Homelable — Installation

Quick Start — Docker

curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/install.sh | bash
cd homelable && docker compose up -d

Open http://localhost:3000 — login with admin / admin.

Change the password before exposing to a network: edit .env and update AUTH_USERNAME / AUTH_PASSWORD_HASH.

Generate a new hash:

docker compose exec backend python -c 'import bcrypt; print(bcrypt.hashpw(b"yourpassword", bcrypt.gensalt()).decode())'

⚠️ bcrypt hashes contain $ characters — how to handle them depends on where you set the value:

• .env file (recommended): wrap the hash in single quotes → AUTH_PASSWORD_HASH='$2b$12$...'
• docker-compose.yml environment: block: escape every $ as $$ — use this command to generate a pre-escaped hash:

  docker compose exec backend python -c 'import bcrypt; print(bcrypt.hashpw(b"yourpassword", bcrypt.gensalt()).decode().replace("$", "$$"))'
  

Quick Start — Frontend only

curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/install.sh | bash -s -- --standalone
cd homelable && docker compose up -d

Update (Docker)

Re-run the install script — it detects an existing install and only updates docker-compose.yml:

curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/install.sh | bash
cd homelable && docker compose pull && docker compose up -d

Pre-built Docker images

The quick starts above never build anything — install.sh writes docker-compose.prebuilt.yml (or docker-compose.standalone.yml with --standalone) as your docker-compose.yml, and both pull ready-made images. They are published to the GitHub Container Registry on every push to main and every v* tag, for linux/amd64 and linux/arm64:

Image	Contents
ghcr.io/pouzor/homelable-backend	FastAPI API, scanner, status checker
ghcr.io/pouzor/homelable-frontend	React SPA behind nginx, proxying /api to the backend
ghcr.io/pouzor/homelable-frontend-standalone	Same SPA built with VITE_STANDALONE=true — no backend, canvases in localStorage
ghcr.io/pouzor/homelable-mcp	MCP server exposing the canvas to AI clients

Tags: latest (tip of main), plus X.Y.Z and X.Y for releases.

To wire it up by hand instead of using install.sh:

curl -fsSLO https://raw.githubusercontent.com/Pouzor/homelable/main/docker-compose.prebuilt.yml
curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/.env.example -o .env
docker compose -f docker-compose.prebuilt.yml up -d

Update the same way: docker compose -f docker-compose.prebuilt.yml pull && … up -d.

Scanning from Docker — MAC addresses

Out of the box the backend runs on a Docker bridge network, and the scan will never report a MAC address from it. MACs come from ARP, which is layer 2: the container's ARP cache holds only the Docker gateway, and nmap can read a target's hardware address only when that target sits in the same broadcast domain. From a bridge every LAN host is one hop away behind the gateway, so the field stays empty. cap_add: NET_RAW does not change this — the capability grants raw sockets, not a place on the LAN.

This also affects device identity. When a device is rescanned it is matched on MAC first and IP second, so without MACs a DHCP lease change makes the device come back as a new entry in the inventory instead of updating the old one.

To collect MACs, put the backend on the LAN itself. In docker-compose.yml (or docker-compose.prebuilt.yml), comment out the backend's networks: key and uncomment:

    network_mode: host

then docker compose up -d. Caveats:

• Linux only. On Docker Desktop for macOS and Windows the containers run inside a VM, so host networking still does not reach your physical LAN. There is no MAC-capable Docker setup on those platforms — run the bare-metal install instead.
• The backend binds 8000 directly on the host, with no port mapping and no network isolation from other host services.
• frontend and mcp reach the backend at http://backend:8000 over the homelable bridge; once the backend leaves that network they need http://127.0.0.1:8000 instead. Set BACKEND_URL on mcp, and for the front end either give it network_mode: host too or point its nginx proxy at the host address.

The alternative, if you would rather keep the backend isolated, is a macvlan network, which gives the container its own MAC and IP on your physical LAN. It needs a parent interface and a spare address range from your subnet, and on most setups the Docker host itself cannot talk to a macvlan container without an extra shim interface.

Build from source

docker-compose.yml at the repo root builds the images locally instead of pulling them — use it for development, or to run a patched tree.

git clone https://github.com/Pouzor/homelable.git
cd homelable
cp .env.example .env
docker compose up -d

Proxmox LXC Install

You can now install Homelable with community-scripts (proxmox-VE) :

https://community-scripts.org/scripts/homelable

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/homelable.sh)"

---

Bare metal — no Docker

scripts/install-baremetal.sh installs Homelable natively on a Debian 12+ / Ubuntu 22.04+ host (physical, VM or LXC): a Python venv and a homelable systemd unit for the backend on 127.0.0.1:8000, the built frontend served by nginx on port 3000.

git clone https://github.com/Pouzor/homelable.git /opt/homelable
sudo bash /opt/homelable/scripts/install-baremetal.sh

It prompts for the admin password and the CIDR range to scan, then writes backend/.env with a generated SECRET_KEY and bcrypt hash. Open http://<host-ip>:3000.

The script can also clone for you — run it from anywhere and it fetches the repo into INSTALL_DIR when that directory is empty. Piped into bash there is no terminal to prompt on, so pass the two answers as environment variables:

curl -fsSL https://raw.githubusercontent.com/Pouzor/homelable/main/scripts/install-baremetal.sh \
  | sudo ADMIN_PASSWORD=hunter2 SCANNER_RANGES='["192.168.1.0/24"]' bash

Without them the prompts are skipped and their defaults apply — the password becomes admin and the range is guessed from the primary interface. The script warns when that happens; change the password before exposing the host.

