## At a glance

- **Maintainer**: Svelte core team (backed by Vercel)
- **First release**: 2016
- **Language**: JavaScript / TypeScript
- **License**: MIT

## Learning curve

Gentle, the closest of any framework to plain HTML, CSS and JavaScript; runes in Svelte 5 add a small reactive vocabulary.

## Performance

Compiles the framework away, tiny bundles, no virtual DOM and top-tier runtime speed, especially on low-end devices.

## Ecosystem

Growing but much smaller than React or Vue; SvelteKit covers routing and SSR officially, but niche libraries often need hand-rolling.

## Ideal for

- Performance-critical marketing sites
- Embedded widgets and interactive data visualization
- Small teams that want to ship fast with little boilerplate
- Projects targeting low-end or mobile devices

## Pros

- Smallest bundles and fastest startup of the major frameworks
- Genuinely simple mental model with minimal boilerplate
- SvelteKit provides a complete full-stack story (SSR, routing, endpoints)
- Scoped styles and transitions built into the language

## Cons

- Smallest talent pool and third-party ecosystem of the big four
- Fewer large-scale enterprise case studies
- Some integrations that are trivial in React must be built from scratch
