Fetch YouTube Comments

• Available for macOS, Linux & Windows
• Fetch all comments + comment replies for a given list of YouTube videos
• Applies cooldown if rate limit reached
• Outputs CSV file containing all comments

Usage

A YouTube API key is required. You can get one here.

1. Download executable

Download the latest executable for your system.

• Windows: fetch_comments_windows.exe
• macOS: fetch_comments_mac
• Linux: fetch_comments_arm64

If you get a permissions denied error, you may call sudo chmod +x fetch_comments.

2. Create a videos.txt

Create a videos.txt file with the YouTube video URLs you want to fetch comments from (separated by new line) in the same folder as the executable.
