About
Gatling is an industry-leading, AI-powered load testing and performance engineering platform designed for teams who need to uncover performance issues early and at scale. Built on a test-as-code philosophy, Gatling allows engineers to create realistic load simulations using code, a no-code interface, or by importing from Postman — giving every team member a way to contribute. The platform's AI-assisted features accelerate test creation and provide smarter decision-making through intelligent insights and analysis. Gatling integrates deeply into CI/CD and observability workflows, enabling continuous performance testing as a natural part of the software delivery process. Its infrastructure can simulate millions of virtual users and deploy anywhere — on-premises or in the cloud. The platform supports a wide range of use cases including web and internet applications, APIs and microservices, cloud infrastructure, and even AI/LLM performance validation. Available in both a free open-source Community edition and a full-featured Enterprise edition, Gatling serves performance engineers, developers, QA teams, and tech leaders across industries such as finance, retail, broadcasting, and telecommunications. With Gatling Studio, teams can convert browser journeys into full Gatling tests in minutes, making advanced performance testing accessible without deep scripting knowledge.
Key Features
- AI-Assisted Test Creation: Generate and refine load tests faster using AI-powered suggestions, reducing manual scripting effort and accelerating time-to-test.
- Flexible Test Authoring: Create tests your way — via code (Scala, Java, Kotlin), a no-code visual interface, or by importing existing Postman collections.
- CI/CD & Observability Integrations: Plug Gatling into every stage of your pipeline with native integrations for popular CI/CD and monitoring tools for continuous performance validation.
- Scalable Load Generation: Simulate millions of virtual users on-premises or in the cloud, supporting high-concurrency scenarios for enterprise-scale applications.
- Insights & Collaborative Reporting: Analyze performance results smarter with rich dashboards and share insights across teams to drive data-driven decisions.
Use Cases
- Performance testing REST APIs and microservices before production deployment to identify bottlenecks under realistic traffic conditions.
- Integrating continuous load testing into CI/CD pipelines to catch performance regressions automatically on every code change.
- Simulating millions of concurrent users for high-traffic events such as product launches, ticket sales, or streaming broadcasts.
- Validating the performance and scalability of AI and LLM-powered applications under load.
- Enabling QA engineers and non-developers to create and run load tests using the no-code interface or Postman import without scripting knowledge.
Pros
- Open-Source Community Edition: The free, open-source tier provides powerful load testing capabilities with no cost barrier, supported by a large global community.
- Multiple Authoring Modes: Supports code, no-code, and Postman import, making the platform accessible to both developers and non-technical QA engineers.
- Enterprise-Grade Scalability: Can generate millions of virtual users and integrate with enterprise CI/CD pipelines, making it suitable for the most demanding environments.
- Broad Use Case Coverage: Supports testing for web apps, APIs, microservices, cloud infrastructure, and even AI/LLM workloads.
Cons
- Learning Curve for Code-Based Tests: Writing tests in Gatling's DSL (Scala/Java/Kotlin) can be challenging for teams without a strong development background.
- Advanced Features Require Enterprise Plan: Collaboration, advanced analytics, and full AI capabilities are locked behind the paid Enterprise edition.
- Resource-Intensive for Large Tests: Running very large-scale simulations locally requires significant hardware resources; cloud execution may add cost.
