React Usage Statistics
How fast has React grown? React went from a handful of detected domains in 2013 to over 4.7 million active domains by April 2025, making it the most widely deployed frontend library we track. The sharpest growth came during 2020-2021, when active domains jumped from 67,000 to over 600,000 as companies accelerated their web application investments. A second surge in early 2024 brought the library past 3.6 million active domains in a single quarter. Recent months show a pullback to 3.6M active domains by July 2025, likely reflecting broader crawl coverage normalization rather than actual churn.

Expert Analysis: React Growth Trends & Key Signals for Sales Teams in 2026
Let me break down what our technographic data actually shows about React's adoption and customer profile.
1. Growth Trajectory: From Open Source Project to 5.3 Million Domains
React's growth curve is one of the most dramatic in web technology history. Meta open-sourced React at JSConf US in May 2013, and our detection data shows the library went from 4 domains in early 2013 to over 4.7 million active domains by April 2025. The growth trajectory had three distinct phases. From 2014 to 2019, adoption climbed steadily to about 65,000 domains. Then 2020-2021 saw explosive growth, driven by pandemic-era digital transformation and the maturation of tools like Create React App and Next.js. The third phase started in early 2024 when our expanded crawl scope pushed detections past 3.6 million in a single month. Even with recent normalization, React's footprint remains unmatched in the frontend space.
Sales Signal: The addressable market for React-related services and tooling is massive and still expanding. Companies with 3+ year-old React codebases are prime targets for upgrade consulting, performance refinement, and migration to newer patterns like React Server Components.
2. Customer Profile: Small Teams, Big Reach
Our enriched data reveals a customer base that skews heavily toward small teams. 81.6% of React users have 1-10 employees, and adding the 11-50 range brings that to 91.7%. These aren't just hobbyist projects: Software Development (4.23%), Business Consulting (4.09%), and IT Services (3.63%) are the top industries, meaning most React users are professional developers building products or delivering client work. The age distribution reinforces this picture: 41.9% of companies were founded in the 2010s and 32.7% in the 2020s, making three-quarters of the customer base digital-native businesses less than 15 years old.
The enterprise story is different but notable. Companies like Amazon, IBM, Accenture, Deloitte, McDonald's, Infosys, and PwC all run React in production. These firms use React for internal tools, partner portals, career sites, and customer-facing applications. That mix of startup agility and enterprise scale is what makes React's customer base unique.
Sales Signal: Small React shops (1-10 employees) in consulting and IT services are likely freelancers or agencies building React apps for clients. They need dev tools, hosting, CI/CD pipelines, and component libraries. Enterprise React teams need different things: design systems, testing infrastructure, and performance monitoring at scale.
3. Industry and Geographic Concentration
React's industry distribution is remarkably flat. No single industry exceeds 4.3%, with Software Development, Business Consulting, IT Services, Retail, and Technology rounding out the top five. This makes React one of the most genuinely horizontal technologies we track. Compare this to Shopify, where retail-adjacent verticals account for 35%+ of the user base.
Geographically, the United States leads with 36.4% of enriched companies (95,832), followed by the UK (8.4%) and Brazil (4.1%). India (3.9%) and Australia (3.6%) complete the top five. English-speaking markets account for about 52% of the enriched company base, which is notably lower than the 78%+ we see for platforms like Shopify. Brazil's strong showing at 10,839 companies reflects the country's active developer community and growing tech sector.
Sales Signal: React's flat industry distribution means prospecting should focus on company size, tech stack composition, and geographic clusters rather than vertical targeting. Brazil and India are underserved markets with strong React adoption, meaning localized tooling and regional partnerships could capture share.
4. Migration Patterns: React Is a Net Gainer from Legacy Frameworks
React's migration data tells a clear story of legacy framework displacement. The largest gains come from RequireJS (24,560 companies), GSAP (22,829), and AngularJS (13,111). These are older libraries that companies are actively replacing with React. Against Vue, the flow is more balanced: React gained 9,168 companies from Vue while losing 7,094, a 1.3:1 ratio. The Vue v2 to React migration is particularly active in the last year, with 1,412 companies switching as Vue 2 reached end-of-life.
Losses to competitors are modest. React lost 6,872 companies to GSAP and 3,887 to Handlebars, but these likely represent animation and templating additions rather than full React replacements.
Sales Signal: Companies still running AngularJS or RequireJS are high-value migration targets. The Vue v2 to React migration wave is accelerating as Vue 2 support ended. Sales teams can identify these companies on TechnologyChecker.io and pitch React migration services with data-backed urgency.
5. Technology stack: What React Sites Run Alongside
The tech stack overlap data reveals what a typical React-powered website looks like. core-js (59.3%) is the most common co-occurring library, reflecting React's need for JavaScript polyfills in production. jQuery appears on 47.6% of React sites, a number that surprises many developers but makes sense: large organizations added React to existing jQuery applications incrementally rather than rewriting everything.
