Apache JMeter 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.

Open sourceWhat drives the bill
The metric that actually scales your invoice.
Free. Costs are load-generator infrastructure and, commonly, a cloud execution service such as BlazeMeter.
Open source and free, including distributed runs on your own AWS account. You pay AWS, not Artillery.

Strengths
- Protocol coverage no modern tool matches — JDBC, JMS, LDAP, mainframe-adjacent protocols.
- GUI test-plan building is accessible to testers who do not code.
- Enormous body of documentation, plugins and available expertise.
- 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
- Thread-per-user model is memory-hungry; high load needs a cluster where k6 needs one box.
- JMX test plans are XML that merges terribly in version control.
- The GUI must not be used for actual load generation, which trips up nearly every beginner.
- 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
Enterprise performance teams needing protocol breadth and a GUI-based workflow.
AWS-native teams that want large-scale load tests without vendor VU pricing.
