Why Radar Cloud Doesn't Cache Your Cluster State
Most multi-cluster dashboards copy your cluster state into a backend cache. Radar Cloud doesn't. Here's why the reverse-proxy model is the right call.
SSO and RBAC Without Passing Around Kubeconfigs
A contractor needs read-only access to one staging cluster by Monday. Without SSO and scoped RBAC, that ticket bounces for a week. Here's how Radar Cloud collapses it.
Cluster Audit: The 31 Checks That Catch What You Forgot
Most clusters fail the same checks. Radar's built-in audit runs 31 of them inline against your live state. Inspired by Polaris and the NSA / CISA hardening guide.
MCP for Kubernetes: Live Cluster Context for AI Tools
Pointing an AI at raw kubectl works, badly. Radar's built-in MCP server gives Claude, Cursor, and friends a token-optimized, RBAC-aware view of your cluster.
Why We Priced Radar Per Cluster, Not Per Seat
Per-seat pricing punishes a visibility tool's whole point: more eyes. The five pricing models we compared, why per-cluster won, where it's a worse deal.
Radar OSS or Radar Cloud? An Honest Take on When to Use Each
The most common question in our GitHub issues: do I need Radar Cloud, or is OSS enough? Here's the honest answer, with the five questions that actually decide it.
The Fleet Visibility Gap: Why Teams With 5+ Clusters Hit a Wall
Every tool that worked at 2 clusters breaks at 8. kubectl, Lens, k9s, Headlamp are all single-cluster-at-a-time. Here's where the wall is and what it looks like.
Radar's In-Cluster Architecture: Outbound-Only, Scoped, Live by Default
How Radar's in-cluster install works: outbound-only TLS, read-only RBAC by default, ~32MB RSS. The five questions every platform team asks, answered.
What We're Building in 2026: Radar OSS and Radar Cloud
Two shipping dates, one product line. Radar OSS in January, Radar Cloud in February. Here's the scope, the split, and what won't make it into v1.
Bring your first cluster online in 60 seconds.
Install the Helm chart, paste a token, see your cluster. No credit card required.
