📡 IP Geolocation API Tester
Run one IP through four independent GeoIP providers at the same time and see, in one screen, where they agree, where they disagree, and which one actually answered fastest.
QUERYING 4 GEOIP PROVIDERS IN PARALLEL...
Why You'd Want to Test a GeoIP API Before Trusting It
Most teams pick a GeoIP provider the way they pick most third-party dependencies: read the landing page, check the free-tier limits, wire it in, move on. That works fine until a support ticket arrives saying a customer in Manchester got routed to the Spanish storefront, or a fraud rule silently waved through a login because the geolocation call returned the wrong country. At that point somebody has to figure out whether the bug is in your integration or in the data the API handed you — and without a second data point, that's a guessing game.
This tool exists to remove the guessing. Enter an IP once and it queries ipwho.is, ipapi.co, geojs.io, and freeipapi.com simultaneously, straight from your browser, then lays every field — country, region, city, coordinates, ISP, ASN, timezone — next to each other in one table. Where all four agree, you can trust the answer. Where they split, you've just found the exact fields worth double-checking before you ship a decision based on them.
🛠️ How This Comparison Actually Works
Click Test APIs and the tool fires four requests in parallel using the browser's native fetch(), each wrapped in an 8-second timeout so one slow provider can't stall the whole comparison. As each response lands, it's normalized into a common shape (country, region, city, latitude, longitude, ISP/org, ASN, timezone) and rendered into two tables: a response-time table showing which provider answered fastest and which timed out or errored, and a field comparison table showing exactly what each one reported. A small MATCH/MISMATCH badge next to every field tells you at a glance whether the providers that responded successfully agree with each other.
Nothing is sent to a ToolsNovaHub server in this process — every request goes directly from your browser to the four GeoIP providers, which is also why this tool can't see or log the IPs you test.
| Provider | Data Style | Typical Free-Tier Limit | Notable Strength |
|---|---|---|---|
| ipwho.is | Geolocation + connection + basic security flags | 10,000/month | Includes ASN and basic proxy/VPN hints without a key |
| ipapi.co | Geolocation + org/ASN | 1,000/day (unauthenticated) | Clean, well-documented JSON schema |
| geojs.io | Geolocation, minimal extras | Unmetered for reasonable use | No key required, generous informal limits |
| freeipapi.com | Geolocation only | 60/minute | Simple response, no ISP/ASN noise if you only need location |
These limits can and do change without notice — always re-verify current terms on the provider's own site before building a production dependency on any of them, free or paid.
🌐 Real-World Scenarios Where API Disagreement Actually Bites
A logistics company built a delivery-zone estimator using a single free GeoIP API for warehouse-partner geolocation. After running a batch of partner IPs through a multi-provider comparison, they discovered one specific /24 block consistently resolved to a neighbouring country in their chosen provider but correctly to the right country in two others — the outlier had been silently misrouting a small percentage of delivery estimates for weeks before anyone traced customer complaints back to that one data source.
📊 Accuracy Expectations by Field
| Field | Typical Cross-Provider Agreement | Why |
|---|---|---|
| Country | Very high (95%+ in practice) | Backed directly by RIR (Regional Internet Registry) allocation records, which are authoritative and rarely ambiguous |
| Region / state | High, with occasional gaps | Depends on how granular the RIR/ISP-submitted data is; large countries with many states see more variance |
| City | Moderate — frequent disagreement | City-level data is inferred, not authoritative, and providers refresh their inference models on different schedules |
| Latitude/longitude | Loosely correlated with city guess | Often just the centroid of the guessed city, so accuracy is bounded by the city guess itself |
| ISP / Organization | High for the network owner, lower for the end customer | Reflects who registered the IP block, not necessarily who's currently routing traffic through it (common with resold/leased ranges) |
