Baseline tool
When to stay
- API and protocol throughput or latency campaigns.
- Teams that prefer open-source licensing and self-hosting options.
- Groups comfortable scripting in Erlang, XML.
When to consider switching
- 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 Tsung: Artillery also records WebSocket, Socket.IO, MQTT.
- The team would rather author in JavaScript, TypeScript: that is Artillery.
