Locust vs RedLine13: What are the differences?

Developers describe Locust as "Define user behaviour with Python code, and swarm your system with millions of simultaneous users". Locust is an easy-to-use, distributed, user load testing tool. Intended for load testing web sites (or other systems) and figuring out how many concurrent users a system can handle. On the other hand, RedLine13 is detailed as "(Almost) free load and performance testing in the cloud". It is a load testing platform that brings the low cost power of the cloud to JMeter and other open source load testing tools.

Locust and RedLine13 can be categorized as "Load and Performance Testing" tools.

Some of the features offered by Locust are:

• Define user behaviour in code
• Distributed & scalable
• Proven & battle tested

On the other hand, RedLine13 provides the following key features:

• Build packaged, custom, and repeatable tests that can easily delivered to QA, streamlining your testing process
• Run an unlimited amount of tests on an unlimited amount of servers for as long as you’d like. Testing with RedLine13 means testing without limits.
• Cloud load testing means you can scale out your tests: 1,000 users, 100,000 users, and even 1,000,000 users