Re-running is safe and is how you upgrade — an existing backend/.env is kept untouched, everything else is rebuilt:

cd /opt/homelable && git pull
sudo bash scripts/install-baremetal.sh

Options

Every setting is an environment variable. Setting them all skips every prompt, which is what makes an unattended install possible:

sudo HTTP_PORT=8080 ADMIN_PASSWORD=hunter2 SCANNER_RANGES='["10.0.0.0/24"]' \
  bash scripts/install-baremetal.sh

Variable	Default	What
INSTALL_DIR	/opt/homelable	Repo root
REPO_URL / REPO_REF	upstream / main	Used only when INSTALL_DIR is empty
SERVICE_USER	homelable	systemd User=
BACKEND_PORT	8000	uvicorn port, bound to loopback
HTTP_PORT	3000	nginx port
SERVER_NAME	_	nginx server_name
ADMIN_PASSWORD	prompt, else admin	Initial password for user admin
SCANNER_RANGES	prompt, else guessed	JSON array of CIDRs
SKIP_NGINX=1	off	Do not install or touch nginx

Afterwards

systemctl status homelable
journalctl -u homelable -f

• Config: /opt/homelable/backend/.env — every other option (OIDC, MCP, Proxmox, Zigbee, Z-Wave, live view) is documented in .env.example. systemctl restart homelable after an edit.
• Data: /opt/homelable/data — SQLite DB and uploads. Back up this folder.
• nginx site: /etc/nginx/sites-available/homelable.

Change the password later:

/opt/homelable/backend/.venv/bin/python -c \
  'import bcrypt; print(bcrypt.hashpw(b"newpassword", bcrypt.gensalt()).decode())'
# put it in backend/.env as AUTH_PASSWORD_HASH='$2b$12$...' (keep the single quotes)
systemctl restart homelable

⚠️ Keep JSON values in backend/.env single-quoted — CORS_ORIGINS='["http://…"]'. systemd's EnvironmentFile parser strips bare double quotes, which breaks the JSON before the backend parses it. This does not apply to the Docker install.

Scanning as a non-root service

The unit runs as homelable, not root, so nmap has no raw sockets and silently falls back to a TCP connect scan: hosts and open ports are still found, OS detection (-O) and SYN scan (-sS) are not. To grant them, uncomment in /etc/systemd/system/homelable.service:

AmbientCapabilities=CAP_NET_RAW CAP_NET_ADMIN
CapabilityBoundingSet=CAP_NET_RAW CAP_NET_ADMIN

then systemctl daemon-reload && systemctl restart homelable.

Your own reverse proxy

With SKIP_NGINX=1 the script leaves the front end to you: serve /opt/homelable/frontend/dist as a static SPA and proxy the API to the backend. The nginx translation of docker/nginx.conf — what the script writes, with backend:8000 replaced by 127.0.0.1:8000:

server {
    listen 3000;
    server_name _;
    root /opt/homelable/frontend/dist;
    index index.html;

    client_max_body_size 20M;

    # WebSocket — must come before /api/ to take priority
    location /api/v1/status/ws/ {
        proxy_pass http://127.0.0.1:8000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }

    location /api/ {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }

    # Legacy /ws/ path
    location /ws/ {
        proxy_pass http://127.0.0.1:8000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
    }

    location / {
        try_files $uri $uri/ /index.html;
    }
}

Terminating TLS in front of it means adding your own hostname to CORS_ORIGINS in backend/.env (https://homelable.example) and restarting the service.

Configuration

All configuration is done via .env (copied from .env.example):

# Generate with: python3 -c "import secrets; print(secrets.token_hex(32))"
SECRET_KEY=change_me_in_production

# Auth — default: admin / admin
AUTH_USERNAME=admin
AUTH_PASSWORD_HASH='$2b$12$...'   # bcrypt hash — keep single quotes

# CIDR ranges to scan
SCANNER_RANGES=["192.168.1.0/24"]

# How often to check node status (seconds)
STATUS_CHECKER_INTERVAL=60

OpenID Connect (optional)

OIDC is an exclusive alternative to the local password. Existing installs stay in AUTH_MODE=local unless explicitly changed.

AUTH_MODE=oidc
CORS_ORIGINS=["https://homelable.example"]
OIDC_DISCOVERY_URL=https://idp.example/application/o/homelable/.well-known/openid-configuration
OIDC_CLIENT_ID=homelable
OIDC_CLIENT_SECRET=replace-with-a-secret
OIDC_REDIRECT_URI=https://homelable.example/api/v1/auth/oidc/callback
OIDC_SCOPES="openid profile email"
OIDC_COOKIE_SECURE=true
OIDC_SESSION_EXPIRE_MINUTES=480

Register OIDC_REDIRECT_URI exactly at the identity provider. Production OIDC requires HTTPS, a non-wildcard CORS_ORIGINS, and a confidential client. The backend uses Authorization Code with PKCE and keeps provider tokens out of the browser. SECRET_KEY must contain at least 32 bytes in OIDC mode. Do not expose OIDC_CLIENT_SECRET in Compose YAML or commit it to Git.

All settings are also editable in-app via the Scan Network button.

Development Mode

Backend (Python 3.13):

cd backend
python3.13 -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
cp ../.env.example .env       # edit SECRET_KEY and review defaults
uvicorn app.main:app --reload --port 8000

Frontend:

cd frontend
npm install
npm run dev   # http://localhost:5173
