Engineered for how developers
build software

Code-first by design

Write and maintain load tests like you do application code. Test-as-code with JavaScript, TypeScript, Java, Scala or Kotlin.

CI/CD native

Run tests automatically in your pipeline. Enforce SLAs, prevent regressions, and ship with confidence.

Lightweight and scalable

From local laptop runs to distributed cloud tests, Gatling’s engine gives you speed and flexibility, without complex setup.

Built for real engineering workflows

Start testing like you build: In code, in CI, and at scale.

Strategic performance analytics

Infrastructure that scales with you

The best experience for every team

Built for simplicity and speed

Performance testing

Cross-team collaboration

Seamless load testing that speeds your SDLC

Automated performance validation

Run tests at every stage of your CI/CD pipeline. Block underperforming builds and track regressions over time.

Observability and tracing integrations

Correlate test traffic with APM, traces, and metrics. Integrates with Datadog, Dynatrace, and more.

Infrastructure-as-code ready

Deploy and run tests with Kubernetes, Terraform, Docker, or Helm. Spin up reproducible environments for consistent, production-like testing.

Modern protocol support

Choose your flavor: HTTP, WebSocket, gRPC, JMS, GraphQL. Gatling supports the protocols your systems
rely on. Ideal for APIs, service meshes, and real-time services.

Live dashboards and reporting

Visualize real-time test results and trends.Track latency, error rates, throughput, and test health with zero setup.

Common use cases for developer teams

Gatling helps developers build, test, and ship performant systems, from first commit to production readiness.

Microservices load testing

CI/CD performance gates
CI/CD performance gates

Run tests on every PR, commit, or deployment. Fail builds that exceed latency or error thresholds. Track performance trends over time.

Heading

SLO & SLA validation
SLO & SLA validation

Test against latency targets, error rates, and throughput thresholds. Automate enforcement of performance budgets in pipelines.

Load testing with observability
Load testing with observability

Run Gatling to apply realistic traffic and integrate with APM/observability tools to correlate load with backend bottlenecks and detect issues early.

Heading

Pre-release load validation
Pre-release load validation

Run performance tests on new features, releases, or architectural changes in staging or production-like environments.
