Argo Rollouts Has a Free API — Progressive Delivery for Kubernetes

Argo Rollouts is a Kubernetes controller that provides advanced deployment strategies — canary releases, blue-green deployments, and progressive delivery with automated analysis. Free, open source, CNCF project. Works alongside ArgoCD or standalone. Why Use Argo Rollouts? Canary deployments — route 5% of traffic to new version, auto-promote if metrics pass Blue-green — instant rollback by switching services Analysis runs — automated rollback based on Prometheus, Datadog, or custom metrics Traffic management — integrates with Istio, Nginx, ALB, and Traefik Quick Setup 1.
