contractual quota. That is fine for side projects and awkward for anything with a compliance reviewer or an uptime expectation.
What is the best free GetIPIntel alternative?
Sentinel is free in open beta at 1,000 requests per hour with no credit card and no email required per query, and it returns named signals rather than a single probability. IPQS also has a free tier if you want the closest like-for-like shape.
Why do teams move off GetIPIntel?
Usually commercial rather than technical: no contractual rate limit or uptime commitment, no DPA, an email address required on every query, and a bare probability instead of named signals you can write rules against.
Will any of these catch residential proxies?
Partially, and you should be sceptical of anyone claiming otherwise from the IP alone. Residential proxies exit on real consumer connections, so IP reputation has little to match against. Sentinel and Spur both work the network layer harder than a reputation lookup; Sentinel additionally reads device-layer signals, which is what separates a real customer from an antidetect browser on the same clean address.
