GATLING VS JMETER
The developer-centric upgrade without compromise
JMeter was built for a different era when just a “testing tool” was needed. Gatling is built for the way engineering teams ship today - code-native, integration-ready, AI-powered and built for scale.
Stop maintaining legacy GUI-based tests. Start trusting performance results and make them visible to engineering leaders. The last migration you'll thank yourself for.
A Legacy Test Tool
vs a Continuous Performance Intelligence Platform
Configuration-based tools made sense before CI/CD. Code-native load testing is how modern engineering teams ship with confidence.
JMeter
A testing tool from another era. Your QA's tool, not your team's tool.
Gatling
Performance testing reimagined for how teams build today.
Tests stored as XML, no IDE support
Resource-intensive
at scale
Modern protocols depend on third-party plugins
CI/CD integration requires manual setup
Code-first: Java, JavaScript, TypeScript, Scala, Kotlin
Async engine: millions of Virtual Users on a single machine
Every modern protocol
built in
Native CI/CD integration: GitHub Actions, GitLab, Jenkins, and more
FEATURE HIGHLIGHT
Reduce risk with Gatling.
Welcome to Continuous Performance Intelligence.
Beyond being a robust, modern alternative to JMeter, Gatling offers a complete performance engineering stack for developers, QA, and SRE teams.
AI capabilities
Automated run summaries surface what went wrong without manual analysis. IDE integration, MCP server support, and a JMeter converter bring load testing into the workflows your engineers already use, including the ones still running JMeter scripts.
SLOs and compliance scoring
Define response time and error rate targets directly in Gatling Enterprise Edition. Every run returns a compliance score, not a pass/fail, a precise percentage. JMeter has no equivalent. Know exactly how long your system held the line.
Test as code
Write load test scenarios in Java, JavaScript or Scala. Versioned, reviewed, and living in the same repository as your application. Plug directly into your CI/CD pipeline. No XML. No GUI workarounds.
Performance trends across every release
Track how your system performs over time, not just in isolation. Compare runs, catch regressions before they reach production, and build an auditable performance record. The visibility JMeter never gave you.

Why engineering teams
switch to Gatling
This year we rewrote our simulations in JavaScript so the whole team could really take ownership. It’s the most accessible language for our developers; and in e-commerce, we use it every day.
Compared to other options, Gatling Enterprise Edition has helped us streamline performance testing in JS. It gave us visibility into key metrics we can now measure and improve, which helps us enhance our product for our customers.
Before Gatling, going live felt like crossing our fingers and hoping it held. Now we can simulate, measure, and move forward with clarity.

Compared to other options, Gatling Enterprise Edition has helped us streamline performance testing with JS. It gave us visibility into key metrics we can now measure and improve, which helps us enhance our product for our customers.
We had to create and maintain our own infrastructure to run JMeter and ghz. With Enterprise, that's handled for us, which saves a lot of engineering time.
We were using homegrown or open-source solutions that were hard to maintain. That pushed performance testing to the back burner; it only ran when absolutely necessary.
Gatling Enterprise has been a game-changer for our performance testing. The ability to simulate real-world loads and automatically test our platform’s response to high traffic has ensured that we maintain top performance, even as our business grows.
Run comparison is a big one. We used to export CSVs and graphs by hand. Now we compare runs directly and get useful insights in real time.
Gatling has become an integral part of our CI/CD pipeline. We run daily load tests, ensuring every change is stress-tested before it reaches production.
