In their own words
Google Config Sync
Google Config Sync keeps configuration and policies aligned across Kubernetes clusters by monitoring a source of truth and reconciling cluster state. It can sync files from Git repositories, OCI images and Helm charts, and apply Policy Controller constraints to registered and connected clusters. Namespace management supports multi-tenancy through namespace-scoped policies such as RBAC roles. Config Sync supports Autopilot and Standard GKE clusters, plus GKE-attached clusters including EKS and AKS. Clusters must be registered to a fleet before the service can be enabled. Its architecture combines hosted Google Cloud components with open-source components running on GKE. For OCI repositories, it can integrate with an admission webhook signature verification server to help ensure only trusted images are used. Config Sync is included with Google Kubernetes Engine at free, subject to a GKE-supported cluster version and fleet registration. It runs only on x86-based nodes, not Arm nodes. The drift-prevention admission webhook can use high memory and cause out-of-memory errors in clusters with many custom resources.
Plural
Plural is an AI tool for infrastructure work, presented for platform and DevOps teams. It can upgrade clusters, resolve incidents, patch vulnerabilities, optimize costs, and execute changes across code, clusters, and cloud. Its project-scoped Workbenches package an AI agent’s prompt, capabilities, tools, and automation triggers for infrastructure operations. Plural says agents can draw on a live semantic graph covering clusters, stacks, services, and changes across an estate. Integrations include Prometheus, Datadog, Loki, Elastic, Tempo, Jaeger, GitHub, GitLab, Bitbucket, Slack, Microsoft Teams, Jira, and Linear. Cloud tools provide SQL-queryable access to AWS, GCP, and Azure data, including billing and infrastructure services. Changes are submitted as pull requests in existing repositories for human review. Plural says actions are logged, permissions are bounded, tool calls and decisions can be inspected, and changes can be reviewed before confirmation. Sandbox is free for a 14-day platform trial. Pro starts at $450/mo for one cluster, with each additional cluster at $250/mo, and includes a 30-day free trial. Pro uses shared Plural infrastructure; Enterprise offers shared, dedicated, or on-prem hosting.
