What Kratix is

Kratix is an open-source framework for building internal developer platforms and coordinating platform capabilities. Its Promises define self-service APIs, workflows and fleet management for platform resources. Teams can encode policy and governance in reusable Promises and Workflows, then manage resources across clusters as a unified fleet. The maker describes access through portals, APIs, command-line interfaces, GitOps workflows, MCPs, automation and AI agents. The free Kratix Open Source plan includes the core, a Promise-writing CLI, Go and Python SDKs, revisions and upgrades, a metrics and observability endpoint, Marketplace access and Community Slack support. Marketplace examples include Redis, Jenkins and Amazon S3. Installation guidance covers Azure Kubernetes Service, Amazon EKS, Google Kubernetes Engine, Red Hat OpenShift and other Kubernetes setups. Paid SKA and SKE offerings have prices listed as Contact Us and include enterprise features such as integrations and security measures. The quick-start SeaweedFS-backed state store is intended for learning, not production use.

Verdict

Kratix provides a free core for building internal developer platforms, with paid offerings adding integrations, support and security features. The documentation cautions that the learning-oriented quick-start state store is not durable enough for production.
