WhoUnfollowedMe - GitHub Follower Tracker

Introduction

WhoUnfollowedMe is a simple yet powerful GitHub follower tracker that helps you monitor and analyze changes in your GitHub account followers. This application allows you to easily identify new followers, detect unfollowers, and track your follower trends over time.

Key Features

• Check current followers of any GitHub account
• Detect new and lost followers between checks
• Save follower history for long-term analysis
• Compare follower data between any two points in time
• Export/import data for backup or transfer to other devices
• Filter and export data by time range (24 hours, 7 days, 30 days, or custom)
• Support for Personal Access Token for accounts with many followers

How to Use

Checking Followers

1. Enter a GitHub username in the search box
2. (Optional) Enable "Use GitHub Token" for accounts with many followers
3. Select "Update new data from GitHub" to fetch fresh data, or "Use saved data only" to view existing data
4. Click "Check" to display results

Viewing Followers

• All tab: Shows all current followers
• New tab: Displays users who started following since the last check
• Lost tab: Shows users who unfollowed since the last check
• History tab: View and manage your follower history

Comparing Data

1. Go to the "History" tab
2. Select two time points from the history list to compare
3. Click the "Compare" button to see the changes

Export/Import Data

• Export: Click "Export Data" and choose a time range (all, 24 hours, 7 days, 30 days, or custom)
• Import: Click "Import Data" and select a previously exported .json file

How It Works

The application uses the GitHub API to fetch the follower list of an account. Data is stored locally in your browser (localStorage), allowing tracking of changes over time. No GitHub login is required, though using a Personal Access Token is recommended to avoid API rate limits and access data for accounts with many followers.
