React dominates with a 100x larger ecosystem and 300,000+ job listings, while SolidJS delivers 5-10x faster DOM updates through fine-grained reactivity without a virtual DOM. React is the safer choice for most developers; SolidJS excels for performance-critical solo projects.

DOM Update Performance. Ecosystem Size. Job Market Availability. Learning Curve. Community Support. Real DOM Efficiency. Bundle Size (Hello World)
Choose React if you prioritize ecosystem maturity, job market prospects, extensive third-party integrations, and community support—it's the battle-tested standard for teams and complex applications. Choose SolidJS if you're building solo or prioritize cutting-edge performance, smaller bundle sizes, and a modern developer experience without the overhead of virtual DOM reconciliation.

Is SolidJS really 5-10x faster than React?
Yes, benchmarks show SolidJS achieves 5-10x faster DOM updates in real-world applications. This is because SolidJS uses fine-grained reactivity to update only the specific DOM nodes that changed, while React re-renders entire component trees and diffs a virtual DOM. However, React's performance is sufficient for most applications, and the difference only becomes critical in highly interactive or real-time scenarios.
Partially. SolidJS uses JSX syntax familiar to React developers, but the mental model is fundamentally different. React uses component-based state management with hooks and re-renders, while SolidJS uses reactive primitives (signals, effects) with automatic tracking. Expect a 1-2 week learning curve if you're experienced with React, though the core concepts are intuitive.
React is the safer choice for most startups because you can hire experienced React developers (300,000+ job listings) and leverage the massive ecosystem. SolidJS is better if you're a solo founder or small team prioritizing performance and bundle size, or if you have unique real-time performance needs. React's ecosystem advantage often outweighs SolidJS's performance benefits for startups.
Unlikely. React's 100x larger ecosystem, job market dominance, and organizational backing make it the industry standard. SolidJS fills a performance-focused niche for developers and projects that prioritize DX and speed over ecosystem size. Both will coexist—React for general-purpose web development, SolidJS for performance-critical applications.
React. Facebook/Meta actively maintains React with quarterly major releases (React 19 in 2026), extensive documentation, and corporate backing. SolidJS is actively maintained by its creator and community but lacks enterprise-level support infrastructure. For mission-critical applications, React's maturity and backing provide more confidence in long-term viability.
