## What it is
rari is a React Server Components framework whose HTTP server, RSC renderer, and router run on a Rust runtime with embedded V8, instead of Node.js. It includes an app router, server actions, streaming SSR with Suspense, and a Rolldown-powered Vite build toolchain with zero-config setup.

## Use cases
- build a react server components app with faster response times than next.js
- streaming ssr with suspense boundaries
- zero-config react framework setup
- file-based routing with layouts and loading states
- server actions and data mutations in react
- add rsc support to an existing vite react project

## When to choose
- you want next.js-style RSC development with much higher throughput and lower latency
- you prefer zero-config setup and standard node_modules/npm resolution
- you want a Rust-powered runtime while writing standard React and TypeScript

## When to avoid
- you need the mature ecosystem, plugins, and battle-tested stability of Next.js
- your deployment relies on Node.js-specific tooling or platforms
- you need a long-proven framework for critical production workloads
