Headlamp in 2025: Project Highlights

This year, we were excited to work with several students through the Linux Foundation’s Mentorship program, and our mentees have already left a visible mark on Headlamp:

Managing multiple clusters is challenging: teams often switch between tools and lose context when trying to see what runs where. Headlamp solves this by giving you a single view to compare clusters side-by-side. This makes it easier to understand workloads across environments and reduces the time spent hunting for resources.

Kubernetes apps often span multiple namespaces and resource types, which makes troubleshooting feel like piecing together a puzzle. We’ve added Projects to give you an application-centric view that groups related resources across multiple namespaces – and even clusters. This allows you to reduce sprawl, troubleshoot faster, and collaborate without digging through YAML or cluster-wide lists.

Changes:

• New “Projects” feature for grouping namespaces into app- or team-centric projects
• Extensible Projects details view that plugins can customize with their own tabs and actions

Day-to-day ops in Kubernetes often means juggling logs, terminals, YAML, and dashboards across clusters. We redesigned Headlamp’s navigation to treat these as first-class “activities” you can keep open and come back to, instead of one-off views you lose as soon as you click away.

Changes:

• A new task bar/activities model lets you pin logs, exec sessions, and details as ongoing activities
• An activity overview with a “Close all” action and cluster information
• Multi-select and global filters in tables

When something breaks in production, the first two questions are usually “where is it?” and “what is it connected to?” We’ve upgraded both search and the map view so you can get from a high-level symptom to the right set of objects much faster.

Changes:

• An Advanced search view that supports rich, expression-based queries over Kubernetes objects
• Improved global search that understands labels and multiple search items, and can even update your current namespace based on what you find
• EndpointSlice support in the Network section
• A richer map view that now includes Custom Resources and Gateway API objects

We’ve put real work into making OIDC setup clearer and more resilient, especially for in-cluster deployments.

Changes:

We’ve broadened how you deploy and source apps via Headlamp, specifically supporting vanilla Helm repos.

Changes:

• A more capable Helm chart with optional backend TLS termination, PodDisruptionBudgets, custom pod labels, and more
• Improved formatting and added missing access token arg in the Helm chart
• New in-cluster Helm support with an --enable-helm flag and a service proxy

Finally, we’ve spent a lot of time on the things you notice every day but don’t always make headlines: startup time, list views, log viewers, accessibility, and small network UX details. A continuous accessibility self-audit has also helped us identify key issues and make Headlamp easier for everyone to use.

Changes:

• Significant desktop improvements, with up to 60% faster app loads and much quicker dev-mode reloads for contributors
• Numerous table and log viewer refinements: persistent sort order, consistent row actions, copy-name buttons, better tooltips, and more forgiving log inputs
• Accessibility and localization improvements, including fixes for zoom-related layout issues, better color contrast, improved screen reader support, and expanded language coverage
• More control over resources, with live pod CPU/memory metrics, richer pod details, and inline editing for secrets and CRD fields
• A refreshed documentation and plugin onboarding experience, including a “Learn” section and plugin showcase
• A more complete NetworkPolicy UI and network-related polish
• Nightly builds available for early testing

Alongside the new AI Assistant, we’ve been growing Headlamp’s plugin ecosystem so you can bring more of your workflows into a single UI, with integrations like Minikube, Karpenter, and more.

Highlights from the latest plugin releases:

Alongside new additions, we’ve also spent time refining plugins that many of you already use, focusing on smoother workflows and better integration with the core UI.

Changes:

We’ve focused on making it faster and clearer to build, test, and ship Headlamp plugins, backed by improved documentation and lighter tooling.

Changes:

We’ve also been investing in keeping Headlamp secure – both by tightening how authentication works and by staying on top of upstream vulnerabilities and tooling.

Updates:

• We’ve been keeping up with security updates, regularly updating dependencies and addressing upstream security issues.
• We tightened the Helm chart’s default security context and fixed a regression that broke the plugin manager.
• We’ve improved OIDC security with PKCE support, helping unblock more secure and standards-compliant OIDC setups when deploying Headlamp in-cluster.
