Argo CD vs Capistrano

Argo CD is a declarative GitOps continuous delivery tool for Kubernetes. It uses Git repositories as the source of truth for desired application state and automates deployment to target environments. It compares running applications with that desired state, displays differences, and supports manual or automatic synchronization. The tool can deploy to multiple clusters and works with Kustomize, Helm, Jsonnet, plain YAML or JSON manifests, and configured custom configuration management tools. A web UI shows real-time application activity, while a CLI supports automation and CI integration. Access features include multi-tenancy, role-based controls, and single sign-on integrations such as OIDC, OAuth2, LDAP, SAML 2.0, GitHub, GitLab, Microsoft, and LinkedIn. It also provides access tokens, audit trails, and Prometheus metrics. Local accounts do not provide advanced features such as groups or login history; the documentation recommends SSO for those needs. Argo CD is free and open source with a self-managed installation. A common multi-tenant deployment serves multiple developer teams and is typically maintained by a platform team; the non-high-availability installation is not recommended for production.
