# Molotov alternatives

> Molotov is an open source, self-hosted protocol and API load tool from Tarek Ziadé, scripted in Python. Teams look for Molotov alternatives when the operating burden, the authoring language, or protocol coverage stops fitting. The closest recorded substitutes are Artillery, Tsung, ghz, Fortio, plus 8 more below — ranked here on license, deployment, scripting and protocols rather than on popularity.

- Baseline: [Molotov](https://perf.jmeter.ai/tools/molotov/)

## Stay with Molotov when
- API and protocol throughput or latency campaigns.
- Teams that prefer open-source licensing and self-hosting options.
- Groups comfortable scripting in Python.

## Switch when
- Teams unwilling to operate generators, results storage, and scaling.
- You need a vendor contract and support path: LoadRunner Professional is sold commercially.
- Your protocol list runs past Molotov: Artillery also records WebSocket, Socket.IO, MQTT.
- The team would rather author in JavaScript, TypeScript: that is Artillery.
