summary
Kratix is an open source platform framework that implements a promise CRD (YAML) to declare services and orchestrates multi-cluster delivery by writing manifests to git or S3 rather than holding credentials to every cluster. It schedules by cluster labels (region, GPU, operators) and supports sending multiple documents to different targets, interoperating with Argo/Flux and other GitOps agents. Status flows back via the same Git-based channel (GitOps for status). A versioning feature took ~5 weeks to design and sat unused for 12 months before adoption.
