Kube Composer

Kube Composer is a free, open-source Kubernetes YAML generator with a visual editor. It helps developers and DevOps teams create and manage Kubernetes deployment configurations, services, and other resources without manually writing YAML, and provides real-time visualization of the architecture.

Kube Composer is a visual Kubernetes YAML generator, which aligns with the 'Drag-and-Drop UI Builder' feature. It generates YAML, which is a form of code, allowing for 'Code Customization' in the sense that the output can be further modified. The tool can be run locally via Docker, suggesting 'Flexible Deployments'. It also explicitly states 'Mobile Responsive' support. However, it lacks direct API/database integrations for building internal tools, and its security features are not comparable to enterprise-grade access control systems like SSO/RBAC, which are core to the Retool concept. It's more of a configuration tool than a full low-code application development platform.
