Headlamp

Overview

Headlamp is a graphical interface for managing Kubernetes clusters, with web and desktop versions for people who prefer visual controls. It is best suited to operators working across clusters who want a free, open-source tool; teams should weigh its browser token handling and plugin security model.

Key features

Headlamp tailors the actions users see to their Kubernetes RBAC permissions. This makes the interface more pertinent to each role, while leaving access control with Kubernetes rather than replacing it. Users can monitor multiple clusters and switch between them in one interface, a practical advantage for operators responsible for several environments.

It supports client-certificate and bearer-token logins, and its installation guide also documents OIDC. Headlamp may store a user token in browser local storage, though it does not store the token in its backend or server. That distinction matters to teams assessing where credentials persist and how users access the web application.

Plugins extend the application for specific workflows, with integrations including Backstage, Flux, Inspektor Gadget, Kompose, Kubescape, KubeVirt, OpenCost, Prometheus and Trivy. The flexibility carries a security trade-off: plugins run in the same JavaScript context as the main application, so the project advises installing only trusted plugins.

Teams can deploy Headlamp in Kubernetes with Helm or a YAML configuration. The desktop app is tested on Windows, macOS and Linux. The project aims for monthly feature releases, with bug-fix versions between them as needed. For support, users can turn to documentation, community Slack, GitHub issues and a monthly community meeting.

Pricing

Headlamp is free, with no trial required: its Headlamp plan costs nothing and is open source under Apache 2.0. There is no lower paid tier to trade features against or published seat or quota cap to factor into a purchase. That makes it an uncomplicated fit for individuals and teams seeking a no-charge Kubernetes interface, though organizations should still evaluate its operational and security fit.

Platforms

Headlamp is available as a browser-based web application and as a desktop application for Windows, macOS and Linux. It can also be deployed in a Kubernetes cluster, making it relevant to self-hosted environments. Its listed platforms include extension, Linux, macOS, self-hosted, web and Windows.

Who it's for

Headlamp suits Kubernetes users who want a graphical way to move among clusters while seeing controls appropriate to their RBAC role. Its free Apache 2.0 plan is particularly compelling for teams that can manage their own deployment and choose plugins carefully. It is a weaker fit for organizations that are not comfortable with browser-side token storage or third-party plugins sharing the application's JavaScript context.

Pros and cons

• Pros: Free and open source under Apache 2.0, with web and desktop access and no trial gate.
• Pros: Multi-cluster monitoring and switching are built into the interface, useful for operators covering multiple clusters.
• Pros: RBAC-aware controls align the visible actions with each user's Kubernetes permissions.
• Pros: Helm and YAML deployment options, plus a plugin system and integrations, support varied workflows.
• Cons: Browser local storage may hold a user token, a consideration for teams with strict credential-handling requirements.
• Cons: Plugins share the main application's JavaScript context, so untrusted additions create a meaningful security concern.

Alternatives

Container Management Software is a useful starting point for comparing tools across the broader category.

• Docker Desktop is worth considering for users who want Docker Engine and Kubernetes alongside Docker Hub, Scout and Debug; its Personal plan is free, while Pro costs $9 a month.
• Kubermatic Kubernetes Platform offers an open-source Community Edition and an Enterprise Edition with consumption-based subscription pricing, making it an option for those comparing community and enterprise editions.
• MicroK8s may suit users looking for a free Kubernetes distribution, with no license fees for MicroK8s and Ubuntu Pro Personal covering up to 5 machines.
• Lens K8S IDE is another option for users who want multi-cluster management, metrics, real-time logs, resource visualization, a Smart Terminal and Helm management in its free Personal plan.
• vCluster Platform is a better fit when virtual-cluster capacity is the priority: its free plan allows unlimited virtual clusters up to 64 CPUs or 32 GPUs, with a maximum of one HA vCluster.
• Kubernetes is the free, open-source platform itself for readers seeking Kubernetes rather than a separate graphical management interface.
• Portainer offers a Business Edition free tier for up to 3 nodes, with full features and no time limit, which may suit smaller deployments seeking a node-capped free option.
• Podman is a free, open-source alternative for container, pod and image management, including Podman Desktop.

Verdict

Choose Headlamp if you want a free, open-source graphical interface for Kubernetes that brings multi-cluster navigation and role-aware controls together. Its central advantages are breadth of access and extensibility without a license fee; look elsewhere if browser token persistence or the shared plugin context is incompatible with your security requirements.
