Companies Using React

I run the systems that decide when a page counts as React, so I'll start where most React customer lists don't: with what our rule sees. As of our October 2026 crawl, TechnologyChecker.io counts React on 2,511,466 domains after removing 465,735 parked, for-sale and dead ones, and 1,583,214 of them match a company record. That puts React first of 69 technologies in JavaScript Frameworks with a 35.1% share. It does not mean 2,511,466 teams chose React.

What our React signal sees

A domain counts when a page exposes React's version on a global React object, attaches React's older root container to the page body, or loads a script file named after React. I had 596 random domains from the uncleaned count opened in a browser on 19 October. 440 were working sites running React, and 382 of those had loaded it as a standalone script that sets the global object. That is how site builders ship React. Modern applications bundle it out of sight: of 882,578 domains where we detect Next.js (GoDaddy for-sale pages left out), only 99,812 (11.3%) carry our React marker.

Sales signal: a React detection says a lot about a site's builder and little about its engineering team. If you sell to React developers, start from Next.js, React Router or the company list, not from the headline count.

Two builders carry the count

Wix runs on 49.11% of the clean React domains and GoDaddy Website Builder on 23.02%. Only 404 run both, so together they are 72.11%, about seven in ten. On 206 of the 207 working Wix pages in our sample, Wix's own files loaded React, React DOM, Lodash and core-js from its static.parastorage.com host. Another 3.92% carry other GoDaddy signals without its builder, and 10.61% are WordPress sites without either builder, where React usually arrives as the copy WordPress bundles when a plugin or block asks for it.

Sales signal: segment any React export by builder first. A Wix or GoDaddy row is a small business with a hosted site. A row with neither, or with Next.js, is the prospect for developer tooling.

Growth trajectory: one clean month

The chart holds a single point, 2,511,466 in October 2026, because that is the first month counted after the removal. Earlier React figures aren't comparable with it. Counts are not a like-for-like series over time: the set of domains we crawl turns over every month, with dead sites dropping out and newly found ones added, and our detection signals change over time too.

"React's headline count is mostly a map of website builders. For engineering demand, watch Next.js and React Router instead, because our React signal sees only about one in nine Next.js sites." - David Thomson, CTO at TechnologyChecker.io

Sales signal: don't time outreach off this chart. Time it off releases and advisories: the React team shipped React 19.3 on 9 September 2026, and its December 2025 security advisory for React Server Components asked teams to upgrade immediately.

What we removed, and what's left

Before counting, we removed 211,321 GoDaddy parking pages, 192,845 Wix domains showing Wix's "this domain isn't connected to a site" error, 35,530 GoDaddy for-sale pages and 9,050 Alibaba storefront subdomains. All of them load React, which is why they were in the count. In our sample, those fingerprints took out 96 of 596 domains, and only one of the 96 was a working site. Some dead rows remain. Of the 500 sample domains left, 37 (7.4%) still showed no working site, mostly 14 Wix domains disconnected since our last visit and 13 whose DNS or server no longer answers.

Sales signal: budget for about one dead row in 14, and check the homepage before a sequence goes out. Wix's error page is easy to spot in a quick fetch.

Customer profile

Size and age follow the builders. 74.59% of matched companies with a known headcount have 1 to 10 staff, 92.75% have 50 or fewer, and 70.25% were founded in 2010 or later. The enterprise tail is small, 1,911 companies above 10,000 employees, but its React pages are real applications. IBM's community site, Siemens' events site, Citigroup's global site, DHL's MySupplyChain portal and Nike's store all rendered through React when I opened them. Many enterprise rows are a portal or subdomain, not the main site.

Sales signal: enterprise React work tends to live in one property, such as a careers site, a customer portal or a regional site. Prospect the team that owns that property, not the corporate web team.

Industry and geography

Business Consulting and Services leads at 4.42%, Construction follows at 4.3%, and Software Development misses the top ten. The United States holds 38.1% of matched companies (603,211), the United Kingdom 8.9% and Brazil 4.7%, and the four English-speaking countries in the top five add up to 55.5%. Both lists read like the customer base of two hosted site builders.

Sales signal: for agencies selling rebuilds, trades and local services on Wix are the volume. For developer tools, filter out builder domains first, then weight by industry.

Migration patterns

There's no switching table on this page, and that is deliberate. When I re-checked the 34,215 domains that had lost React while keeping Vue.js, 23,190 (67.8%) had lost other page-head signals, such as Open Graph tags, within a day of losing React, and 18,033 (52.7%) did so in two short windows in August and September. The Svelte, Alpine.js, Angular and AngularJS rows failed the same test, and a row like "from React Router" can't be a switch at all, since React Router only runs inside React. Sites don't strip their meta tags in bulk on one day, so most of these drops are a change in what our crawl reads, not sites leaving React. We removed every React migration row.

"When most of the domains that drop React lose their page-head tags on the same day, the drop measures our crawl, not the market. That's why React's page has no migration table." - David Thomson, CTO at TechnologyChecker.io

Sales signal: don't build a "leaving React" list from churn. 31,742 domains run React and Vue.js together today; those mixed sites are a better list for consolidation pitches.

Technology stack

On the 2,511,435 clean live domains, Cloudflare runs on 47.31%, Google Analytics on 34.45% and Google Cloud CDN on 27.13%. Lodash (76.01%) is there mostly because Wix loads it. Developer frameworks are scarce (Next.js 3.63%, Express 0.8%, Ruby on Rails 0.7%), which I read as one more view of how little modern React our signal reaches.

Sales signal: analytics and security vendors can treat this base as small-business sites, with Google Analytics on about a third. Developer-tool vendors should build lists from Next.js and React Router instead.

Review signals

TrustRadius reviewers praise React's reusable component model most often, and two complaints tie at the top with 7 mentions each: the learning curve, and React being "overkill for simple or static sites". Our data puts a number on the second. Most React domains in our count are small-business sites of that kind, and their owners didn't pick React. Their builder did.

Sales signal: don't pitch React expertise to a Wix customer. Pitch the outcome, a faster site or a working booking flow.

Key takeaways

1. React is #1 of 69 in JavaScript Frameworks with 35.1% and 2,511,466 domains, 2.4 times Vue.js.
2. Seven in ten of those domains are Wix or GoDaddy Website Builder sites.
3. The count misses most modern React: 11.3% of Next.js domains carry our marker.
4. We removed 465,735 parked, for-sale and dead domains; about one in 14 of the rest is still dead.
5. We publish no React migration table: recent drops mostly reflect changes in what our crawl reads.

Sales applications

Outreach template: "Hi [Name], your team's [portal or careers site] at [detection URL] runs React. We help [industry] teams with [specific problem] in React apps like that one. Worth 15 minutes?"

Targeting strategy: on TechnologyChecker.io, take React domains, remove Wix and GoDaddy Website Builder, keep companies with 51 or more employees, then add Next.js or React Router as a second filter.

Competitive angle: the 31,742 domains running React and Vue.js together are mixed codebases, the warmest list for consolidation or migration services.

The full React dataset on TechnologyChecker.io covers 2,511,466 domains and 1,583,214 matched companies, with each row's detection URL so you can check the page before you reach out.
