SolidJS vs Svelte
Two frameworks that rejected the virtual DOM. One compiles away. One uses signals. Both are faster than React.
Svelte
Svelte has a bigger ecosystem, SvelteKit is production-ready, and the DX is unmatched. SolidJS is technically impressive but the ecosystem is still catching up.
The Anti-React Club
Both Solid and Svelte looked at React's virtual DOM and said 'this is unnecessary overhead.' They're both right.
Svelte compiles your components into vanilla JS at build time. No runtime framework. SolidJS uses fine-grained signals — reactive primitives that update only what changed, no diffing.
Why Svelte Wins Today
SvelteKit is a mature, production-ready meta-framework. Routing, SSR, static generation, API routes — it's all there.
The Svelte syntax is the cleanest in the business. {#each items as item} reads like English. Two-way binding with bind:value just works.
The community is large enough that you'll find answers on Stack Overflow. Libraries exist. Jobs are starting to appear.
Why Solid is Technically Better
Solid's reactivity model is more predictable. Signals are explicit — you always know what's reactive and what isn't. Svelte's compiler magic can be surprising.
Solid is faster in benchmarks. Not that it matters for most apps, but if you're building something performance-critical, Solid's signal-based updates are surgically precise.
JSX means your React knowledge transfers. Svelte's template syntax is its own thing.
Quick Comparison
| Factor | SolidJS | Svelte |
|---|---|---|
| Approach | Signals (runtime) | Compiler (no runtime) |
| Syntax | JSX | Custom (.svelte files) |
| Meta-framework | SolidStart (maturing) | SvelteKit (mature) |
| Performance | Fastest | Very fast |
| Ecosystem | Small | Medium, growing |
| Learning Curve | Easy if you know React | Easy for everyone |
| TypeScript | First-class | Good, improving |
The Verdict
Use SolidJS if: You want the fastest possible framework, love signals and fine-grained reactivity, or are coming from React and want JSX.
Use Svelte if: You want the best DX, a mature meta-framework, and a growing ecosystem. SvelteKit is production-ready today.
Consider: React is still the safe choice for jobs and ecosystem. Both Solid and Svelte are bets on the future.
Svelte has a bigger ecosystem, SvelteKit is production-ready, and the DX is unmatched. SolidJS is technically impressive but the ecosystem is still catching up.
