Flagger

Progressive delivery tool for Kubernetes canary deployments

About Flagger

A progressive delivery tool that automates canary, A/B and blue-green deployments on Kubernetes, analysing metrics from monitoring systems to promote or roll back releases automatically. It is free and open source, so teams can self-host it, inspect the code and adapt it to their own infrastructure without licence fees or vendor lock-in. Typical users run it alongside existing workflows to cut manual effort, improve visibility and keep full control over data, configuration and upgrades over time.
