DevOps Playgrounds
Remote sandbox environments for learning and experimenting without worrying about setup and cleanup. Run anything on vanilla Linux VMs, get a fresh Docker host or Kubernetes cluster in seconds, publish ports, collaborate via sharing terminal sessions, SSH from the command line, and more.
Official Collection
Playgrounds crafted by iximiuz Labs for efficient hands-on learning and safe experimentation.
Kubernetes Cluster
A multi-node Kubernetes cluster provisioned with kubeadm, allowing you to choose your preferred container runtime and networking plugin. Perfect for CKA, CKAD, and CKS preparation.
Coding Agent Base
Get a disposable agentic coding environment in seconds. Claude Code, Gemini CLI, OpenAI Codex, Opencode, and Plandex pre-installed and ready to use.
FlexBox
Your perfect base playground. Create purpose-built sandbox environments by choosing up to five VMs with custom root filesystems and organizing them into any number of local networks.
Independent Authors
Playgrounds from outstanding independent authors proudly hosted by iximiuz Labs.
Nix on Ubuntu

OpenSearch
OpenSearch is an open-source, enterprise-grade search and observability suite that brings order to unstructured data at scale.
Kubernetes the Hard Way
A manually assembled Kubernetes cluster, inspired by Kelsey Hightower's "Kubernetes the Hard Way" tutorial.
kubeadm
A single-machine playground to experiment with kubeadm, a tool built to provide best-practice "fast paths" for creating Kubernetes clusters.
Community Collection
Playgrounds contributed by the community members sharing their knowledge and expertise.
Uncloud Cluster
A multi-node Uncloud cluster with a standalone control node. About Uncloud: https://github.com/psviderski/uncloud
ArgoCD + Gitea
Experiment with GitOps - deploy a demo app to a Kubernetes cluster with ArgoCD, with app manifests stored in a Git repo hosted in Gitea.
Docker on Btrfs
Hands-on Docker on Btrfs: experiment with native snapshots, compression, and checksums; inspect setup, grow the filesystem live, and back up/restore images and containers.
Kube-composer
Open-Source Kubernetes YAML Builder with Intuitive Web Interface and Dynamic Visualization for Developers and DevOps Engineers kube-composer.com
Tailscale Homelab Access

ELK Stack
This is a hands-on ELK (Elasticsearch, Logstash, Kibana) playground enhanced with Docker and Beats to simulate real-world log and observability scenarios. It includes an Elastic Cluster (es-node-01 and es-node-02) for storing and indexing data, a test-node-03 running Docker with Filebeat, Metricbeat, and Heartbeat for log and metric collection, and kibana-node-04 for visualizing everything via Kibana UI—perfect for learning and experimentation.
ArgoCD with K3s 🎯
Welcome to the ArgoCD Playground, a lightweight K3s cluster pre-configured with ArgoCD for GitOps-based continuous deployment, Helm for package management, and the ArgoCD CLI for managing applications via the terminal.
