Deploying yt-dlp Web UI

Introduction

yt-dlp Web UI provides a user-friendly browser interface for yt-dlp, the popular command-line video downloader. Instead of memorizing complex command-line options, users can paste URLs, select formats, and manage downloads through an intuitive web interface.

Built to make yt-dlp accessible to everyone, the Web UI maintains the full power of yt-dlp while presenting it in a graphical format. Users can download videos from thousands of supported websites, choose quality settings, extract audio, and monitor download progress all from their browser.

Key highlights of yt-dlp Web UI:

• Browser-Based: Access from any device with a web browser
• Easy Downloads: Paste URL, select options, and download
• Format Selection: Choose video quality, audio format, and more
• Download Queue: Manage multiple downloads simultaneously
• Progress Tracking: Real-time download progress and status
• History: View past downloads and re-download files
• Audio Extraction: Extract audio from videos easily
• Playlist Support: Download entire playlists or individual videos
• Subtitle Downloads: Fetch available subtitles automatically
• Mobile Friendly: Responsive design for phones and tablets
• Open Source: Multiple implementations available

This guide walks through deploying yt-dlp Web UI on Klutch.sh using Docker, configuring the interface, and managing video downloads.

Why Deploy yt-dlp Web UI on Klutch.sh

Deploying yt-dlp Web UI on Klutch.sh provides several advantages:

Simplified Deployment: Klutch.sh automatically detects your Dockerfile and builds the Web UI without complex configuration. Push to GitHub, and your interface deploys automatically.

Persistent Storage: Attach persistent volumes for downloaded files. Your videos survive container restarts and redeployments.

HTTPS by Default: Klutch.sh provides automatic SSL certificates for secure access from anywhere.

GitHub Integration: Connect your configuration repository directly from GitHub. Updates trigger automatic redeployments.

Scalable Resources: Allocate CPU and memory based on download frequency and video sizes.

Environment Variable Management: Securely store configuration through Klutch.sh’s environment variable system.

Custom Domains: Assign a custom domain for easy access and sharing.

Always-On Availability: Your download interface remains accessible 24/7 from any device.

Prerequisites

Before deploying yt-dlp Web UI on Klutch.sh, ensure you have:

• A Klutch.sh account
• A GitHub account with a repository for your configuration
• Basic familiarity with Docker and containerization concepts

Understanding yt-dlp Web UI Architecture

yt-dlp Web UI typically consists of these components:

Web Server: Serves the frontend interface and handles user interactions. Usually built with Flask, FastAPI, or Node.js.

yt-dlp Backend: The actual yt-dlp binary that performs downloads. Executes commands based on user selections.

Download Manager: Tracks download progress, manages queues, and handles concurrent downloads.

File Storage: Organizes downloaded files and serves them for access or additional download.

Database (Optional): Stores download history, user preferences, and queue state.

Preparing Your Repository

To deploy yt-dlp Web UI on Klutch.sh, create a GitHub repository containing your configuration.

Repository Structure

yt-dlp-webui-deploy/
├── Dockerfile
├── config.json
├── README.md
└── .dockerignore

Creating the Dockerfile

Create a Dockerfile using a popular yt-dlp web interface:

FROM python:3.11-slim

# Install system dependencies
RUN apt-get update && apt-get install -y \
    ffmpeg \
    git \
    curl \
    && rm -rf /var/lib/apt/lists/*

# Install yt-dlp
RUN pip install --no-cache-dir yt-dlp

# Clone a popular web UI (using alexta69/metube as example)
WORKDIR /app
RUN git clone --depth 1 https://github.com/alexta69/metube.git .

# Install Python dependencies
RUN pip install --no-cache-dir -r requirements.txt

# Create directories
RUN mkdir -p /downloads /config

# Set environment variables
ENV UID=1000
ENV GID=1000
ENV DOWNLOAD_DIR=/downloads
ENV STATE_DIR=/config
ENV TEMP_DIR=/tmp

# Expose web port
EXPOSE 8081

# Health check
HEALTHCHECK --interval=30s --timeout=10s --start-period=20s --retries=3 \
  CMD curl -f http://localhost:8081/ || exit 1

# Start the application
CMD ["python", "app/main.py"]

Alternative: Using Docker Hub Image

For simpler deployment, use an existing image:

FROM alexta69/metube:latest

# Set environment variables
ENV UID=1000
ENV GID=1000
ENV DOWNLOAD_DIR=/downloads
ENV STATE_DIR=/config

# Create directories
RUN mkdir -p /downloads /config

# Expose web port
EXPOSE 8081

Configuration Options

Create a config.json file for additional settings:

{
  "download_dir": "/downloads",
  "temp_dir": "/tmp",
  "max_concurrent_downloads": 3,
  "default_format": "bestvideo[height<=1080]+bestaudio/best[height<=1080]",
  "keep_archive": true,
  "embed_metadata": true,
  "embed_thumbnail": true,
  "add_subtitles": true
}

Creating the .dockerignore File

Create a .dockerignore file:

.git
.github
*.md
LICENSE
.gitignore
*.log
.DS_Store
.env

Create a New Project on Klutch.sh

Navigate to the Klutch.sh dashboard and create a new project. Name it something descriptive like “ytdlp-webui” or “video-downloader”.

Create a New App

Within your project, create a new app. Connect your GitHub account and select your yt-dlp Web UI repository.

Configure HTTP Traffic

The web interface serves over HTTP:

• Select HTTP as the traffic type
• Set the internal port to 8081

Set Environment Variables

Configure optional environment variables:

Variable	Value
UID	1000
GID	1000

Attach Persistent Volumes

Add persistent storage for downloads:

Mount Path	Recommended Size	Purpose
/downloads	100 GB	Downloaded video files
/config	1 GB	Application state and history

Deploy Your Application

Click Deploy to start the build process. Klutch.sh will:

• Build the container image
• Install yt-dlp and ffmpeg
• Attach the persistent volumes
• Start the web server
• Provision an HTTPS certificate

Access the Web UI

Once deployment completes, access your yt-dlp Web UI at your deployment URL. No login is required by default.

File Browser Integration

If you need to manage files more extensively, consider deploying a file browser alongside yt-dlp Web UI that points to the same download volume.

Volume Access

Files are stored in the persistent volume at /downloads. The file structure typically follows:

/downloads/
├── Video Title.mp4
├── Another Video.webm
└── Playlist Name/
    ├── Video 1.mp4
    └── Video 2.mp4
