1. The versatile nature of the tool. In a sense, that we can simulate complex scenarios in load tests. 2. Locust is widely used, and so it has an extensive online support group. 3. Ramping up and down the user concurrency is valuable and easy to do. 4. Reports are intuitive.

Its very light and takes less memory as compared to other open source tools like jmeter

Locust has the easiest way I've seen to just load your application and load test it. A simple interface gives different parameters such as number of users and it just runs.
