# TL;DR
* [Fastify](https://github.com/fastify/fastify) is a fast and low overhead web framework for Node.js.
* This package shows how fast it is compared to other JS frameworks: these benchmarks do not pretend to represent a real-world scenario, but they give a **good indication of the framework overhead**.
* The benchmarks are run automatically on GitHub actions, which means they run on virtual hardware that can suffer from the "noisy neighbor" effect; this means that the results can vary.
* For metrics (cold-start) see [metrics.md](./METRICS.md)
# Requirements
To be included in this list, the framework should captivate users' interest. We have identified the following minimal requirements:
- **Ensure active usage**: a minimum of 500 downloads per week
- **Maintain an active repository** with at least one event (comment, issue, PR) in the last month
- The framework must use the **Node.js** HTTP module
# Usage
Clone this repo. Then
```
node ./benchmark [arguments (optional)]
```
#### Arguments
* `-h`: Help on how to use the tool.
* `bench`: Benchmark one or more modules.
* `compare`: Get comparative data for your benchmarks.
> Create benchmark before comparing; `benchmark bench`
> You may also compare all test results, at once, in a single table; `benchmark compare -t`
> You can also extend the comparison table with percentage values based on fastest result; `benchmark compare -p`
# Benchmarks
* __Machine:__ linux x64 | 4 vCPUs | 15.6GB Mem
* __Node:__ `v24.21.0`
* __Run:__ Thu Oct 01 2026 04:08:15 GMT+0000 (Coordinated Universal Time)
* __Method:__ `autocannon -c 100 -d 40 -p 10 localhost:3000` (two rounds; one to warm-up, one to measure)
