In their own words
Flux CD
Flux CD is a free, open-source set of continuous and progressive delivery tools for Kubernetes. It uses GitOps to reconcile clusters with configuration from sources such as Git repositories, and manages Kubernetes resources along with infrastructure and workload dependencies. Integrations include GitHub, GitLab, Bitbucket, S3-compatible buckets, OCI, container registries, Helm, and Kustomize. With Flagger, it supports canary deployments, feature flags, and A/B rollouts; it can also scan container images and push automated updates back to Git. Flux can send alerts to external systems, including chat systems such as Slack. For multi-tenancy, it uses Kubernetes RBAC through impersonation and supports multiple repositories and clusters. Its CLI and controller images are signed, and controller deployments follow the Kubernetes restricted pod security standard. Flux does not provide its own UI, although third-party interfaces are available. Installation requires cluster-admin rights, and older end-of-life Kubernetes versions are unsupported; the listed minimum versions begin at v1.34.1 for v1.34.
