What is React?

React is a JavaScript library for building user interfaces, originally developed at Facebook (now Meta) and open-sourced in 2013. It introduced the component model and virtual DOM that now dominate frontend development, and it remains the foundation under Next.js, Remix, React Native, and most commercial JS frameworks.

React itself is deliberately minimal—state management, routing, data fetching, and SSR all ship as separate libraries or frameworks on top. The 2022–2024 shift to React Server Components changed that balance somewhat, pushing some traditional framework concerns into React proper, though most developers adopt RSC through Next.js rather than directly.

Who uses React?

React powers production UIs at Meta, Netflix, Uber, Shopify, Airbnb, Atlassian, Dropbox, Instagram, WhatsApp, Cloudflare, Vercel, and most modern SaaS companies. It’s the most-listed frontend skill on engineering job boards globally and the dominant choice for new web products outside of a few Vue-heavy ecosystems.

React developers fall into consumers of component libraries (shadcn/ui, Radix, MUI), framework users (Next.js, Remix), React Native developers, and library authors. Each of these segments represents a buyer for tools in their specific workflow—CMS, analytics, payments, auth, design systems.

According to the React README: “React is a JavaScript library for building user interfaces.” (source)

How to reach developers using React

If you sell a tool that integrates with React, complements it, or competes with it, the developers contributing to it are your buyers. They’re the ones evaluating tools in your category right now.

Developers signal interest through GitHub activity—starring, forking, opening issues, submitting pull requests. LeadCognition captures those signals across millions of repositories and enriches each developer with verified work email, LinkedIn URL, and current employer.
