What reviewers say
Powerful Performance Testing, but Beginners Need a Better GUI
“I like Gatling’s high performance, code-based scripting, and detailed performance metrics. I can simulate realistic user traffic and journeys, control concurrent users, ramp-up rates, and request arrival rates, and use assertions and response-time percentiles to validate performa”
Good tool for performance testing and load testing
“What I like best about Gatling is that it makes performance testing easier to manage and helps identify bottlenecks in an application. I also like that you can write tests as code, reuse scenarios, and integrate them into CI/CD pipelines to automate performance testing.”
Comprehensive Load Testing with Gatling, but Steep Learning Curve
“I like that Gatling allows me to simulate realistic user loads with clear performance metrics, which helps me understand how APIs and workflows perform under stress. I appreciate that creating performance scenarios is easy and repeatable, making it useful for regression testing. ”
