Why Fastify Is the Fastest Node.js Framework: Benchmarks vs Hapi, Express
Fastify, a lightweight Node.js server framework released recently, has quickly gained traction with over 4,800 stars, 30 contributors, and performance benchmarks showing roughly six times Hapi’s speed and 1.5 times Express’s, thanks to fast-json-stringify and find‑my‑way routing, plus a growing plugin ecosystem.
Fastify, a lightweight Node.js server framework recently released, has attracted attention for its impressive performance and growing community.
Despite the maturity of Node.js server frameworks, Fastify has quickly amassed over 4,800 stars, more than 30 contributors, and around 980 commits on GitHub, numbers comparable to early Koa metrics.
The core maintainers, Matteo Collina and Tomas Della Vedova, are well‑known in the Node.js open‑source community; Matteo is a Node.js collaborator and TSC member.
According to the author’s blog, Fastify’s speed advantage comes from its near‑native http.Server() handling of JSON‑based HTTP APIs, delivering performance roughly six times that of Hapi and 1.5 times that of Express, as shown in benchmark graphs.
The framework leverages fast-json-stringify , which serializes JSON about twice as fast as JSON.stringify(), and the find‑my‑way router, whose routing speed is about ten times faster than many other frameworks.
Fastify also offers a growing ecosystem of plugins for template rendering, React, GraphQL, static file serving, and database drivers.
