This application is not designed or intended to be run on a public-facing URL. There is no authentication, no user management, and no security hardening. Run it exclusively on your local network or behind a VPN. Do not expose it to the internet.

This project was built entirely through AI prompting using Claude — no manual code was written by the author. AI can and does make mistakes, and this application is not perfect. Bugs should be expected.

The author does not take any credit for the features and technologies that make UnTube function — all credit goes to the open-source projects this app is built on: yt-dlp, Flask, React, and others.

You are free to modify, improve, and adapt this project in any way you like. Use at your own risk.

A Docker-based web application that lets you follow YouTube channels, automatically download their videos, and watch them in a clean, ad-free interface — all on your own hardware.

• Docker and Docker Compose

docker pull tomfriart/untube:latest

Then create a docker-compose.yml:

services:
  untube:
    image: tomfriart/untube:latest
    container_name: untube
    ports:
      - "3987:80"
    volumes:
      - ./data:/app/data
      - ./downloads:/app/downloads
    restart: unless-stopped

docker compose up -d

# Open in your browser
open http://localhost:3987

git clone https://github.com/tomfriart/untube.git
cd untube

docker compose up -d --build

# Open in your browser
open http://localhost:3987

docker compose down

UnTube runs as a single Docker container combining the frontend and backend, managed by supervisord.

All settings are adjustable from the Settings panel in the UI:

Per-channel overrides for quality and auto-delete are available from each channel's settings.

By default videos are saved to ./downloads/ next to the docker-compose.yml. To point at an existing media library, edit the backend volume in docker-compose.yml:

volumes:
  - /your/media/path:/app/downloads

• Videos not downloading? Check logs: docker compose logs untube
• yt-dlp errors? YouTube frequently changes its internals, which breaks yt-dlp. This is the most common source of issues and is outside this project's control. When it happens, rebuild the image to get the latest yt-dlp: docker compose build --no-cache (or docker pull tomfriart/untube:latest if using Docker Hub). Expect this to be needed every few weeks.
• Disk space? Monitor ./downloads/ — higher quality = bigger files; enable auto-delete in Settings

• Backend — Python, Flask, yt-dlp, APScheduler, SQLite
• Frontend — React 18, Vite, hls.js
• Serving — nginx (reverse proxy + static files)
• Packaging — Docker Compose
