Tainer is an open-source, self-hosted dashboard for Proxmox VE. Teams deploy containers and VMs from a curated catalog, admins decide who can touch which cluster, and the whole thing runs from one Docker image on your own hardware.
docker pull tainersh/tainer
Every Proxmox site on one map, with live node and deployment counts.
Open source
Tainer was closed source until 2.0. Now the full codebase is on GitHub under the GNU Affero General Public License v3.0: the dashboard, the load balancer, Tainy and every security fix.
All you need is Node.js 24. Clone the repo, install and start the dev server. Security issues go through a private advisory, not a public issue.

One Tainer instance manages any number of Proxmox clusters. Teams get self-service, and admins keep control over who touches what.
Everything your team runs, in one list.
Know what changed before anyone asks.
Addresses handed out, not guessed.
Hand out access without handing out root.
An assistant that asks before it acts.
Install
Tainer ships as a single Docker image. No accounts, no licence keys, nothing that phones home.
AUTH_SECRET encrypts sessions and stored credentials. Put it in .env and keep it the same across upgrades.
echo AUTH_SECRET=$(openssl rand -base64 32) > .envSave the compose file next to .env and bring it up. Images are built for linux/amd64 and linux/arm64.
docker compose up -dOpen Tainer in the browser, create the first admin account, then add your Proxmox cluster under Platform > Sites.

Different tools, different priorities. Tainer manages multiple Proxmox sites from one install and focuses on container lifecycle, templates, and IPAM. PegaProx leans into cross-cluster orchestration. Here is the side-by-side, gaps and all.

In the Wild
Independent writeups that helped more people find Tainer. If you cover us, we'd love to send you a copy - [email protected].
Tainer gives you a clean, modern dashboard on top of Proxmox that finally makes managing LXCs and VMs feel like managing containers in Portainer.
Overall worth trying if you've been on the fence. Rough edges but solid foundation. Clean, smooth interface, fast and responsive, and HA cluster support is great.
Our Story
On June 4th, the idea for Tainer was born out of pure necessity. At the company we worked for, we urgently needed a reliable platform to manage and back up our LXC containers.
Crucially, we needed a way to use Veeam to back them up. Because Veeam didn't offer native support for Proxmox LXC containers at the time, we decided to build the bridge ourselves.
That bridge became Tainer - designed to give operations teams the container workflow and data protection they actually need for Proxmox.
