• Zero configuration; useful output in seconds.
• Good percentile reporting for such a small tool.
• Scriptable from Node for micro-benchmarks in CI.

• 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.

• Single endpoint only — no user journeys, no correlation, no think time.
• No distributed execution.
• HTTP/1.1 focused.

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

Quick endpoint benchmarks and micro-optimisation work.

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