About Instagram Unfollowers

Instagram Unfollowers is an open-source, browser-based tool that checks which Instagram accounts do not follow a user back. Desktop users copy the project's code, log in to Instagram on the web, paste the code into the browser's developer console, and run a scan; accounts appear on screen as batches are fetched, and completed scans are cached locally so they can be reloaded without a new API call. On Android, the same steps are performed through the Eruda browser app.

Scans list accounts, allow whitelisting of specific users (with JSON export, import, and bulk paste), and let users tick accounts to unfollow. Requests are made to Instagram's web endpoints, and the project describes session headers, an action-block guard, rate-limit backoff on HTTP 429 or 400 responses, and a lock that prevents unfollows if a scan is interrupted to reduce the risk of forced logouts or blocks. The project says all processing happens locally in the browser and that no credentials or data are sent to its own servers, but scanning and unfollowing still rely on Instagram's services. Pricing is not stated.
