AWS Controllers for Kubernetes vs env0

AWS Controllers for Kubernetes (ACK) lets Kubernetes users define AWS resources with Kubernetes custom resources. It periodically compares desired and actual AWS state and corrects drift. Documentation lists 74 service controllers, including S3, RDS, Lambda and DynamoDB. ACK supports declarative, version-controlled infrastructure alongside applications, across AWS accounts and regions. Read-only resources and read-only adoption support migration from other infrastructure-as-code tools. EKS users can install managed EKS Capabilities, where AWS handles controller installation and upgrades with automatic updates, auto-scaling and auto-tuning. Self-managed Helm installation runs on EKS, GKE, AKS, on-premises clusters and local environments, providing version and configuration control. AWS IAM authorizes controller access. Self-managed ACK costs nothing for Helm installation on Kubernetes 1.20+ on any Kubernetes cluster. EKS Capability pricing is hourly, with a base rate per enabled capability plus usage charges for each ACK resource managed.

env0 is a cloud control plane for governing infrastructure and helping teams manage, automate, and scale it. Developers and AI agents deploy through reusable templates and Git-based workflows, with RBAC, scoped variables, and policy-as-code guardrails. It supports Terraform, Terragrunt, Pulumi, OpenTofu, Kubernetes, Helm, Ansible, and AWS CloudFormation across cloud accounts, Kubernetes resources, and IaC-managed environments. Drift management detects changes across clouds, plans fixes with blast-radius context, remediates at the infrastructure-as-code source, and rescans. Cloud Asset Management maps resources across clouds, accounts, and SaaS providers to owners, costs, dependencies, and policy state. Listed integrations include GitHub, GitLab, Bitbucket, Azure DevOps, AWS, Azure, GCP, Slack, Microsoft Teams, Datadog, and Backstage. The Free Tier costs nothing, billed Free / Forever, with up to 30 active environments, 250 monthly deployments, one concurrent run, unlimited users and agents, and community support. Custom-priced Cloud Navigator and Cloud Pilot plans are also listed.
