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.

I have a team that is not heavy on programming skills. I am looking for a load testing tool that is easy to use. Preferably, the tool should be a record and playback tool without much programming. Also, the tool should be able to test APIs apart from web-based applications. What tool should I opt for?

My choice would be Apache JMeter, It's free and opensource plus it comes with lots of plugins and extendability. Apache JMeter needs a small amount of a learning curve and a basic understanding of Network, Protocols (TCP/IP ports, HTTP(S) and REST/SOAP, etc.) for initial setup. But it doesn't require programming skills. it has a nice record and playback option. You can still carry on without the developer skillset if you follow these steps. 1. Take backup. 2. Start recording and interact with the application. 3. stop recording and save the test case. This will give you your test-bed, after this, after these steps, every time just do Restore from backup and then Playback and observer results.

If you have longer recordings then an understanding of how to modify the recorded scripts will come handy.

For some of the advanced features such as Configuring variables, implementing loops, throttling adding think time, and automating test scaling to the number of users will require good planning of test scenarios and a Developer experience but this is true for any tool (even loader.io)

Disclaimer: I work at k6, and I recommend you try our tool.

It might require some coding skills, but we support a few options to record a user session to autogenerate the load test. Read How to record a browser session with k6 OSS.

The k6 Cloud also supports recording a user session with a Browser Extension. Additionally, it provides a Test Builder UI to generate a load test for testing APIs.

If you have questions or need help, you can ask on Slack and the Community forum.

    What is Gatling?

    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.

    What is Loader.io?

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

    What is Locust?

    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.
