Kargo vs Weave GitOps

Kargo is an open-source continuous promotion orchestration layer for moving applications through deployment stages in Kubernetes environments. It complements Argo CD, with customizable pipelines for advancing changes from one environment to another and a view of changes across environments. Kargo tracks updates from Git artifacts, container images, Helm charts, and other artifacts. Verification checks can run at stages before an artifact advances downstream. Documented promotion steps include Git operations, Helm, Kustomize, Argo CD, and HTTP requests to external services. Kargo Enterprise additionally lists Jira, ServiceNow, JFrog Evidence, GitHub Actions, and Slack or email notifications, and can automatically return a stage to its last stable artifact when verification fails. The open-source distribution uses the Apache 2.0 license. A basic installation requires a Kubernetes cluster, and the documentation says Kargo works best paired with Argo CD. Its default configuration is suitable only for trying it in a local cluster that is not internet-facing. The open-source distribution has no time- or severity-bound backport guarantee for security fixes. Akuity Pro, including one Kargo instance, is listed at $495 a month; Enterprise pricing is available by contacting sales.

Weave GitOps extends Flux with deployment insights and tools for continuous delivery across teams. Its dashboard lets operators inspect application lifecycles, detect drift, check cluster health, roll back changes, and monitor operations. Both Open Source and Enterprise require a running Kubernetes cluster. The free Open Source edition includes a GitOps CLI for macOS and Linux. Enterprise adds deployment across multiple clusters in cloud and hybrid environments using Git and Cluster API. It supports canary, blue/green, and A/B rollouts, with success and rollback criteria based on metrics from Prometheus, Datadog, or New Relic. Enterprise also offers policy-as-code checks at commit, build, deploy, and runtime stages, plus team workspaces, multi-tenancy, role-based access, and enterprise identity integration. OIDC login and Kubernetes RBAC govern access. Infrastructure integrations include Terraform, Crossplane, and any Cluster API provider. Enterprise advertises critical 24/7 support for workloads and requires an entitlement from Weaveworks. The Open Source installation guide notes that dashboard login sessions are not persisted when scaling to multiple replicas.
