Companies Using ipify

I expected ipify to look like the other IP lookup services in our crawl: a developer tool that site owners add on purpose. Mostly it doesn't. Our October 2026 crawl counts a domain when its pages call ipify, which hands back the visitor's public IP address and nothing else. That gives 66,052 live domains, 32,619 matched to a company, 3rd of 66 in Maps & Geolocation. I drew 70 domains at random from the live set and watched each one in a headless browser on 13 October. 45 made the call. The other 25 blocked us, failed to load or stayed quiet for the nine seconds we waited.

Who actually makes the call

For each of the 45, I followed the request back to the script that sent it. 24 came from someone else's code. Five law-firm sites called it through FindLaw's call-tracking script and five Shopify stores through apps: a sales pop-up, a social login, a spin-to-win wheel, Littledata's analytics and Razorpay's checkout. Four used lead-tracking pixels, three a WordPress firewall plugin, and seven more a site platform or widget, including OnCorretor, a Brazilian site builder for insurance brokers. The other 21 called ipify from their own code, seven of them through Google Tag Manager.

FindLaw is the one carrier big enough to move the total. Its scripts load on 4,004 domains in our crawl, and 3,917 of them call ipify, about 6% of the count. The five I opened all used the same Invoca call-tracking account. OnCorretor comes next: 1,933 Brazilian ipify domains carry insurance-broker titles, and 16 of the 18 insurance sites I opened ran its template.

Sales signal: an ipify detection rarely means the owner picked ipify. Read it as a sign that the site runs lead capture, call tracking or a store app that wants the visitor's IP, and segment by the carrier before you pitch.

Growth trajectory

The chart reads 44,426 in June 2026, 58,693 in July, 62,581 in August, 65,315 in September and 66,052 in October. Most of the June to July step of 14,267 is on our side: the domains we crawl turn over every month, with dead sites out and newly found ones in, and our detection widens over time. After July the gains shrink each month, down to 737 in October. 22,983 domains dropped ipify on at least one hostname since we started tracking it on 16 March 2026. On 13 October, 2,809 of the 23,047 then on that list still called it on another hostname.

"Ask who uses ipify and the honest answer is usually somebody's app. The owner installed a store app or a law-firm website package, and ipify came with it." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: treat this as a flat pool of about 66,000 domains. Churn follows the carriers: when a store removes the app that made the call, ipify leaves with it.

Who the customers are

55.72% of matched companies with a known size have 1 to 10 employees, and 80.53% have 50 or fewer. That's a little more small-business-heavy than IPinfo's profile, at 50.2%. There are 853 companies with more than 1,000 staff, and they reach ipify in different ways. Atlas Copco, Fiserv and Wegmans call it from their own site code. Vanguard's adviser site and Capital Group load it through Adobe's tag manager, GAO and Guardian Life through Google Tag Manager. Lenskart and Voltas get it from their cookie-consent scripts, and IQVIA from the checks on its customer-portal login.

Sales signal: at a large company, find the team that owns the property making the call: the adviser portal, the login page, the help centre. That team bought the tool that needs the IP.

Industry and geography

Retail leads at 8.97%, then Insurance (7.07%), Law Practice (6.48%) and Financial Services (4.1%). Add Legal Services (3.32%) and law reaches 9.8%, ahead of retail, which is FindLaw showing through. Insurance is mostly OnCorretor's broker sites. The United States has 15,158 matched companies, then Brazil with 3,940, India 1,656, the United Kingdom 1,407 and the Netherlands 881. Brazil has about 26 companies for every 100 American ones here, against about 17 on IPinfo's profile.

Sales signal: for Portuguese-language outreach, the Brazilian insurance brokers are a ready vertical list, all on one builder. Selling to them means selling through OnCorretor or to it.

Overlap with other lookup services

Our switching table is empty for ipify, and that fits what we see: sites add lookup services next to each other rather than swap one for another. Of the 7,819 domains ever seen with both ipify and IPinfo, 5,296 still run both. With Google Maps the figures are 11,043 and 6,354, and with ipgeolocation 161 and 111. A site running ipify and IPinfo together may be taking the address from one and the location from the other.

"We see no sign of sites leaving ipify for a rival. Two in three sites that ever ran it next to IPinfo still run both, because each answers a different question." - Elif Arslan, CMO & Co-founder at TechnologyChecker.io

Sales signal: for a paid geolocation vendor, the 5,296 domains running ipify and IPinfo together have already shown they want location data, not just an address.

The stack around it

Google Analytics runs on 69.95% of the 65,012 domains in our clean live set, WordPress on 27.1% and Shopify on 25.24%. Cloudflare Browser Insights (15.82%) and Amazon Web Services (14.23%) follow, and WP Engine hosts 8.36%. Invoca is on 7.63%, mostly FindLaw's call tracking again. Next.js sites (7.6%) tend to write the call themselves: in my sample, Wegmans, WM and three smaller Next.js sites did it from their own bundles. ASP.NET is on 7.48% and Adobe Analytics on 9.32%.

Sales signal: filter on the carrier as well as the stack. ipify with Invoca means a law firm, ipify with Shopify means a store app, and ipify with Next.js often means an in-house build. Those are three different conversations.

What it costs

ipify's IP address API is free. Its site says you can use it without limit, that it logs no visitor information and that it's open source. Randall Degges, who built it, wrote on Heroku's blog that it grew past 10,000 requests a second, about 30 billion a month. Calls made from servers never reach a crawler, so our 66,052 is only the browser-side slice. The paid product is the IP Geolocation API: its pricing page lists a free plan of 1,000 credits, then monthly plans from $15 for 10,000 credits and $39 for 300,000 (checked 13 October 2026).

Sales signal: no one on this list pays for the address lookup itself, so there's no contract to displace. A paid geolocation or fraud vendor is selling an upgrade from a free one-field answer.

Key takeaways

1. 66,052 live domains, 3rd of 66 in Maps & Geolocation. Among IP lookup services that puts it ahead of IPinfo (43,583), ipapi.co (41,649) and ip-api (29,663).

2. In our sample, 24 of the 45 calls came from another vendor's code: apps, pixels, plugins and site platforms.

3. FindLaw's call tracking makes the call on 3,917 law-firm sites, about 6% of the count.

4. 55.72% of matched companies have 10 or fewer staff, and Brazil is second by country.

5. 5,296 domains run ipify and IPinfo side by side, and we see no switching between them.

How to use this list

Split the list by carrier first. Filter Law Practice and Legal Services to find the FindLaw group, Shopify for app-driven stores, and Brazil plus Insurance for the OnCorretor brokers. What's left leans towards sites that wrote the call themselves, and that's where a geolocation or fraud vendor has a technical buyer. An opener for that group: "Your site asks ipify for each visitor's IP address. If that feeds fraud checks or routing, we can return the location and risk data in the same call."
