Is SolidJS faster than React?

Yes, in virtually all benchmarks. Solid's fine-grained reactivity updates only changed DOM nodes without virtual DOM overhead. The gap narrows with React concurrent features but Solid remains faster for most operations.

Can I use React libraries with SolidJS?

No. Despite similar JSX syntax, React components and hooks are not compatible with Solid. Solid has its own ecosystem, which is much smaller. Some UI libraries like Kobalte provide Solid-native components.

Should I switch from React to SolidJS?

Only if performance is critical and you can accept a smaller ecosystem. For most applications, React is fast enough and the ecosystem advantage is enormous. SolidJS is a great choice for new projects that prioritize raw performance.

SolidJS vs React — Fine-Grained Reactivity vs Virtual DOM in 2026

Quick Answer

SolidJS uses fine-grained reactivity to update only the exact DOM nodes that change — no virtual DOM diffing. React uses JSX too but relies on virtual DOM reconciliation. Solid is consistently faster in benchmarks but has a much smaller ecosystem.

SolidJS vs React — Side by Side

Feature	SolidJS	React
Reactivity	Fine-grained signals (createSignal)	Virtual DOM diffing (useState)
Re-renders	Components run once, only DOM updates	Components re-run on state change
Bundle Size	~7KB	~6.4KB core + ~40KB ReactDOM
Performance	Consistently top in JS Framework Benchmark	Good, slower on fine-grained updates
JSX	Yes — compiles to real DOM operations	Yes — compiles to virtual DOM calls
Ecosystem	Small — SolidStart meta-framework	Massive — Next.js, thousands of libraries
Community	~33K GitHub stars	228K+ GitHub stars

Verdict

Choose SolidJS for performance-critical applications where you want React-like JSX with true fine-grained reactivity. Choose React for its unmatched ecosystem, job market, and community. SolidJS is technically superior in performance but React wins in adoption.
