Performance Testing in CI/CD Pipelines with k6 and Grafana

Speed should not be an afterthought. Integrating performance testing into your CI/CD pipeline catches regressions before they reach production. k6 is an open-source load testing tool designed for developer workflows, written in JavaScript for easy scripting. Combined with Grafana for visualization and Grafana Cloud for historical tracking, you get a complete performance monitoring solution. This topic covers setting up k6 tests that run on every pull request, defining performance budgets that block merges when thresholds are exceeded, and configuring Grafana dashboards to display results alongside build metadata. We discuss how to simulate realistic user journeys, manage test data, handle flaky results, and gradually increase load to find breaking points. Teams that adopt this approach report catching 80 percent of performance regressions before deployment.
