24 alternatives to VCluster Free – Free K8s Multi-Tenancy with Virtual Clusters
vcluster is an open source tool for Kubernetes multi tenancy and over the years it has matured to have hosted controlplane virtual cluster, shared virtual clusters but the host cluster problem was always there. With vcluster standalone, you can now create the first cluster also with the same developer experience and consolidate the multiple vendor problem. With this, you can now use vcluster for entire multi tenancy spectrum. Feel free to discuss, happy to answer any questuons.
VCluster Free provides virtual Kubernetes clusters for multi-tenancy environments at no cost. It enables users to create and manage isolated Kubernetes clusters within a single physical cluster, useful for teams… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hi HN — I’m AJ, Co-founder of Snapser. We built a modular backend for apps/games with an “own cluster” feel (strong isolation), implemented on Kubernetes namespaces under the hood. Today we’re launching our free Starter Tier. Highlights: • 33 “Snaps” (Auth, Storage, Leaderboards, Analytics, A/B Tests, etc.) • Bring your own containerized services (any language) • Your own isolated environment (namespaces + bin-packing + auto-scaling) • Starter Tier: 1 dev cluster, 2 admin seats, 5 Snaps free, no credit card What we learned: isolation over giant shared control planes; smart…

I wanted to see how fast an isolated code sandbox could start if I never had to boot a fresh VM. So instead of launching a new microVM per execution, I boot Firecracker once with Python and numpy already loaded, then snapshot the full VM state. Every execution after that creates a new KVM VM backed by a `MAP_PRIVATE` mapping of the snapshot memory, so Linux gives me copy-on-write pages automatically. That means each sandbox starts from an already-running Python process inside a real VM, runs the code, and exits. These are real KVM VMs, not containers: separate guest kernel, separate guest…

Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack…

hey guys. the other day i was migrating hosting providers and i just needed something not too heavy and convenient to spin up my backups for awhile and realised there is almost nothing out there. kimchi hasn't been updated for years and cockpit is heavy. so here's something i came up with in a couple hours because of a sudden urge, nothing fancy just basic creation with cloud init, lifecycle management and image/storage, but it's modern-ish and it compiles to a 8.4mb binary inclusive of the embedded web UI, CLI and API, and only dep is libvirt.

Hello HN community! I'm excited to share K8s Cleaner, a tool designed to help you clean up your Kubernetes clusters. As Kubernetes environments grow, they often accumulate unused resources, leading to confusion, waste, and clutter. K8s-cleaner simplifies the process of identifying and removing unnecessary components. The tool scans your Kubernetes clusters for unused or orphaned resources—including pods, services, ingresses, and secrets—and removes them safely. You can fully customize which resources to scan and delete, maintaining complete control over what stays and what goes. Getting…

This is the newest update to my CLI tool to quickly create cheap Kubernetes clusters in Hetzner Cloud. This update adds autoscaling support, so clusters created with this tool now can behave similar to managed Kubernetes clusters, which I think is awesome. I received a lot of feedback since the last update so I hope anyone interested could try the new version as well. Thanks a lot for the feedback so far! The repo: https://github.com/vitobotta/hetzner-k3s

Since there’s a few discussions recently on $4 VPSes we thought you might be interested in Symbiosis, a cheaper and simpler managed k8s provider. Supported features include external LBs, encrypted+replicated storage and autoscaler. Infrastructure can be managed with UI, CLI, Terraform or Pulumi. Control planes are free of charge and a 1vCPU/2GB node goes for $6 per month. We’re live in Germany right now and we’re expanding into US during 2023. Feel free to try it out and leave a comment.
