Overview

Radar is a local-first Kubernetes management UI that provides topology visualization, resource browsing, and service traffic monitoring. It operates as a single binary without requiring cluster-side installation. The project includes a built-in MCP server implementation that enables AI assistants to query Kubernetes resources through Radar, with specific MCP tools for GitOps management and cluster operations. The project is actively maintained with regular updates and a growing user base.
