## At a glance

- **Maintainer**: Vercel
- **First release**: 2016
- **Language**: JavaScript / TypeScript

Moderate, you need React first, and the App Router plus React Server Components add a real extra layer of concepts.

## Performance

Excellent Core Web Vitals when used well, sSR, static generation, ISR, streaming and built-in image and font optimization.

## Ecosystem

The de facto standard React framework with massive adoption; deploys anywhere, though the smoothest experience is on Vercel.

## Ideal for

- SEO-critical marketing and content sites
- E-commerce storefronts
- Full-stack React products with API routes
- Teams standardizing on one React meta-framework

## Pros

- SSR, SSG and ISR built-in, the strongest SEO story in the React world
- File-based routing plus API routes cover full-stack needs in one project
- Automatic image, font and script optimization out of the box
- Server components cut client JavaScript significantly
- Huge adoption, patterns, hires and answers are easy to find

## Cons

- App Router and server components add complexity and have churned quickly
- Some features are tuned for Vercel hosting first
