Use Cases

  • Prepare for traffic surges - run load tests to help prepare your API or service for upcoming peak traffic
  • Run load tests in CI/CD to catch and prevent performance regressions before they cause issues for users
  • Profile and debug performance issues such as memory leaks, high tail latency caused by GC pauses or high CPU usage, or misconfigured resource pools
  • Run smoke tests continuously against production to catch issues (also known as production scripted testing or synthetic monitoring)
  • Designed for modern web APIs, headless CMS and e-commerce systems, IoT backends, real-time services, and microservice architectures
  • Test internal microservices and components as well as external endpoints
  • Scale out and run your tests from your own AWS account with ease


  • Test ANY stack: Load test HTTP, WebSocket,, Kinesis, HLS, and more
  • Scenarios: Support for complex scenarios to test multi-step interactions in your API or web app (great for ecommerce, transactional APIs, game servers etc).
  • Load testing & smoke testing: reuse the same scenario definitions to run performance tests or functional tests on your API or backend.
  • Performance metrics: get detailed performance metrics (latency, requests per second, concurrency, throughput). Track custom metrics with high precision (histograms, counters and rates)
  • Scriptable: write custom logic in JS, using any of the thousands of useful
  • Integrations:
    support out of the box for real-time reporting (integrate with Datadog, Librato, InfluxDB etc).
  • Extensible: write custom reporters, custom plugins, and custom engines, or just customize VU behavior
  • Cloud-native: go from running a test locally to running it in your own AWS account, distributed across geographical regions in minutes with Artillery Pro
  • and more! HTML reports, nice CLI, parameterization with CSV files.

  • Artillery Pro: if you want to scale out your tests and run them from hundreds of nodes, multiple geographic regions, and your own AWS account you're going to love Artillery Pro. Get going in minutes (for real), and avoid reinventing the wheel or building a DIY in-house solution for load testing. Self-hosted and self-service, with support for Fargate and ECS, and ability to plug into existing AWS security, compliance and governance controls in your organization. Drop us a line if that sounds interesting.
  • For training, custom integrations, and performance consulting services see our professional services page.

Plant Some Trees!

We have planted over 1,700 new trees with the help of Artillery community. That's a small forest! We're aiming to grow that to a large forest - we're thinking 100,000 trees would be neat.

If you've enjoyed using Artillery and would like to help us out, add your tree to the forest. 🌲🌳🌴 Feel free to drop us a line to let us know too! 💚
