Hey DEV community! 👋
I’ve been building a Telegram bot called @AndyVideoBot that downloads YouTube videos and audio directly to Telegram chat. No browser extension, no website, no login required — just paste a link.
What it does
- Video formats: 144p · 240p · 360p · 480p · 720p · 1080p · 1440p · 4K
- Audio: MP3 extraction
- Playlists — download entire playlists
- YouTube Shorts — vertical video supported
- Channel subscriptions — subscribe to a channel and get new uploads delivered automatically
- Dubbed audio selection — choose language when multiple audio tracks are available
- Smart cache — if someone already downloaded the same video at the same quality, instant delivery from cache (no re-downloading)
- Inline mode — share downloads directly in any Telegram chat
Tech stack
- Python 3.14 (free-threaded, GIL disabled)
- Telethon — Telegram MTProto client
- yt-dlp — YouTube downloading engine
- aiosqlite — async SQLite
Multi-bot architecture
The bot supports running multiple instances simultaneously sharing a single database. Each instance handles its own download queue, and files are served from a shared Telegram-based cache — so if bot A downloaded a video, bot B delivers it instantly from cache.
12 languages
English, Russian, German, Spanish, French, Portuguese, Turkish, Indonesian, Hindi, Vietnamese, Kazakh, Chinese.
