Body

TL;DR: I had a vision for a read-only 3D visualization tool that translates our homelabs and network topologies into a living, breathing digital city. I don't have the programming skills or the financial resources to build this myself, but I wanted to share the concept with the community. Maybe it inspires a developer looking for a visually stunning open-source project, or maybe something like this already exists?

The Vision

We all spend countless hours building, securing, and maintaining our homelabs. But when it comes to visualizing them, we usually rely on static diagrams, standard dashboards, or dry terminal tables.

I had a vision: What if we could look at our network and say, "Wow, so this is my digital city"?

Imagine an animated, interactive WebGL map where your router is the city foundation, your firewall is the guarded city gate, and your services are the buildings. I would love to see a tool that takes Docker APIs and routing tables and turns them into a beautiful, isometric (or 3D) city that you can actually look at and explore.
The Metaphor (How it works)

To give you a concrete idea, here is how a typical hybrid-routing infrastructure would translate into the city model:

• The Streets & House Numbers: The physical NAS (and its main IP address) acts as the street itself. Because Docker services are exposed via specific ports, those ports become the literal house numbers along that street (e.g., 192.168.0.x Street, House No. 8096).
• The Buildings (Services): Every Docker container is a building constructed at its respective house number.
  • Nextcloud (at House No. 8080) might be a sleek corporate office building.
  • Paperless-ngx (at House No. 8000) acts as the central city archive or library, neatly filing away all documents.
• Public Transit (Network Traffic): The internal Docker networks and communication flows between containers (e.g., a service talking to its database) are visualized as tram or bus lines moving through the city.
• The City Gates (Public Access): A reverse proxy (like Nginx Proxy Manager) sits at the city walls like a toll booth. If you use a WAF with geo-blocking, it acts as strict border control, only letting verified traffic enter the city limits to access public-facing buildings.
• The Underground Tunnel & Main Station (Tailscale): Private admin tools (like Scrutiny, it-tools, or Portainer) don't have doors to the public street. Instead, a VPN/Mesh network like Tailscale acts as a highly secure, private underground metro. The tunnel ends right at the "Main Station" (the subnet router), allowing authorized users with active TailnetLocks to take a VIP elevator straight into the secure administrative buildings.
• City Security: Security tools like CrowdSec can be visualized as police patrols or security checkpoints actively monitoring the streets.

You would essentially be the mayor of your own “city.” If a house ever needs to be repaired or renovated, or if it can receive upgrades (e.g., via Watchtower), the mayor’s “office” would communicate with you using tools like ntfy. ntfy—if self-hosted—would then also serve as a building in the city, functioning as a large mail and package center.

The Technical Philosophy

For anyone who actually wants to build this, I think the core architecture should follow a strict "set-and-forget" and zero-trust mentality:

• Strictly Read-Only: The engine only pulls data (via Docker socket/API, routing tables, or maybe eBPF for traffic mapping). It does not manage or alter configurations.
• Lightweight Backend: The heavy lifting (the 3D rendering) must happen entirely in the client's browser (using Three.js, React Three Fiber, or Godot Web), keeping the backend footprint on the host server minimal.
• Zero Trust Design: It needs to be designed with strict security in mind, ensuring that exposing the dashboard doesn't expose the underlying network structure to unauthorized viewers.

Throwing the Idea over the Wall

As mentioned, I am just a homelab enthusiast with a vision. I don't have the coding expertise or the funds to develop this.

But if there is any frontend/3D developer or open-source team out there looking for an incredibly cool, visually stunning portfolio project: Please feel free to steal this idea and run with it!

For the rest of the community:

• Does anything even remotely close to this already exist?
• What are your thoughts on the concept and the technical feasibility?

Let me know what you guys think.
