Gatling vs Loader.io: What are the differences?

Introduction

Gatling and Loader.io are both popular tools used for performance testing applications. However, there are key differences between the two that make them suitable for different use cases.

Protocol Support: Gatling has strong support for HTTP protocol and can also handle WebSocket and Server-Sent Events. On the other hand, Loader.io focuses mainly on HTTP and HTTPS protocols, making it more suitable for testing web applications with these protocols.
Scalability: Gatling is more suited for testing complex scenarios and high loads on a single machine due to its intensive CPU utilization. In contrast, Loader.io provides on-demand cloud-based load testing capabilities, allowing for easy scalability by provisioning more virtual users.
Real-Time Monitoring: Loader.io offers real-time monitoring and detailed analytics during the test execution, which can help in understanding the performance of the application under load. Gatling, on the other hand, requires additional integration with monitoring tools for similar real-time insights.
Ease of Use: Loader.io provides a user-friendly interface for creating and managing load tests without the need for scripting or programming knowledge, making it ideal for beginners. Gatling, while powerful, has a steeper learning curve due to its scripting-based test scenarios.
Cost: Gatling is open-source software, making it a cost-effective option for performance testing. Loader.io, being a cloud-based service, comes with a pricing model based on the number of virtual users and test duration, which may incur costs based on the test requirements.

In Summary, Gatling and Loader.io differ in protocol support, scalability, real-time monitoring, ease of use, and cost, catering to different needs in performance testing.

Locust

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.

Flood IO

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!

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
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.
