Open source load testing tool and SaaS
for engineering teams
The k6 API and CLI are easy-to-use, flexible and powerful.
Write tests in Javascript that mimic real-world scenarios.
Automate your tests to ensure that your infrastructure and application remain performant.
Configure SLOs in your k6 script to test the health of your services.
Create tests faster with our test builder, recorder or converters (JMeter, Postman, Swagger).
Extensive documentation, awesome community and first class support.
No XML. No DSL. Just familiar scripting with ES6 JS
"The engineering effort of writing tests for just one of our microservices was going to be 2+ Engineering weeks in JMeter, versus the ½ day it took us in k6!"
