SolidJS vs React ComparisonReact's JSX, Svelte's reactivity model: but does it matter in practice?
SolidJS is what you get when you take React's syntax and replace its execution model entirely. Components in Solid run once: there are no re-renders. Reactivity comes from signals which track dependencies at a granular level and update only the precise DOM nodes that need changing. The benchmark numbers are real: Solid consistently ranks near the top of the js-framework-benchmark results. For most teams, though, performance is not the bottleneck. Ecosystem is. The developer audience for Solid is specific: engineers who understand React's re-render model deeply enough to find it limiting, and who are building something where that limitation genuinely matters.
Head-to-head summary
Detailed comparison
Our verdict
SolidJS is technically impressive: fine-grained reactivity without the virtual DOM is a genuinely superior execution model in theory. But for almost every real project, React wins on ecosystem, hiring, and community knowledge.
When to choose each
Choose SolidJS when:
- You're building a highly interactive, performance-critical UI where React's re-render model is a measurable bottleneck
- Your team is small, experienced, and deeply understands React's limitations, not just its syntax
- You're building a long-lived internal tool where ecosystem breadth matters less than runtime efficiency
- You want fine-grained reactivity without adopting a non-JSX template syntax like Svelte
Choose React when:
- You need to hire developers: React's talent pool is orders of magnitude larger than Solid's
- Your project integrates third-party libraries or UI kits that ship React-first
- The team has existing React knowledge and there's no clear performance ceiling being hit
- Long-term maintainability and onboarding new engineers is a priority
