Fast and low overhead web framework, for Node.js
Fastify is a fast and low-overhead web framework for Node.js, designed to provide efficient server performance with minimal infrastructure costs and excellent responsiveness under load. Built with JavaScript and inspired by Hapi and Express, Fastify emphasizes high performance—serving over 76,000 requests per second in benchmarks—while maintaining strong developer experience through features like schema-based validation using JSON Schema, extensibility via hooks and plugins, and built-in logging powered by Pino. The project is maintained by a core team including Matteo Collina and Tomas Della Vedova, and is hosted by the OpenJS Foundation as an At-Large Project, with financial support from companies including NearForm and Platformatic.
