# Radar > Documentation for Radar - the open-source Kubernetes visibility tool, and Radar Cloud, the hosted multi-cluster control plane. By Skyhook. ## Docs - [Alerts](https://radarhq.io/docs/cloud/alerts.md): Rule-driven, durable alerting on top of the live Issues stream - get notified when something breaks, and keep a history of what fired after it clears. - [Applications across clusters (fleet view)](https://radarhq.io/docs/cloud/applications.md): Fleet Applications groups workloads by the app they belong to and folds each app across the environments and clusters it runs in - one row per app, with version skew and promotion lag at a glance. - [Audit log](https://radarhq.io/docs/cloud/audit-log.md): Org-scoped activity log. Every mutation - cluster CRUD, member ops, billing, auth, PAT lifecycle - is recorded with actor, IP, and metadata. JSON or CSV export. - [Billing & plans](https://radarhq.io/docs/cloud/billing.md): Three plans - Free, Team, Enterprise. Per-cluster pricing on Team, customer Stripe portal, prorated subscriptions. - [Cluster token rotation](https://radarhq.io/docs/cloud/cluster-token.md): Cluster install tokens are bearer credentials. Rotate them when an operator leaves, when a value file leaks, or as part of routine hygiene. - [Connecting a cluster](https://radarhq.io/docs/cloud/connect-cluster.md): Install Radar in your Kubernetes cluster, what each Helm value does, RBAC scope, and how to verify the connection. - [Connected apps & MCP access](https://radarhq.io/docs/cloud/connected-apps.md): Connect external AI agents to your org over OAuth, manage their grants, and clamp the whole MCP surface to read-only with an org-wide access mode. - [Fleet views](https://radarhq.io/docs/cloud/fleet-views.md): Cross-cluster aggregates - issues, applications, search, audit checks, and package drift across every cluster connected to your org. - [Members & invitations](https://radarhq.io/docs/cloud/members.md): Invite members by email, set their role, and use domain auto-join so the right people land in your org without explicit invites. - [Notifications](https://radarhq.io/docs/cloud/notifications.md): Personal email preferences, the in-app inbox, and org-level Slack / generic webhook destinations for cluster, member, and billing events. - [Organizations & roles](https://radarhq.io/docs/cloud/organizations.md): Organizations are the tenant boundary in Cloud - they own clusters, members, billing, and audit. Three roles: owner, member, viewer. - [Radar Cloud overview](https://radarhq.io/docs/cloud/overview.md): How Radar Cloud is built - the hosted control plane, the in-cluster Radar pod, the tunnel, and what stays in your cluster vs. what goes to the cloud. - [Personal access tokens](https://radarhq.io/docs/cloud/personal-access-tokens.md): Mint per-user PATs for AI clients (Claude, Cursor, Claude Code) and CI scripts. Org-pinned at mint time, SHA-256 hashed at rest, revocable any time. - [RBAC under Cloud mode](https://radarhq.io/docs/cloud/rbac.md): How a Cloud user's role becomes a Kubernetes identity. The cloud:owner / cloud:member / cloud:viewer groups, the X-Forwarded-* headers, and how to override the default ClusterRoleBindings. - [Architecture](https://radarhq.io/docs/cloud/self-hosted/architecture.md): Component diagram, data flow, trust boundaries. - [Authentication](https://radarhq.io/docs/cloud/self-hosted/auth.md): OIDC + the always-available break-glass admin. WorkOS is not used in self-hosted - your IdP is the source of truth. - [Backups](https://radarhq.io/docs/cloud/self-hosted/backups.md): What's recoverable from K8s state alone, and what needs Postgres backups. - [Configuration reference](https://radarhq.io/docs/cloud/self-hosted/configuration.md): Every value the chart exposes and the env var it maps to in the running control plane. - [Self-hosted Radar Cloud](https://radarhq.io/docs/cloud/self-hosted/index.md): Run the Radar Cloud control plane inside your own VPC. The same Go API + web app we operate at app.radarhq.io, deployed via Helm in a customer-controlled cluster. - [Install](https://radarhq.io/docs/cloud/self-hosted/install.md): Helm walkthrough for self-hosted Radar Cloud. ~10 minutes from chart-add to first sign-in. - [Licensing](https://radarhq.io/docs/cloud/self-hosted/licensing.md): What gets sent home, the warn-only banner ladder, key rotation. - [Requirements](https://radarhq.io/docs/cloud/self-hosted/requirements.md): What you need before installing self-hosted Radar Cloud. - [Troubleshooting](https://radarhq.io/docs/cloud/self-hosted/troubleshooting.md): What to check when things go wrong. Failure modes from real installs, with the fix at the top. - [Upgrade](https://radarhq.io/docs/cloud/self-hosted/upgrade.md): Helm upgrade flow, migration safety, version-skew policy. - [SSO (SAML / OIDC)](https://radarhq.io/docs/cloud/sso.md): Self-serve SAML and OIDC setup via the WorkOS Admin Portal. Owner-only. Once configured, users in your IdP authenticate without going through email magic-link. - [Authentication](https://radarhq.io/docs/configuration/authentication.md): Radar's two auth modes - proxy headers and OIDC. Writes run as the user via Kubernetes impersonation; reads are authorized by your namespace access. - [CLI flags](https://radarhq.io/docs/configuration/cli.md): Every flag accepted by the radar / kubectl-radar binary, including auth, MCP, timeline storage, and Radar Cloud integration flags. - [Configuration files](https://radarhq.io/docs/configuration/files.md): Where Radar stores defaults and preferences, kubeconfig precedence, and how to switch between clusters and contexts. - [In-cluster deployment](https://radarhq.io/docs/configuration/in-cluster.md): Run Radar as a pod in your cluster for shared team access. Helm chart, ingress, RBAC opt-ins, and graceful permission degradation. - [Access control (RBAC visibility)](https://radarhq.io/docs/features/access-control.md): Inspect what any ServiceAccount, User, or Group can actually do - without three kubectl describe calls. Pod and Workload detail pages surface blast radius so you can answer 'what happens if this is compromised?' in one click. - [Applications view - browse a cluster by app](https://radarhq.io/docs/features/applications.md): Group a cluster's workloads into the application they belong to - resolved from ownership, GitOps, Helm, and labels - with a workload rail, topology, and search. Open source and Cloud. - [Cluster audit](https://radarhq.io/docs/features/cluster-audit.md): Built-in best-practices scan covering security, reliability, and efficiency.

Auto-detected when OpenCost is installed in the cluster. - [Exec & port-forward](https://radarhq.io/docs/features/exec-and-portforward.md): Pod terminal, debug containers, port forwarding, and a local terminal pane - all gated by RBAC and disable-able per install. - [GitOps (Argo CD & Flux)](https://radarhq.io/docs/features/gitops.md): Dedicated workspace for Argo CD Applications and Flux Kustomizations / HelmReleases - fleet view, per-app diagnosis, and one-click controls. Goes beyond status display: explains why something is OutOfSync, what's blocking deletion, and which controller is unhealthy. - [Helm management](https://radarhq.io/docs/features/helm.md): View installed Helm releases, inspect values and rendered manifests, track available upgrades, choose a version, rollback, and uninstall - all without leaving Radar. - [Image filesystem](https://radarhq.io/docs/features/image-filesystem.md): Inspect a container image's filesystem without pulling it locally.
