Vegeta vs Artillery
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- 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.
- 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.
Limitations
- 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.
- Serverless distribution requires AWS knowledge and IAM setup.
- Reporting is basic without exporting to an observability platform.
- Smaller community than k6 or JMeter.
Best for
Backend engineers who want rigorous constant-rate measurements of an endpoint.
AWS-native teams that want large-scale load tests without vendor VU pricing.
