Open source and free, including distributed runs on your own AWS account. You pay AWS, not Artillery.

• Very high throughput per load generator thanks to the async architecture.
• Code-first scenarios that review, diff and refactor properly.
• The default HTML report is genuinely good enough to hand to a stakeholder.

• Distributed load on your own AWS account, so no per-virtual-user vendor pricing at all.
• Reuses Playwright scripts for browser-level load without rewriting journeys.
• YAML for simple scenarios, JavaScript when you need real logic.

• Historically Scala-first; the Java and JavaScript DSLs are newer and less documented.
• Fewer protocols than JMeter.
• Distributed load without the enterprise product means building your own orchestration.

• Serverless distribution requires AWS knowledge and IAM setup.
• Reporting is basic without exporting to an observability platform.
• Smaller community than k6 or JMeter.

JVM teams wanting code-first performance tests with excellent reporting.

AWS-native teams that want large-scale load tests without vendor VU pricing.
