KodeKloud Notes

Lens is a free, open-source desktop application that provides complete situational awareness for Kubernetes. Whether you are a developer or site reliability engineer (SRE), Lens simplifies cluster management, deployment, monitoring, and troubleshooting in one unified interface.

Note

Lens is compatible with any certified Kubernetes distribution—Minikube, EKS, K3s, K0s—and works seamlessly on-premises or in the cloud.

Why Lens?

Managing Kubernetes often means switching between multiple tools and command-line interfaces. Even after running various commands, gaining real-time insights into your containerized workloads remains challenging. Lens changes this by consolidating your entire Kubernetes workflow into a single, unified interface—accelerating onboarding, deployment, monitoring, and troubleshooting to boost productivity and reduce time-to-market.

Smart Terminal

Switch contexts seamlessly across clusters without manually updating your kubeconfig. Manage production, staging, and development environments from one terminal window.

Helm Integration

Search, review, and deploy Helm charts directly within Lens. View chart details, customize values, and install in just a few clicks—no CLI required.

Extensions

Extend Lens with community and partner plugins. Add vulnerability scanning, resource-relationship visualizations, GitOps workflows, and more.
