Follower Snapshot Tracker

Save local Instagram relationship snapshots and compare observed changes across accounts. Import JSON or collect visible lists.

## Follower Snapshot Tracker Follower Snapshot Tracker helps you save and compare Instagram follower and following lists over time. Create local snapshots of visible relationship lists, compare them later, and review observed changes in a simple dashboard. The extension is designed for users who want a clearer way to organize follower data without sending their collected information to an external service. ### Key Features * Collect visible Instagram followers or following lists * Save multiple snapshots for different accounts * Compare earlier and later snapshots * See newly observed profiles * Identify profiles that were not seen in a later snapshot * Search collected usernames and comparison results * Export collected data as CSV or JSON * Export comparison results as JSON * Import supported Instagram relationship JSON files * Pause, resume, or stop an active collection * Keep snapshot history stored locally in your browser ### Compare Follower Snapshots Save a follower or following list today and create another snapshot later. Follower Snapshot Tracker compares the two collections and highlights changes between them. Comparison results are shown as observed differences. A profile that is not present in a later snapshot should not automatically be considered a confirmed unfollow, since incomplete lists, account changes, or Instagram loading behavior may affect the results. ### Local Data Storage Collected profiles and saved snapshots are stored in the browser's local extension storage. The extension does not send your follower history to an external backend or require a separate account. You can export your data whenever you want and remove saved snapshots directly from the dashboard. ### Import Existing Relationship Data Already downloaded your Instagram information? You can import supported followers or following JSON files and use them to create snapshots for comparison. Imported data is processed locally on your device. ### Designed With Clear Limitations Follower Snapshot Tracker works only with information that is accessible to you. It does not bypass private accounts, login challenges, platform restrictions, or hidden information. Instagram controls how relationship lists are displayed and loaded, so collections may sometimes be incomplete. ### Independent Tool Follower Snapshot Tracker is an independent browser extension and is not affiliated with, endorsed by, or sponsored by Instagram or Meta. Use the extension only for data you are authorized to access and process.
