uld-cli 1.0.1

Unified Local Downloader - A single CLI for torrents, magnet links, videos, and direct downloads

ULD - Unified Local Downloader

A single CLI tool for downloading content from multiple sources: torrents, magnet links, video platforms, and direct URLs.

Why ULD?

Today, downloading content requires juggling multiple tools:

• Torrent clients for torrents/magnet links
• yt-dlp for YouTube/videos
• wget/curl/aria2 for direct files

Each has different CLI syntax, progress formats, and configuration. ULD provides:

• Single interface - One command for all download types
• Auto-detection - Automatically routes to the right engine
• Unified progress - Consistent progress display across all downloads
• Local-first - Runs entirely on your machine, no cloud dependencies

Installation

pip install uld-cli

# Using uv (recommended)
uv add uld-cli

Includes both torrent (libtorrent) and video (yt-dlp) engines out of the box.
