In their own words
Kusion
Kusion is a free, open-source platform orchestrator for internal developer platforms. Its AppConfiguration lets developers describe application workloads and resource dependencies without setting environment-specific values. The declarative model combines workload, accessory, pipeline, and dependency concepts. The documented process moves through Write, Generate, and Apply, with a three-way diff preview before changes are applied. Kusion currently applies operations to Kubernetes, Terraform, and on-premises infrastructure. Platform engineers can create reusable modules to standardize deployments and support developer self-service. A built-in delivery pipeline can be extended with customized plugin steps managed by platform owners. The project describes security and compliance support through base models, policy-as-code guardrails, and automatic injection of accessory secrets into workloads. External secret-store guides cover AWS, Alibaba Cloud, and Viettel Cloud. Kusion is a lightweight client-side solution with APIs for integration and automation. Its CLI installation methods cover macOS, Linux, and Windows. The project calls itself early and rapidly iterated; help and feedback are available through Slack or GitHub issues.
Terramate
Terramate is an Infrastructure as Code orchestration and observability platform for platform teams. It helps teams package reusable infrastructure patterns so developers and AI agents can self-serve across environments. Terramate Cloud lists Terraform, OpenTofu, and Terragrunt as supported tools. Its capabilities include stacks, orchestration, custom workflows, rendered pull request plan previews, GitOps, drift detection, and drift reconciliation. Integrations include GitHub Actions, GitLab CI/CD, Bitbucket Pipelines, and Azure DevOps, and pull request integration is documented for GitHub, GitLab, Bitbucket, and other VCS platforms. Terramate says it does not need access to customer cloud accounts, state files, or source code; the CLI removes sensitive values from plan data before syncing it to the cloud. It lists AES-256 encryption at rest and HTTPS with TLS 1.2 for communications. Supported clouds are AWS, Google Cloud, and Azure. State management is self-hosted. Community is free for up to 2 users and 1,000 resources; Teams costs $449 a month and supports unlimited users and up to 5,000 resources. Enterprise pricing is custom.
