OpenCost
OpenCost is an open-source project built for monitoring and allocating cloud infrastructure and costs in real-time. It is designed to help organizations monitor and manage the cost of running their applications in Kubernetes and to identify opportunities for cost savings. OpenCost can provide a detailed cost breakdown for the individual applications, components, and also the cost associated with every container, pod, and deployment. The feature of providing real-time cost visibility allows organizations to monitor and visualize the cost of large Kubernetes environments where understanding resource utilization becomes a challenge. The detailed breakdown of cost OpenCost helps users to identify opportunities for cost savings and to make informed decisions.
Some features of OpenCost are:
- Real-time cost visibility for Kubernetes cluster, node, namespace, controller kind, service, and pod.
- Supports multi-cloud cost monitoring.
- Dynamic on-demand k8s asset pricing enabled by integrations with AWS, Azure, and GCP billing APIs.
- Supports on-prem Kubernetes clusters with custom CSV pricing.
Crossplane
Crossplane is an open-source Kubernetes extension that transforms your Kubernetes cluster into a universal control plane. It extends Kubernetes' native capabilities, i.e. orchestration and decentralization, to manage the cloud infrastructure resources. At its core Crossplane empowers platform and DevOps teams to assemble infrastructure from multiple cloud providers and expose self-service APIs for other teams to consume, without worrying about writing any code.
Crossplane transforms complex infrastructure configurations into reusable components that application developers can easily consume and manage cloud resources with the same tools and workflows they already use for Kubernetes custom resources.
With Crossplane, you can:
- Manage your cloud infrastructure directly from the Kubernetes cluster.
- Treat your infrastructure just like any other Kubernetes resource, using familiar tools and workflows.
- Define reusable infrastructure compositions that bundle multiple cloud resources into single, easy-to-consume packages.
- Manage resources across different cloud providers through a single interface.
vClusters
vCluster aka Virtual Cluster is a tool that creates fully functional multiple Kubernetes clusters inside your physical Kubernetes cluster. Unlike physical Kubernetes clusters, vClusters are lightweight and share the underlying host cluster's resources while maintaining complete logical separation. The virtual cluster enables teams to run multiple, isolated Kubernetes control planes on a single host cluster, making it ideal for development environments, testing, and multi-tenant scenarios. vCluster reduces infrastructure costs and complexity by eliminating the need for separate physical clusters while providing users with full administrative capabilities and a native Kubernetes experience.
Some features of vCluster are:
- Isolation: vCluster provides complete logical isolation between virtual clusters while running within shared boundaries. Each vCluster operates with its control plane components, allowing teams full administrative access without affecting other virtual clusters or the host cluster.
- Resource Efficiency: vCluster significantly reduces infrastructure costs by eliminating the overhead of running separate physical clusters. It intelligently shares the host cluster's compute resources, storage, and networking infrastructure while maintaining only essential control plane components for each virtual cluster.
- Scalability: vClusters can be rapidly created and destroyed on demand, making them highly scalable for dynamic environments. Organizations can easily spin up new development environments, testing spaces, or temporary clusters without provisioning additional infrastructure.
- Lightweight: The vCluster architecture is intentionally minimalistic, running only essential Kubernetes components. Each virtual cluster maintains a small footprint by using a streamlined control plane and sharing the host cluster's worker nodes.
Silver Surfer
Silver Surfer is an open-source Kubernetes utility that simplifies the critical process of Kubernetes version upgrades. It acts as an intelligent API version validator and migration assistant, helping DevOps teams identify and resolve deprecated API versions across their Kubernetes manifests and resources. By automatically analyzing your Kubernetes objects and providing clear migration paths, Silver Surfer ensures smooth cluster upgrades while minimizing the risk of version incompatibility issues. This tool is particularly valuable for organizations managing large-scale Kubernetes deployments where manual API version verification would be time-consuming and error-prone.
Neuvector
NeuVector is an open-source container security platform that provides full lifecycle container security, focusing on cloud-native applications and Kubernetes environments. It offers real-time vulnerability scanning, compliance monitoring, and network security through a zero-trust security model. The platform is particularly known for its container firewall capabilities and ability to protect containerized applications from development through production.
Key features of NeuVector include:
- CI/CD Vulnerability Management
- Violation Protection
- Threat Detection
- Run-time Vulnerability Scanning

Zarf
Zarf is an open-source tool designed for deploying and managing Kubernetes in air-gapped or limited-connection environments. Originally developed as part of a Naval Academy project for submarine deployments, Zarf simplifies the packaging and delivery of Kubernetes applications by allowing users to bundle all necessary resources, such as Helm charts and container images, into a single tarball. These packages can then be transported to an isolated environment for deployment.
Harbor
Harbor is an open-source artifact registry that helps you to securely store your container images. What makes Harbor special is its policies and role-based access control which ensures the images are scanned for vulnerabilities and image signatures are trusted. With Harbor, you can set policies for your images, scan them for vulnerabilities, and manage access through role-based controls. This makes it an essential tool for developers looking to ensure their container images are both secure and well-managed.
Key features of Harbor include:
- Self-Hosting: Users can deploy their own Harbor registry instance, allowing for complete control over their container images and security policies. Also by configuring a Self-hosted harbor registry users can execute secure deployments to air-gapped environments.
- Security Features: Implements access policies, vulnerability scanning, and image signing to ensure that only trusted images are used in production.
