UdemySaver is an open-source Udemy course downloader written in modern C++20. It lets you save videos, subtitles, and course assets you own for offline learning. A built-in HTTP server powers a responsive web interface so you can browse your Udemy library, queue downloads, and monitor progress from any browser.

• Download Udemy courses, lectures, subtitles, and attachments for offline access.
• Responsive web interface to browse your Udemy library.
• Queue and monitor downloads for single lectures or entire courses.
• Automatically organizes files under a structured downloads/ directory.
• Cross-platform build via CMake for Windows, macOS, and Linux.

git clone https://github.com/jadis0x/UdemySaver.git
cd UdemySaver
cmake -S . -B build
cmake --build build

Create a settings.ini alongside the executable:

# UdemySaver settings
# http_proxy=http://127.0.0.1:8080   ; optional
udemy_access_token=PASTE_YOUR_TOKEN_HERE
udemy_api_base=https://www.udemy.com
download_subtitles=true
download_assets=true   

You can also start the program without a token and paste it via the web interface; the file will be created automatically.
