Companies Using ip-api

We detect ip-api on 29,663 domains, including Sutherland Global, General Mills, Inc., iQor, Inc.. A detection means the technology is present on that domain, which for large organisations is often a single storefront or subdomain rather than a company-wide deployment. Among domains we matched to a company with a resolved industry, the most common is Software Development (12.52%).

We detect 29,663 domains running ip-api across our monthly crawl of live business domains. Company data could be matched for 16,170 of them (54.5%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 10,824 domains carried a ip-api detection previously and no longer do.

ip-api holds 10.27% of the Visitor Identification category, ranking #4. This is a share of the domains we detect running a platform in this category — not a share of all websites, and not a share of spending — so it is not directly comparable to figures published on other denominators.

The top alternatives to ip-api include FingerprintJS (25.81% market share), ipapi.co (14.42% market share), Leadfeeder (12.57% market share), Zoominfo (10.13% market share) — measured as a share of the domains we detect running a platform in this category.

The United States dominates with 9,746 of the companies we can place, more than nine times India in second (1,038), then the United Kingdom (785) and Canada (639). That US concentration is the sharpest difference between ip-api and ipapi.co, which otherwise look like the same product.

49.25% have 10 employees or fewer and 32.2% have 11 to 50. The 45-requests-per-minute cap is generous for a small site and unusable for a busy one, and the size distribution follows that cap almost directly.

41.14% were founded in the 2010s and 31.81% in the 2020s, so nearly three quarters are under 15 years old — the youngest profile in this category. An API you can call without an account tends to get added while a site is being built.

The ideal ip-api customer is: Company Size: 1-10 employees, Industry: Software and ecommerce, Location: United States, Founded: 2010s or later, Use case: Currency and language switching — based on our analysis of 16,170 enriched companies at TechnologyChecker.io.

We detect ip-api on 29,663 active domains as of our August 2026 crawl, fourth in the Visitor Identification category at 10.27%. We match it on the outbound request the page makes to ip-api.com, so the call has to have fired while our crawler had the page open.

The public endpoint is free with no account at all, capped at 45 requests a minute per IP address and HTTP-only on the free tier, with paid plans for HTTPS and higher limits. No signup is the lowest friction in this category, and it shows in both the reach and the churn.

They do the same job on different free tiers: ip-api caps by requests per minute with no account, ipapi.co caps at roughly 1,000 lookups a day. ipapi.co is larger in our data (41,649 domains to 29,663) and more internationally spread, with India close behind the US; ip-api is far more US-concentrated, with 9,746 US companies against 1,038 in India. Despite being direct substitutes, sites essentially never move between them.

No. It returns a location for an IP address and nothing about who the visitor is. The Visitor Identification category mixes IP geolocation with device fingerprinting (FingerprintJS) and B2B company resolution (Leadfeeder, Zoominfo), which are three different products sold to three different buyers. Compare inside a group.

Currency, language and shipping-region selection, mostly. Shopify is on 34.96% of ip-api domains, the highest ecommerce concentration in this category, and Software Development is the top industry at 12.52%. On a storefront an IP lookup is nearly always picking a currency or a regional variant.

More than any other technology on these pages. 10,824 domains have dropped it since March 2026, roughly 36% of the current active base. And they do not turn up on a rival: every candidate destination we tested landed within noise of its base rate, including ipapi.co at 1.71% against 1.46%. The free tier is HTTP-only and rate-limited, so sites hit a wall and remove the call rather than migrate.

Often not. Cloudflare is on 73.12% of ip-api domains, the highest of anything we profiled here, and Cloudflare can pass a visitor's country to the origin in a CF-IPCountry request header as a per-zone setting. A large share of these sites are making a browser round trip for something their CDN could hand the server for free. That is worth knowing before treating this footprint as demand for the service.
