htmx vs React — Hypermedia vs SPA in 2026
Quick Answer
htmx lets you add AJAX, CSS transitions, and WebSocket support to HTML with attributes — no JavaScript required. React is a full UI library for building complex SPAs. htmx is simpler for server-rendered apps; React is better for highly interactive UIs.
htmx vs React — Side by Side
| Feature | htmx | React |
|---|---|---|
| Approach | HTML attributes (hx-get, hx-post, hx-swap) | JavaScript components (JSX) |
| Bundle Size | ~14KB (no build step needed) | ~45KB (React + ReactDOM min+gzip) |
| Build Step | None — include via CDN or npm | Required (Webpack, Vite, etc.) |
| Server Rendering | Server returns HTML fragments | Server returns JSON, client renders |
| Complexity | Very low — HTML + server templates | High — state management, hooks, effects |
| Interactivity | Limited to AJAX + swapping HTML | Full — complex interactive UIs |
| SEO | Excellent — server-rendered HTML | Requires SSR/SSG for good SEO |
Verdict
Choose htmx for server-rendered applications that need sprinkles of interactivity without JavaScript complexity. Choose React for complex, highly interactive UIs like dashboards, real-time collaboration tools, or SPA-heavy products.
