YouTube Colab Proxy

A feature-rich YouTube streaming proxy with a built-in web player. Watch videos, browse channels, explore playlists, and read comments — all through a clean, YouTube-inspired dark UI. Designed for Google Colab but works anywhere Python runs.

✨ Features

Video Streaming

• Proxy-based playback — streams MP4 bytes directly, no client-side extraction
• Up to 1080p support — automatically merges separate video+audio streams via ffmpeg for HD quality (works on Colab too!)
• Range requests for instant seeking and partial content delivery
• Resolution selector — choose quality or let auto-select pick the best available
• Theater & normal modes with keyboard shortcuts (Space, J/L, F)

Search & Discovery

• YouTube search with paginated results
• Channel pages — Videos tab, Playlists tab, and in-channel search
• Channel banners & avatars proxied for privacy
• Playlist viewer with numbered tracks and channel links
• Recommended videos sidebar on the watch page
• Watch history persisted in the browser

Comments

• Top-level comments with sort (Top / Newest) and adjustable limit
• Lazy-loaded replies — click to expand, no upfront cost
• Pinned & hearted badges, relative timestamps, avatars

Infrastructure

• FastAPI + Uvicorn — async, fast, production-ready
• In-memory TTL caching — streams (20 min), comments (10 min), streamlink (5 min)
• Image proxy — thumbnails and avatars routed through the server (no CORS, no tracking)
• Cookie support — file, raw string, or browser import for age-restricted / private content
• Password protection via SHA256 gate
• Google Colab integration — auto-detects Colab, generates public proxy URL

📦 Installation

From PyPI

pip install youtube-colab-proxy

From Source

git clone https://github.com/DAN3002/Youtube-Colab-Proxy.git
cd Youtube-Colab-Proxy
pip install -e .

Requirement: A JavaScript runtime (node, deno, or bun) is needed by yt-dlp for full YouTube extraction. Install one before running.

🚀 Quick Start

CLI

# Start the server
ycp --serve

# Custom host and port
ycp --serve --host 0.0.0.0 --port 8080

# With password protection
ycp --serve --password my_secret

# With cookies (age-restricted / private videos)
ycp --serve --cookies /path/to/cookies.txt
ycp --serve --cookies-str "SID=abc; HSID=xyz"
ycp --serve --cookies-from-browser chrome

Google Colab

Cell 1 — Install:

!pip install youtube-colab-proxy
!apt-get update -qq && apt-get install -y -qq nodejs

Cell 2 — Run:

import youtube_colab_proxy
url = youtube_colab_proxy.start()
# → Opens a clickable public URL in the output

With cookies:

url = youtube_colab_proxy.start(cookies_str="YOUR_COOKIE_STRING")

Note: apt-get install nodejs provides the JS runtime that yt-dlp needs. Without it, some video formats may be missing.

⚙️ Configuration

Edit youtube_colab_proxy/const.py:

PL_PAGE_SIZE = 8                    # Items per page
ADMIN_PASSWORD_SHA256 = "..."       # SHA256 hash (empty = no password)
YT_LANG = "en-US"                   # Accept-Language for yt-dlp
YT_GEO_BYPASS_COUNTRY = "US"       # Geo-bypass country code
OUTBOUND_PROXY = ""                 # Optional HTTP/SOCKS proxy

Password Protection

import youtube_colab_proxy
print(youtube_colab_proxy.hash_pass("my_password"))
# → paste the hash into const.py as ADMIN_PASSWORD_SHA256

Then start with:

ycp --serve --password my_password

🛠️ Development

# Clone & setup
git clone https://github.com/DAN3002/Youtube-Colab-Proxy.git
cd Youtube-Colab-Proxy
python3 -m venv .venv && source .venv/bin/activate
pip install -e .

# Run (auto-creates venv if needed)
./run_ycp.sh
