Flexible test creation,
your way
Create powerful load tests effortlessly, tailored for every team. From developers and QA
to hybrid testing groups. Gatling's versatile test creation adapts seamlessly to your workflow, not the other way around.
Choose your perfect approach
Code-first power
Write, version, and run load tests in your primary language, JavaScript/TypeScript, Java, Scala, or Kotlin.
Fine-tune logic, model realistic user journeys, and integrate seamlessly into your CI/CD pipelines with full traceability and code reusability.
Low-code speed
Accelerate test creation with the HTTP Recorder and Postman integration.
Capture real user journeys or import existing API collections, then refine scripts with Gatling’s SDKs for advanced logic.
No-code simplicity
Build and launch tests in minutes with the visual test builder.
Configure scenarios, injection profiles, and acceptance criteria, no coding required, with the option to export scripts for later customization.

Gatling SDK’s
Precise performance modeling at code speed
With Gatling, your entire load testing strategy becomes code you control: flexible, versioned, and endlessly customizable.
Design every aspect of your load tests using Gatling’s powerful SDKs for Java, Scala, Kotlin, JavaScript, and TypeScript.
Custom scenarios
Build rich user journeys with full control over flow, data, loops, conditions, and error handling
Flexible load models
Define open (arrival rate) or closed (concurrency) workload patterns, combine phases, or generate complex traffic curves
Dynamic checks
Validate response payloads, extract session data, chain requests, using JSONPath, XPath, JMESPath, regex, and more
Performance assertions
Set pass/fail thresholds on latency, success rate, or throughput, per scenario or globally
Load test any stack, any protocol
Gatling adapts to your tech stack, letting you design load tests for every type of system and architecture.
Web applications and APIs
Ideal for full-stack load testing: HTTP, HTTPS, HTTP/2, WebSocket, REST, GraphQL
Microservices
Perfect for modern service-based architectures: gRPC, JMS, Kafka
IoT and messaging systems
Designed for distributed, event-driven environments: MQTT, Kafka
Databases
Identify and fix bottlenecks in query execution: JDBC
LLM and streaming APIs
