About FolScan – Instagram Follower Tracker
Scan Followers, Following or both and build your own history of what changed.
🔍 SEE WHO CHANGED
FolScan builds and maintains its own chronology based on changes FolScan can reliably observe with subsequent scans, rather than relying on Instagram to provide an order it no longer supplies. This means you will always see who is new and who left, every time you do a new scan and FolScan will remember the order that they arrived since your first scan.
FolScan creates a snapshot of an Instagram profile's follower relationships. Scan again later to discover what changed:
• 📉 Lost Followers — See who unfollowed between scans
• 👥 New Followers — See who started following
• 💔 Not Following You Back — Find one-way follows
• 🚫 Unfollowed — See accounts you or the analyzed profile stopped following
• 📈 New Followings — See newly followed accounts
• 🤝 Mutual Followers — Find accounts with mutual relationships
• 📊 Follower Changes — Track follower and following growth over time
Choose to scan Followers, Following or both, so you only scan the data you need.
When scanning both, FolScan retrieves Following first because it can usually be collected more efficiently.
If your network connection is interrupted during a scan, FolScan can pause and let you resume instead of immediately abandoning the scan. FolScan can also retain useful observations from incomplete scans to help subsequent scans recover missing data.
🔒 PRIVACY FIRST
FolScan works with your existing Instagram browser session.
• No Instagram password required
• Follower and following lists stay locally in your browser
• No FolScan cloud database stores your follower lists
• Scan history and comparisons are maintained locally
🆓 START WITH A FULL SCAN
Your first successful scan can create a complete baseline, giving FolScan a starting point for future comparisons.
Once a baseline exists, later scans can identify individual relationship changes rather than simply showing changes in follower counts.

📅 BUILD YOUR OWN INSTAGRAM HISTORY
Instagram shows you what your audience looks like now. FolScan helps you understand what changed between your scans.
Your first successful scan creates a baseline. Future scans can then reveal:
Who followed → Who unfollowed → Who changed username → Who you followed → Who you unfollowed → How your audience changed
Previous reports remain available for comparison.
🚀 GET STARTED
1. Install FolScan and log in to Instagram in your browser
2. Open FolScan from the Chrome toolbar
3. Run your first full scan to create your baseline
4. Scan again later to discover what changed
For the most reliable experience, use FolScan with your own Instagram account.
Third-party profile scanning is experimental, particularly for profiles with large follower lists. Instagram may temporarily limit requests, and larger follower lists require more requests to analyze. FolScan detects incomplete scans rather than presenting incomplete data as a complete result.
Start free with your first full scan. Upgrade to Premium or Premium Pro for continued scanning, advanced analytics, management and interaction tools.
