• 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.

• Constant-rate model avoids the coordinated-omission problem that distorts VU-based tools.
• Single static binary, trivial to run anywhere.
• Composable output for scripting and pipelines.

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

• No scenarios or session state — one target list, one rate.
• No GUI or built-in reporting beyond plots.
• Go library usage required for anything sophisticated.

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

Backend engineers who want rigorous constant-rate measurements of an endpoint.