Google Cloud (36.4%) and Amazon AWS (41.5%) are the top cloud providers, with Cloudflare (29.9%) providing CDN and security. For analytics, Google Tag Manager (48.1%) and Google Analytics (44.8%) dominate. The Facebook network is deeply embedded: 65.2% of React sites integrate Facebook, and 43.1% use LinkedIn for social connectivity.
Sales Signal: The 47.6% jQuery overlap represents a massive modernization opportunity. Companies running both React and jQuery likely have technical debt that needs addressing. Sentry at 37.2% adoption suggests React teams care about error monitoring, but 62.8% don't have it, making error tracking a clear upsell.
Key Takeaways
React's data paints a picture of a library that has won the frontend framework war decisively. With 5.3M detected domains, a 69.7% category share, and net-positive migration from every legacy framework, React's position is secure for the foreseeable future. The customer base is overwhelmingly small, digital-native businesses (81.6% with 1-10 employees, 74.6% founded after 2010), but enterprise adoption from firms like Amazon, IBM, and Deloitte gives the community credibility and scale. The flat industry distribution and global geographic spread make React a genuinely horizontal technology, unlike vertical-focused platforms.

React remains the most widely used frontend library in 2026. TechnologyChecker.io detects it on over 5.2 million active domains, and the library holds a 69.7% share of the JavaScript Frameworks market. The React Compiler reached v1.0 in late 2025, and React Server Components are driving renewed adoption through frameworks like Next.js.
Will AI replace React developers?
AI tools are changing how React code gets written, but they aren't replacing React developers. AI acts as a productivity accelerator for routine code generation, while developers still handle architecture decisions, performance enhancement, and business logic. Companies with 5.2M+ React deployments still need engineers who understand component patterns, state management, and rendering strategies.
What are the advantages of React over Vue?
React offers a larger platform, more job opportunities, and stronger enterprise adoption. Our data shows React on 5.2 million domains versus Vue's 483,858. React also benefits from Meta's ongoing investment and a wider selection of third-party libraries. Vue is often preferred for smaller projects due to its simpler learning curve and built-in features like directives.
Is React more difficult than Vue?
React has a steeper initial learning curve because it uses JSX (a syntax that mixes HTML and JavaScript) and requires more decisions about state management and routing. Vue provides more built-in conventions and HTML-based templates. However, our data shows React's environment is 10x larger by domain count, meaning more tutorials, libraries, and community support are available.
Is React JS obsolete?
No, react is the dominant frontend library with 5.2 million active domain detections and growing enterprise adoption. While newer tools like Svelte and Solid attract attention, React's network, community, and Meta's continued investment keep it the industry standard. Billions of lines of production React code ensure long-term demand for the library and its developers.
Is NextJS replacing React?
Next.js is built on React, not a replacement for it. Next.js is a framework that adds server-side rendering, static generation, and routing on top of the React library. Companies adopting Next.js are still using React for their component layer. The two technologies complement each other, and Next.js adoption actually drives more React usage.
Which big companies use React?
Based on TechnologyChecker.io detection data, large companies using React include Amazon, IBM, Accenture, Deloitte, McDonald's, Infosys, Cognizant, Capgemini, and PwC. All nine have 10,001+ employees. Most deploy React for internal tools, career portals, partner platforms, and customer-facing web applications rather than simple marketing pages.
What industries use React the most?
Software Development leads at 4.23%, followed by Business Consulting (4.09%), IT Services (3.63%), and Retail (3.37%), based on our analysis of 74,819 enriched companies. React's industry distribution is remarkably flat with no single industry exceeding 4.3%, making it one of the most horizontal technologies we track across all categories.
Why are some companies moving away from React?
Some teams cite React's complexity, frequent API changes, and the overhead of managing state in large applications. Our migration data shows React lost 7,094 companies to Vue and 6,872 to GSAP. However, React gains outpace losses across all competitors: 24,560 gained from RequireJS, 13,111 from AngularJS, and 9,168 from Vue, resulting in strong net-positive migration.
Can I learn React in 3 days?
You can grasp React fundamentals (components, props, useState) in a few days with focused effort. Becoming productive enough for real projects typically takes 4-8 weeks of consistent practice. Mastering advanced patterns like custom hooks, React Server Components, and performance tuning requires months. The 5.2M+ domains using React mean abundant learning resources exist.
Is React free for commercial use?
Yes, react is open-source software released under the MIT License, which permits free commercial use without restrictions. Meta maintains the project and contributes engineering resources, but there are no licensing fees, usage limits, or paid tiers. The entire React community including React DOM and React Native is freely available.
What is the difference between React and React Native?
React builds web user interfaces that run in browsers, while React Native creates native mobile apps for iOS and Android. Both share the same component model and JavaScript foundation, but React Native renders to native platform components instead of HTML. Companies like Instagram and Facebook use React for web and React Native for mobile apps.
