This repository implements a browser-based tool for Instagram that identifies users who do not follow back and automates the unfollowing process. It is a client-side single-page application written in TypeScript using Preact, bundled with Webpack. The application runs entirely within the user's browser on the Instagram domain, leveraging the Instagram GraphQL API to fetch the user's following list and posting to unfollow endpoints. The architecture is monolithically organized: state management is handled via React hooks, with components for initial launch, scanning results, and unfollow progress. Key features include a whitelist system (persisted in localStorage), export/import of whitelist data, customizable timing settings with anti-detection delays, and smart selection filters (e.g., select verified, private, no profile pic). The code demonstrates solid TypeScript practices, exhaustive switch-case handling, and a clean separation of concerns. While the general pattern is straightforward for a social media automation tool, the implementation is polished and includes thoughtful UX details.
