X Follower Tracker — dcoder

X Follower Tracker lets you save a snapshot of your followers and compare it later to find out who unfollowed you — and who's new.

HOW IT WORKS

1. Go to x.com/{your_username}/followers
2. Click the extension icon and hit "Save Current Followers"
3. Come back anytime, open the same page, and click "Check for Unfollowers"
4. See exactly who left and who's new since your last save

FEATURES

• Detects unfollowers by comparing your current follower list with your saved baseline
• Shows new followers gained since the last save
• Uses X's internal API when available — works even if you switch tabs
• Falls back to page scanning automatically if the API is unavailable
• Handles rate limits gracefully with automatic retry
• Click any username in the results to go directly to their profile

PRIVACY

• Zero data collection — nothing is sent to any server, ever
• Your follower list is stored locally in your browser using browser.storage.local
• No account creation, no login, no tracking
• Fully open source (MIT License)
