Leveraging our experience with Node.js performance, Fastify has been built from the ground up to be as fast as possible.

All the code used for our benchmarks is available on GitHub.

Here's a brief summary on how Fastify overhead performed against the some other well known Node.js web frameworks:

44984 req/sec


35265 req/sec


10642 req/sec


32902 req/sec


29118 req/sec


Please note that this is a synthetic, "hello world" benchmark that aims to evaluate the framework overhead. The overhead that each framework has on your application depends on your application, you should always benchmark if performance matters to you.
