r/Python on Reddit: Open Source Load Testing with Locust: 13 years, 60 million downloads later

January 24, 2025 -

Hi, maintainer of Locust, the popular load testing tool for Python here 👋

Recently our project turned 13 years old, got its 25,000th GitHub star AND 60 millionth download*, so I figured now might be a good time to look back a little.

In fact, I wrote a whole blog article about it. The TL;DR of it is

* Expressing load tests in Python is still much more powerful than clicking around in a GUI

* Open source is fun, messy and benefits greatly from automated testing

* We're going to do tons of new stuff going forward (AsyncIO, freethreading, extended protocol support). Let me know if you want to contribute! There's also a hosted version nowadays (Locust Cloud)

A big shout out and thanks to the almost 300 people who have contributed so far. You rock.

Let me know if you have any comments on the article or on Locust in general, happy to answer any questions :)

* The truth is that nobody knows how many times Python packages have been downloaded, due to mirrors etc, but at least this one says its 61.3M https://pepy.tech/projects/locust?timeRange=threeMonths&category=version&includeCIDownloads=true&granularity=daily&viewType=chart&versions=2.32.7.dev14%2C2.32.7.dev9%2C2.32.7.dev8

Just wanted to say big thank you for working on this great tool I’ve been using Locust for some time now mainly for HA testing for our clustered application It is much more simpler than using Gatling!

Introduced locust at my last 3 jobs, and it saved my butt each time. Thank you for sharing it.

Installation — Locust 2.43.4 documentation

While Locust itself is a pure Python package, it has some dependencies (e.g. gevent and geventhttpclient) that are compiled from C code. Pretty much all common platforms have binary packages on PyPi, but sometimes there is a new release that doesn’t, or you are running on some exotic platform.
