The GitHub Follower Notification App does exactly what it sounds like: it tells you when someone new starts following your GitHub account and when someone stops following you. If you've ever wondered who dropped you after a project shipped or who picked you up after a popular commit, this tool keeps you in the loop automatically. The app connects to your GitHub account through a standard sign-in process, the kind where you click a button, approve a request, and let the app read your follower list. Behind the scenes it's built with a web framework called Rails, and it checks your follower list periodically to see what's changed. When someone new appears or a previous follower disappears, it sends you a notification so you don't have to manually compare lists yourself. This is most useful for people who have a meaningful public presence on GitHub, maintainers of open source projects, developer advocates, educators who share course repos, or anyone whose professional reputation is partly tied to their GitHub footprint. If you only have a handful of followers, the value is limited. But if you're running a repo with real traction and want to understand how your audience is growing or shrinking over time, this gives you a simple signal without much effort on your part. The README is quite sparse, so it doesn't go into detail on how notifications are delivered, how often checks happen, or what customization options exist. There's a link to the live app and a separate documentation page for those who want to dig further. One thing worth noting: the app runs on Heroku, a platform for hosting web applications, which means availability depends on whether the developer keeps that hosting active.
