vpnapi.io Alternatives: Free VPN Detection Compared
vpnapi.io does one job cleanly: send an IP address and get back separate VPN, proxy, Tor and relay flags plus the network’s ASN. A free account covers 1,000 requests a day, and its terms of use license the free version for personal, non-commercial use (both checked on vpnapi.io on 11 October 2026). Teams look for a vpnapi.io alternative when they need a free plan they can use in a business, the name of the VPN service, or a check on the live visit rather than the address alone. This guide compares four options honestly, including where each one is the wrong choice.
Why look for a vpnapi.io alternative?
vpnapi.io is a well-built, narrow tool: VPN, proxy, Tor and relay flags from an IP lookup, with a free daily allowance that covers a lot of small projects. The reasons teams move are mostly about fit. The free licence is personal and non-commercial, so a business needs a paid plan or another provider. We have not seen residential proxy detection or VPN service names documented among its response fields, which matters if your abuse arrives through home connections or you want rules per VPN service. And any IP lookup stops at the address: it says nothing about the browser or device making the request. If none of that applies to you, vpnapi.io may already be the right tool.
What to look for in a replacement
- Residential proxy coverage — not just VPN and datacenter lists
- Device-layer signals (antidetect browsers, automation, tampering)
- A guaranteed request quota rather than a best-effort free tier
- Named signals you can write rules against, with a stable contract
- Latency you can afford inline on signup, login or checkout
- Test tokens or a sandbox so fraud paths can run in CI
Four vpnapi.io alternatives, honestly compared
Maskbreak is a real-time fraud detection API that scores the network and the device of a live visit in one call: residential proxies, VPNs (with the service name when known), Tor and datacenter ranges, plus antidetect browsers, bot automation, emulators and browser tampering. Its bare-IP lookup is narrower: Tor exits and cloud-server ranges only. 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 natural step up if what you want is simply a deeper version of the same lookup: proxy, VPN and Tor flags plus a fraud score, bot status, and optional email and phone validation, with published pricing and a documented free tier. It is broader than vpnapi.io across IP-derived signals. IPQS also lists residential proxy detection among its products; compare the two on your own traffic.
GetIPIntel returns a single probability that an address is a proxy or VPN, and it is free for low volume. If you liked vpnapi.io for its simplicity and cost and just want an alternative in the same spirit, this is the closest match. The trade-offs are the ones that come with a small free service: an email required on each query, informal rather than contractual limits, and no signal breakdown behind the number. See GetIPIntel alternatives.
If the reason you are checking IPs is to decide whether to accept a payment, minFraud fits the job better than any VPN endpoint: it scores the whole transaction using MaxMind's IP intelligence together with email, address and payment heuristics, and integrates with common carts. It is a different product shape — order risk, not an IP boolean — and it is IP-and-data-centric rather than device-centric.
Try the alternative that sees the device too
Maskbreak’s Free plan includes 10,000 visitor checks a month with no credit card; paid plans start at €29 a month. VPN and proxy flags like you have now, plus the device layer that catches what clean IPs hide.
How we verified this comparison
We checked material product and plan claims against first-party documentation on 31 August 2026. We build Maskbreak, so our own product is not a neutral recommendation; verify current limits before choosing a provider.

Frequently Asked Questions
What is the best free vpnapi.io alternative?
Maskbreak’s Free plan includes 10,000 visitor checks a month with no credit card, and each check returns device-layer signals alongside the VPN, proxy and Tor flags you already use. GetIPIntel is the closest match if you want something equally minimal and free. IPQS has a free tier if you want more IP-derived data in the same shape.
Does vpnapi.io detect residential proxies?
We have not seen residential proxy detection documented in vpnapi.io’s API fields, which list VPN, proxy, Tor and relay flags. Residential proxies exit through real consumer ISP connections, so detecting them takes dedicated proxy-network intelligence. Maskbreak reports them on live visits, with the service name when known.
Can I keep the same integration shape?
Partly. IPQS and GetIPIntel accept an IP address and return JSON, so the call site barely changes. Maskbreak’s VPN and proxy verdicts need a browser token collected during the visit, so it fits signup, login and checkout forms rather than log processing; its bare-IP lookup checks Tor exits and cloud-server ranges only. MaxMind minFraud scores a whole transaction rather than an address.
Do I need to talk to sales?
Not for Maskbreak — sign up and call the API, no credit card. IPQS, GetIPIntel and MaxMind are all self-serve too, with MaxMind selling minFraud credits online.
