About Rainbond

Rainbond is an open-source application platform that sits on top of Kubernetes and hides most of its complexity. Teams use a graphical interface to build, deploy, assemble and manage applications, so developers and operators without Kubernetes expertise can still run workloads on clusters.

The project describes a unified way to deploy ordinary business applications, projects generated by AI, open-source AI tools and LLM services, with AI assisting in deployment and operation. It targets private, self-hosted deployments on your own servers or Kubernetes clusters, and its README states that the core capabilities are fully open source.

The code is written in Go and published under a license that GitHub lists as 'Other', so review its terms before adopting it. Documentation and a Chinese-language README are provided, and the platform suits teams that want an internal PaaS and application delivery layer over Kubernetes.
