Radar

Radar, made by Skyhook (operating under Y Combinator-backed KoalaOps, Inc.), is a Kubernetes UI that helps teams visualize and manage their clusters, providing topology views, event timelines, GitOps integration, Helm management, and cluster auditing across single or multiple clusters. It offers live service topology and traffic visualization, an event timeline with extended data retention beyond Kubernetes' default 1-hour TTL, and GitOps support for ArgoCD and Flux. Radar includes Helm release tracking with rollback capabilities, image filesystem inspection, 36 best-practice cluster audit checks, and AI diagnostics via the Model Context Protocol. It supports multi-cluster fleet management and search, with SSO and RBAC available in the Cloud version. The project shows active weekly-release development with more than 3,100 GitHub stars and strong community engagement. Pricing is freemium: Radar OSS is free forever under the Apache 2.0 license as a roughly 30MB binary, while Radar Cloud is a paid tier offering fleet aggregation, persistent retention, routed alerts, and SSO for teams managing multiple clusters.
