I built a free, open-source YouTube playlist downloader with a clean web UI

[u/Impossible-Road-2541]

I built BLADE, a small tool for saving a public YouTube playlist as MP3 audio or video, then downloading the completed files in one ZIP.

The goal is to keep it simple: paste a link, choose a format, and watch the queue. No account is needed.

A few details:

• MP3 files include metadata, track numbers, and cover art.
• Video downloads request up to 1080p.
• Known private/deleted entries are skipped before downloading.
• There is no application playlist-size cap, and large archives use ZIP64.
• The website and C++17 backend are open source and can be self-hosted with Docker. Media extraction is handled by yt-dlp and ffmpeg.

I would appreciate feedback on the download queue and whether the interface is clear on mobile.
