This is a browser bookmarklet that scans Instagram follower and following lists to identify accounts that do not follow back. It runs entirely as client-side JavaScript injected into the Instagram web page, extracting relationship data from the DOM and comparing it locally without any server-side processing or external API calls.
The tool includes adjustable timing controls to set custom delays between scanning actions, helping to avoid triggering Instagram's security rate limits during large list comparisons. It also provides a whitelist management system that stores excluded accounts as a JSON file, which can be exported, imported, and merged across browser sessions to protect specific users from unfollow detection.
The bookmarklet approach means no browser extensions or additional software installations are required, and all data processing happens within the browser session.
