Kusion
What it is
Kusion is a free, open-source platform orchestrator for internal developer platforms. Its AppConfiguration model lets developers describe an application workload and its resource dependencies without adding environment-specific values. The specification combines workloads, accessories, pipelines, and dependencies in an infrastructure-independent declarative format. The documented workflow proceeds 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 infrastructures. Platform engineers can create reusable modules to standardize deployments and support developer self-service. A built-in delivery pipeline can be extended with plugin-based steps managed by platform owners. The project describes security and compliance support through base models, third-party policy-as-code guardrails, and automatic injection of accessory secrets into workloads. Its secret-store guides cover AWS, Alibaba Cloud, and Viettel Cloud. Kusion is a client-side solution with APIs for integration and automation, and its CLI has installation methods for macOS, Linux, and Windows. The project calls itself early and rapidly iterated; support is available through Slack or GitHub issues.
For and against
For
- Free and open source
- Three-way diff preview before applying changes
- Reusable modules support deployment standards
