Installation

Run YT Zero with Docker (recommended) or locally with Bun.

Requirements

Docker

• Docker
• Docker Compose

Local

• Bun 1.3 or newer

Docker

Use the published GHCR image:

services:
  ytzero:
    image: ghcr.io/pelski/ytzero:latest
    container_name: ytzero
    ports:
      - "3001:3001"
    volumes:
      - ./data:/data
    environment:
      - IDLE_TIMEOUT_SECONDS=120
      - REFRESH_INTERVAL_MINUTES=5
      - DB_PATH=/data/db/ytzero.db
      - IMG_CACHE_DIR=/data/imgcache
    restart: unless-stopped

Start it:

docker compose up -d

Or build locally from the repository:

docker compose -f docker-compose.dev.yml up --build -d

Open http://localhost:3001. Data is stored under ./data.

See Configuration for all environment variables.

Local development

Install dependencies:

bun run setup

Start backend and frontend:

bun run dev

Development URLs:

UI:  http://localhost:5173
API: http://localhost:3001

Local production-like start

bun run start

This builds ui/dist if needed and starts the backend serving the built frontend at http://localhost:3001.

Scripts

Command	Description
bun run setup	Install backend and frontend dependencies.
bun run dev	Start backend watcher and Vite dev server.
bun run dev:app	Start only the backend watcher.
bun run dev:ui	Start only the Vite dev server.
bun run build	Build the frontend.
bun run start	Serve the production frontend through the backend.

First run

After the first start you get a local YouTube subscriptions app at http://localhost:3001.

The initial app is intentionally empty: no Google login, no imported account data, and no recommendations. From Settings → Channels you add channels manually or import an OPML / Google Takeout subscriptions file (see Importing Subscriptions). Once channels are added, YT Zero starts filling a local SQLite database with their public RSS videos and background metadata.
