Build resilient systems that perform under any condition

Modern asynchronous architecture with actor-based concurrency. Build sophisticated test scenarios, analyze deep performance insights, and validate system behavior under extreme conditions.

Engineered for how developers
build software

Advanced analytics

DSL-based scripting in Scala, Java, Kotlin, or JavaScript. Version-controlled, maintainable tests integrated into modern DevOps workflows

Code-first testing

Actor-based concurrency with Scala, Akka, and Netty. Simulate tens of thousands of users with minimal resource consumption

Asynchronous architecture

Detailed interactive reports with percentiles, bottleneck analysis, and comprehensive metrics for data-driven optimization decisions

Built for performance engineering excellence

Advanced capabilities designed for performance engineers who need deep control, scalability, and comprehensive analysis

Efficient resource utilization

Actor-based concurrency allows high-scale simulation using far fewer resources than thread-per-user architectures. Optimal performance testing infrastructure.

Integrated assertions

Built-in assertion APIs enforce SLAs, verify error rates, and ensure pass/fail criteria are encoded directly into tests for automated validation.

Distributed load generation

Scale testing across multiple machines or regions. Simulate global user traffic and test applications at massive scale without complex infrastructure setup.

Multi-protocol support

HTTP(S), WebSockets, MQTT, JDBC, and more. Comprehensive protocol coverage for complex application architectures and legacy systems.

Observability Integration

Native integration with Datadog, and other observability stacks. Correlate application and infrastructure metrics during testing.

"With Gatling Enterprise Edition, we can track our performance over time and allow our development teams to automate the scenarios and runs. Gatling enabled us to automate the performance impact assessment of new feature delivery continuously and before releases."
