- Canonical: https://perf.jmeter.ai/alternatives/loaderio/
- Baseline: [Loader.io](https://perf.jmeter.ai/tools/loaderio/)

## Stay with Loader.io when
- Teams that want managed load generation without operating injectors.
- Teams that want a free tier before committing to paid capacity.
- Groups comfortable scripting in None.

## Switch when
- Strictly air-gapped environments with no approved cloud path.
- Budget is the constraint: AWS Distributed Load Testing covers overlapping ground under an open-source license.
- You need a vendor contract and support path: BlazeMeter is sold commercially.
- Data has to stay inside your perimeter: Apache JMeter is self-hosted.
- Your protocol list runs past Loader.io: BlazeMeter also records WebSocket, JDBC.
