Solid

Solid takes the React mental model — components and JSX — and pairs it with fine-grained reactivity instead of a virtual DOM. Components run once; only the exact pieces of the DOM that depend on changed state update. The payoff is some of the best raw performance in the field, with an API that React developers find immediately familiar.

At a glance

Paradigm

Fine-grained reactivity with JSX. No virtual DOM and no re-rendering — updates are surgical by design.

Language

JavaScript or TypeScript with JSX, close enough to React that the leap is small.

Best for

Interaction-heavy UIs where performance is a priority and the team already thinks in components.

Watch out for

A young ecosystem and small hiring pool. The reactivity rules differ from React in ways that can catch you out.

Why we reach for it

Fast

Fine-grained updates and no diffing put Solid at the top of the performance benchmarks.

Familiar

JSX and a component model mean React developers are productive quickly.

SolidStart

The companion meta-framework adds routing and server rendering for full-stack builds.
