Radar vs Lens

Q: Does Radar have a desktop app like Lens?

Radar OSS is a single Go binary. brew install , run kubectl radar , your default browser opens against your current kubeconfig. No Electron, no per-OS installer to maintain.

Q: Is there anything Lens does that Radar doesn't?

Two worth calling out. Real-time collaborative cursors in Lens Teamwork (Figma-style multi-cursor presence). Radar Cloud has shared workspaces and deep-links but not live cursor presence. In-app AI chat (Lens Prism) : Radar takes a different approach - the cluster is exposed as an MCP endpoint your existing Claude / Cursor / Copilot queries directly, rather than an in-app panel.

Native Go binary vs Electron. Per-cluster vs per-user pricing. Apache 2.0 with the full feature set vs MIT repo with exec/logs/shell moved proprietary.

TL;DR

Native binary, not Electron. Lens is Chromium + Node bundled as a per-laptop desktop app. Radar OSS is a single compiled Go binary serving the UI from one process.
The OSS story is asymmetric. Radar is Apache 2.0 with a public no-relicense pledge. The lensapp/lens repo is MIT, but Mirantis moved exec, logs, and shell proprietary in v6.3, so OpenLens shipped without them.
Per-cluster vs per-user. Lens Pro is ~$22-35/user/mo for commercial use. Radar prices per cluster - teammates are free. On a 50-engineer team that's the difference between $13-21k/year and $0.
Pick Radar if you want a team-shared, multi-cluster, historically-aware view with the modern K8s ecosystem auto-detected (ArgoCD + Flux, Karpenter, KEDA, OpenCost, Trivy). Pick Lens if you're a solo engineer who wants a polished single-cluster desktop IDE and Lens Pro is in your budget.

The architectural split

Desktop kubeconfig vs in-cluster ServiceAccount.

Lens · Desktop model

Your laptop · Lens Electron app

↓ reads ~/.kube/config (local)

Kubeconfig (distributed how?)

↓ direct K8s API call

Your cluster(s) · one at a time

Each engineer maintains their own kubeconfig. State is per-session per-laptop. Sharing a view = screensharing.

Radar Cloud · Hosted model

Your cluster(s) · Radar in-cluster as ServiceAccount

↑ outbound WebSocket over TLS

Radar Cloud (SOC 2, US/EU regions)

↓ browser via your IdP

Your team · shared view via SSO

One workspace per cluster fleet. No kubeconfigs shared, no VPN, no inbound firewall rules. (Radar OSS local mode reads kubeconfig - same as Lens - for solo use.)

FAQ

Questions we get about Lens.

Is Lens still open source?

The lensapp/lens repository is MIT-licensed. The Lens Desktop product Mirantis ships isn't equivalent to that repo: in v6.3 (Jan 2023), Mirantis moved exec, logs, and shell into proprietary code, so OpenLens (the OSS build) shipped without them. Lens Personal is free for individual non-commercial use; commercial use requires Lens Pro (~$22-35/user/mo) or higher, since Lens 6.0 (mid-2022).

What about OpenLens / FreeLens?

OpenLens is the community-maintained binary build of the OSS repo. It works, but lost exec/logs/shell when Mirantis moved them proprietary in v6.3. FreeLens is another community fork. Both work if you want the OSS Lens without paying for Pro.

Does Radar have a desktop app like Lens?

Radar OSS is a single Go binary. brew install, run kubectl radar, your default browser opens against your current kubeconfig. No Electron, no per-OS installer to maintain.

How does Radar differ from Lens reading kubeconfigs?

Lens uses your local kubeconfig to call the K8s API directly from your laptop. Radar Cloud runs in-cluster as a ServiceAccount and opens an outbound tunnel to the hosted control plane. Practically: no kubeconfig distribution, no shared credentials, no inbound firewall rules. Radar OSS local mode also reads kubeconfig (same as Lens) for solo use.

Is Lens more mature?

Lens has been around longer (since 2016) and has 1M+ users per Mirantis. Radar covers more of the modern Kubernetes ecosystem in core (ArgoCD + Flux, Karpenter, KEDA, Trivy, MCP) without needing extensions to be installed.

Is there anything Lens does that Radar doesn't?

Two worth calling out. Real-time collaborative cursors in Lens Teamwork (Figma-style multi-cursor presence). Radar Cloud has shared workspaces and deep-links but not live cursor presence. In-app AI chat (Lens Prism): Radar takes a different approach - the cluster is exposed as an MCP endpoint your existing Claude / Cursor / Copilot queries directly, rather than an in-app panel.
