ipto vs the alternatives

IP-API.com has run a free, no-signup geolocation API since 2012, and it shows in the polish — sub-50ms responses, five output formats, and a built-in data-correction endpoint.

ipapi.co's trick is a per-field URL pattern — request /8.8.8.8/country/ and get plain text back, no JSON parsing needed.

api.ipify.org is the internet's go-to "what's my IP" endpoint — deliberately minimal, unlimited, and returning nothing but the address itself.

ipregistry leans hard into threat-intel breadth, aggregating 220+ OSINT feeds into categories like attacker, bogon, cloud-provider, and mobile-carrier IPs.

ipgeolocation.io is probably the most feature-complete service in this whole comparison set — modular API, threat scores with confidence and last-seen dates, abuse contacts, a 12-language response, even a separate Astronomy API.

BigDataCloud's standout claim is "no feature gates" — every plan, including free, gets every field; you only pay for volume.

IP2Location.io ships the most granular proxy/threat object in this comparison — thirteen named sub-categories from residential proxy to AI crawler, plus a numeric fraud score.

ipstack advertises "100+ fields" and 2 million+ locations across 200,000+ cities, backed by ISP-partnership data and a 99.9% uptime claim.

ipwhois.io stands out for two unusual fields: a live currency exchange rate (not just a currency code) and a list of each country's bordering nations.

DB-IP, running since 2010, prices by data depth rather than volume: Basic (location only), Core (+ISP), and Extended (+threat data) are three separate price tiers, each also split into Starter/Premium/Enterprise volume bands.

ipbase.com bundles three products under one key: IP geolocation, an ASN lookup API, and a reverse-IP/hosted-domains API that lists every domain pointed at a given address.

IPinfo is the most established brand in this list, with a G2 "#1 for IP Data Accuracy" rating and a 1,000+ point-of-presence measurement network behind its claims.

AbstractAPI's free tier is a genuine standout on one axis — it includes VPN, proxy, Tor, hosting, and abuse detection with a reputation score, which most competitors gate behind a paid plan.

MaxMind has sold IP geolocation since 2002, and its GeoLite2/GeoIP2 databases are the de facto standard several other providers build on top of.

ipapi.is positions itself as a cheaper, higher-quality alternative to IPinfo, and its free tier is a genuine standout: 1,000 requests/day with the same data quality as paid plans, by their own claim — VPN, datacenter, and abuser detection included, not gated behind a paid tier.

ipdata.co offers 1,500 free requests a day with no credit card, plus a distinctive iCloud Private Relay flag most competitors don't call out.

IPLocate.io is one of the more direct IPinfo challengers — it even publishes its own "best IPinfo alternatives" roundup.

ZeroBounce is a dedicated email-verification service built around SMTP-level mailbox checks — connecting to a domain's mail server to test whether a specific address actually exists, not just whether its domain can receive mail.

NumVerify, an apilayer product, validates phone number format and returns country, location, carrier, and line-type data.

IPQualityScore is a dedicated fraud-prevention platform built around per-category depth — IP risk scoring, device fingerprinting that detects emulators and location spoofing, and behavioral bot detection, sold as separate scoring endpoints (IP, email, phone, device, URL) a customer wires together themselves.

LanguageLayer, an apilayer product, detects a text string's language across 173 languages using a tri-gram frequency algorithm — its own FAQ describes checking text against known tri-grams per language, the same underlying technique ipto's Language Detector uses, though LanguageLayer markets the result as "AI-powered." Its free tier caps at 100 requests a month; paid plans start at $4.99/month for 50,000 requests with batch-detection support.

Currencylayer, an apilayer product, covers 168 world currencies with up to 19 years of historical data on its top tier, and update frequency that scales with price — daily on the free plan, all the way to 60-second updates on its $99.99/month Enterprise+ tier.

Weatherstack's free tier returns current conditions only, for 100 calls a month — no forecast, no historical data, and no astronomy fields at that price.

TM Search API mirrors USPTO's own trademark register into a 12M+-record database and markets free-text search across mark name and owner, not just single-serial lookup — no signup required, capped at 20 requests/day per IP, with a $20-per-1,000-calls paid tier settled in crypto on Base Mainnet.

The European Patent Office's Open Patent Services (OPS) — the same API behind the public Espacenet search tool — is free after a developer-account registration, with a fair-use quota of roughly 4GB of data per week before an unlimited paid tier (around €2,800/year) applies.
