All Virtual Machines, one web console.
Open vCenter is an open source virtualization center built to manage hundreds of thousands of VMs. Browse clusters, hosts and VMs, run power and lifecycle actions, edit hardware, manage templates and ISOs, and open a console - all from the browser.
Tested on Windows Server 2019 / 2022 / 2025 and Windows 11
Features

Architecture
See the whole stack
A web frontend, a backend API and worker, and a lightweight agent on every host - with RabbitMQ as the only path between the backend and your hypervisors. Switch between the Docker Compose and Kubernetes installs, click any component to see its real configuration, or follow a VM start from click to completion.
Quick install
Up and running in three commands
Published images, a Keycloak realm imported on first boot, test users for every role. Then add your Hyper-V hosts - each one runs the ovc-agent service.
Docker Compose
Everything on one machine behind nginx. Open http://localhost and log in as admin / admin.
git clone https://github.com/openvcenter/Open-vCenter.git
cd Open-vCenter/quick-install/docker
./up.shKubernetes
Plain manifests in the ovc-infra namespace, Traefik Ingress, PVCs for data.
git clone https://github.com/openvcenter/Open-vCenter.git
cd Open-vCenter/quick-install/kubernetes
./apply.shOpen source
Three components, three repositories
React 19 · TanStack Start · Tailwind
The web console. The only REST client - it proxies the API and serves the console tunnel.
Python · FastAPI · SQLAlchemy · aio-pika
REST API plus a RabbitMQ worker. Owns PostgreSQL and Valkey, enforces RBAC.
Go · Windows service · PowerShell
Runs on every Hyper-V host. Talks to the backend exclusively over RabbitMQ.
Click around before you install
The live demo is the real console with a simulated backend in your browser - no login, nothing to install.
