Gatling vs Loader.io vs Locust: What are the differences?

1. **Protocol Support**: Gatling supports HTTP, WebSockets, and JMS protocols, whereas Loader.io focuses primarily on HTTP and HTTPS protocols and Locust mainly concentrates on HTTP protocol. 2. **Architecture**: Gatling is a Scala-based tool with a high level of concurrency and scalability, Loader.io is a cloud-based load testing service, and Locust is a Python-based load testing tool that allows writing test cases in Python code. 3. **Ease of Use**: Gatling has a steep learning curve due to its complex DSL language, while Loader.io offers a user-friendly interface for quick and easy setup, and Locust provides a simple and intuitive way to write test scenarios using Python code. 4. **Reporting**: Gatling generates detailed and comprehensive reports with graphs and statistics, Loader.io provides basic reports and real-time monitoring, and Locust offers simple HTML reports. 5. **Cost**: Gatling is an open-source tool with no licensing costs, Loader.io offers free and paid plans based on test credits, and Locust is open-source with no licensing fees. 6. **Community Support**: Gatling has a large and active community with extensive documentation and forums, Loader.io has limited community support, and Locust has a growing community and resources.

In Summary, Gatling, Loader.io, and Locust differ in protocol support, architecture, ease of use, reporting capabilities, cost, and community support.

Needs adviceonJenkinsJenkinsGatlingGatlingLocustLocust

I am looking for a performance testing tool that I can use for testing the documents accessed by many users simultaneously. I also want to integrate Jenkins with the performance automation tool. I am not able to decide which shall I choose Gatling or Locust. But for me, Jenkins integration is important. I am looking for suggestions for this scenario.

I have to run a multi-user load test and have test scripts developed in Gatling and Locust.

I am planning to run the tests with Flood IO, as it allows us to create a custom grid. They support Gatling. Did anyone try Locust tests? I would prefer not to use multiple infra providers for running these tests!

Needs advice

I want to do performance testing with HTTP protocol but the test script should be java script. For now, I kept "Artillery" and "K6" tools in my queue. Did you guys have any idea about this? Is there any tools which support Test script language: JavaScript Protocol: Http/web service Must Feature: Record OS: Mac os/windows

Detailed Comparison

Loader.io

Gatling
Gatling
Locust
Locust

Loader.io is a free load testing service that allows you to stress test your web-apps/apis with thousands of concurrent connections.

Gatling is a highly capable load testing tool. It is designed for ease of use, maintainability and high performance. Out of the box, Gatling comes with excellent support of the HTTP protocol that makes it a tool of choice for load testing any HTTP server. As the core engine is actually protocol agnostic, it is perfectly possible to implement support for other protocols. For example, Gatling currently also ships JMS support.

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.
