"Powerful and Easy-to-Use Performance Testing Tool"

4/5

What do you like best about Gatling?

UI / UX

The web-based reporting dashboard is crisp, clean, and highly intuitive. Navigating through response time distribution graphs, percentile breakdowns, and transaction metrics requires zero setup, making test results immediately understandable for both technical engineers and management.

Integrations

It integrates seamlessly into modern DevOps pipelines via native plugins for Jenkins, GitLab CI, GitHub Actions, and Maven/Gradle. Running load tests automatically as part of pull request checks or nightlies is effortless and fits right into existing software development workflows.

Performance

Built on Akka and Netty, Gatling uses an asynchronous, non-blocking architecture that allows a single machine to simulate thousands of concurrent users with minimal CPU and memory footprint. You get maximum virtual user throughput without needing a massive distributed infrastructure.

Pricing / ROI

The open-source core provides incredible value for standard protocol load testing without licensing costs. For enterprise teams, Gatling Enterprise offers high ROI by saving engineer hours on distributed execution, historical trend analysis, and team collaboration.

Support / Onboarding

The official documentation is top-notch, packed with clear code examples, DSL quickstarts, and structured tutorials. Combined with an active community forum, onboarding developers—even those new to performance testing—is smooth and straightforward.

AI / Intelligence

With recent enhancements around automated test generation and smart reporting, creating complex simulation scenarios from HAR files or OpenAPI definitions is faster than ever, taking the guesswork out of script maintenance and anomaly detection in test runs.

What do you dislike about Gatling?

The open-source version primarily focuses on HTTP/REST, so if you need out-of-the-box UI/browser-level testing or uncommon non-HTTP protocols, you may need additional plugins or extensions. Otherwise, for API and microservices performance testing, it covers almost everything you need. Review collected by and hosted on G2.com.

What problems is Gatling solving and how is that benefiting you?

Gatling helps simplify performance and load testing by making it easy to create realistic user scenarios and execute tests at scale. It provides clear performance metrics and helps identify bottlenecks, response-time issues, and system capacity limitations. This makes it easier for our team to validate application performance, detect issues early, and make data-driven improvements before production. Review collected by and hosted on G2.com.
