> A high-performance Node.js framework built for speed and developer experience.

## Built for performance

Fastify is a web framework for Node.js that prioritizes speed and efficiency. It's built on top of the `http` module but adds powerful routing, validation, and serialization with minimal overhead.

## Express vs Fastify

Express is like a general-purpose toolbox; Fastify is like a finely-tuned race car engine. Both do the job, but Fastify is optimized for throughput and latency from the ground up.

## Where Fastify shines

High-traffic APIs, microservices, real-time applications, and serverless functions. Fastify's request/reply object pooling and schema validation built-in make it ideal for performance-critical workloads.
