k6

The best developer experience for load testing. Open source and SaaS for engineering teams. Test early and continuously—break the QA silo in performance testing. Backend and frontend engineers prevent regressions when running performance tests. Test scalability to improve your reliability targets. Test SLOs and avoid SLA breaches. Shift left and collaborate with developers for effective and continuous testing. Use the same script for local, distributed, and cloud tests. Migrate from local tests to the cloud using the same script for both environments. Verify that applications can handle the expected traffic. Adapt your testing: stress tests, peak tests, soak tests, etc. Mix browser and API testing—interact with real browsers and collect frontend metrics to get a holistic user view. Simulate real-world traffic in your chaos experiments. Inject system failures in your k6 tests.
