VERDICT

Should I use React?

React is the library for web and native user interfaces. Build user interfaces out of individual pieces called components written in JavaScript. - react.dev

Depends. Adopt React if you're a developer team building interactive web or cross-platform apps — it's free, with the largest ecosystem and hiring pool in its category. Skip it if nobody on your team writes code or you just need a content site; plain HTML or a no-code builder is the better fit.

Confidence

Medium. Based on ~12 usable public sources. Many search results were unrelated products sharing the 'React' name (a Welsh funding program, an identity-management tool, CPAP devices), which limits confidence.

Best for

  • Orgs that want the biggest hiring pool
  • Component-driven design systems

Not for

  • Non-coders — it's a code library, not a tool
  • Simple brochure or content sites — plain HTML is easier
  • Teams wanting a batteries-included, opinionated framework
  • Solo builders unwilling to track security patches themselves

Free, open-source UI library and the industry default. Great for interactive apps; overkill for simple sites, useless if nobody codes.
