I built a free YouTube/SoundCloud downloader for Windows that runs entirely on your PC

Description and use

A simple Windows app that downloads video and audio from over 1000 sites, including YouTube, SoundCloud, Vimeo, TikTok, etc., without ads or third‑party servers. Runs entirely locally, supports playlists, music search, subtitles, and proxy.

Problem

Users need a single tool to download videos from many sites without ads, pop‑ups, or third‑party servers.

Outcome

A single, ad‑free Windows application that downloads videos and audio from over 1000 sites, supports playlists, music search, subtitles, and proxy usage, all running locally without installing Python system‑wide.

Workflow

• Download universal-downloader.zip from the GitHub release.
• Unpack the zip and double‑click Запуск.bat to start the app.
• Paste a link into the UI to download the desired format or playlist.
• Optionally use the Music tab to search and download by name.
• Use the browser extension or bookmarklet to trigger downloads from any page.
• Configure proxy settings if needed.
• Use the built‑in player to preview audio tracks.
• Uninstall via Удалить.bat when finished.

Evidence

I built Universal Downloader, a free, open‑source Windows app on top of yt-dlp.

Source

Everything happens on your computer. The UI is just a local web page, served by a tiny Flask server that listens on 127.0.0.1 only.

Source

On first start a small script downloads a private copy of Python 3.12, yt-dlp, ffmpeg and Deno into the app folder and verifies every download with SHA-256.
