Is Radar worth the price?
Good value
Run OSS if one team can live without hosted fleet SSO.
Cloud Free is enough for up to 3 clusters. Team at $149 per cluster is the first real bill and it scales with cluster count, not headcount.
Enterprise at $299 is the SSO / SCIM / long-retention seat.
Hidden Costs & Gotchas
$149 times cluster count.
Annual discount is 20%, not more.

Radar FAQ
How does Radar help DevOps teams manage Kubernetes clusters?
Radar is an open-source Kubernetes UI and MCP server that runs on your laptop or in-cluster, providing topology, Helm, GitOps, image filesystem, audit, and MCP features. Its OSS binary is free forever under Apache 2.0, making it a cost-effective tool for daily cluster operations.
Can Radar replace Lens for Kubernetes monitoring?
Radar is a direct open-source competitor to Lens, offering a Kubernetes UI plus a built-in MCP server that Lens does not include in its free tier. Unlike Lens's per-seat model, Radar's Cloud Free tier supports up to 3 clusters with unlimited users, while paid plans use per-cluster pricing.
Why does Radar's Cloud Free tier limit timeline retention to 24 hours?
The Cloud Free tier keeps only 24 hours of timeline data as a trade-off for offering a no-cost entry point with unlimited users across three clusters. For longer historical retention, teams can upgrade to Radar's paid Cloud plans.
Which teams benefit most from Radar's per-cluster pricing model?
Teams with many viewers but a moderate number of clusters benefit most because Radar never charges per seat. This makes it ideal for organizations that need to give unlimited team members access without scaling costs per user.
How is Radar priced?
Radar offers a free open-source binary and a Cloud Free tier supporting up to three clusters with unlimited users. Paid Cloud plans are per cluster per month with Team and Enterprise tiers; annual subscriptions carry a discount. There is no per-seat charge.
How does Radar's MCP server integrate with AI workflows?
Radar includes an MCP server in its open-source version, enabling AI-driven automation and interactions with Kubernetes clusters. This server is freely available in the OSS build, not locked behind a Cloud subscription, so teams can use it locally or in-cluster.
Can Radar manage GitOps workflows for Kubernetes deployments?
Yes, Radar provides GitOps features in its open-source version alongside Helm chart management and an image filesystem viewer. These tools allow teams to track, deploy, and reconcile Kubernetes resources directly from the UI.
When would a team use Radar's audit feature?
Teams use Radar's audit feature to log and review cluster operations for compliance, security, and troubleshooting. This feature is available in the free open-source version, requiring no paid plan for basic historical tracking.
