Svelte

Svelte compiles your components to vanilla JavaScript at build time — no virtual DOM, no framework runtime shipped to the browser. The result: bundles 50%+ smaller than React equivalents and runtime performance that's hard to beat. Svelte 5's Runes system (`$state`, `$derived`, `$effect`) made reactivity explicit and scalable without losing the simplicity that made Svelte beloved.

React dominates the ecosystem and job market. Vue offers a comfortable middle ground. But for solo devs and small teams where shipping fast matters more than hiring, Svelte's developer experience is genuinely superior — scoped styles by default, less boilerplate, and writing Svelte feels like writing the web.

Use Svelte if you're building a performance-critical app, a solo project, or anything where bundle size matters (mobile web, embedded).

The catch: the ecosystem is young. Fewer UI libraries, fewer plugins, fewer specialized developers than React or Vue. SvelteKit is excellent but the community is a fraction of Next.js's. If you need to hire, React is still the pragmatic default. Svelte is the better tool; React is the safer business decision.
