Fastify Has a Free Node.js Framework — 4x Faster Than Express

Fastify handles 60,000+ requests per second on Node.js. Schema-based validation, automatic serialization, and a plugin architecture that doesn't sacrifice speed. Why Not Express? Express is simple but slow. It has no built-in validation, no schema support, no serialization optimization. Every middleware adds overhead. Fastify was designed from day one for performance without compromising developer experience. What You Get for Free import Fastify from ' fastify ' ; const app = Fastify ({ logger : true }); app . get ( ' /user/:id ' , { schema : { params : { type : ' object ' , properties : { id : { type : ' string ' } } }, response : { 200 : { type : ' object ' , properties : { id : { type : ' string ' }, name : { type : ' string ' }, email : { type : ' string ' } } } } } }, async ( request ) => { return getUser ( request . params . id ); }); app . listen ({ port : 3000 }); JSON Schema validation — request validated before your handler runs Fast serialization — response serialized based
