What is it?

Artillery is a load testing tool for developers and QA teams who need to see how APIs and web services behave under heavy traffic. Tests are defined as scenarios that model user behavior with request chains, multiple steps and transactions, so a test can reflect a realistic user journey rather than a single endpoint being hit repeatedly.

Beyond plain HTTP, it covers WebSocket, Socket.io, gRPC and Kinesis, and it can drive real headless browsers through Playwright to load test front-end flows. It includes integrations for monitoring, observability and CI/CD pipelines, and a plugin API for extending behavior with Node.js modules.

For large tests, load can be distributed across AWS Lambda or AWS Fargate, so the project runs without managing your own load-generation infrastructure. Parts of the code are under MPL 2.0, while certain Azure-specific modules use a BSL license that requires a commercial license for production use.

Key features

  • 01Load test HTTP APIs, WebSocket, Socket.io, and gRPC.
  • 02Run browser-based load tests with Playwright.
  • 03Distribute tests across AWS Lambda or AWS Fargate.
  • 04Model multi-step user flows with request chains and transactions.
  • 05Integrates with 20+ monitoring, observability, and CI/CD tools.
  • 06Extend behavior through a plugin API and Node.js modules.

Use cases

  • Checking whether a REST or GraphQL API holds up under peak traffic before a release.
  • Load testing a web front end's critical user flows with real headless browsers.
  • Running performance regression tests in a CI/CD pipeline.
  • Generating large-scale load from serverless infrastructure without managing servers.

Things to know

  • Some Azure-specific modules are under the BSL license, so commercial or production use on Azure requires a commercial license.
  • Most of the code is MPL 2.0, so the license is a mix of two terms across the repository.
