I built a GitHub star monitor in a single YAML file — zero dependencies, zero config

GitHub doesn't notify you when someone stars your repo. Or unstars it. You either refresh your profile page like a maniac, or you just... never find out. Tools like star-history.com let you look up trends, but you have to visit the site every time. GitHub Apps like Star Notifier automate it, but now a third-party service is handling your tokens. Self-hosted solutions like github-star-notifier need a server running somewhere. I wanted something automatic that requires zero infrastructure . So I built it using nothing but GitHub Actions. What it does GitHub Star Checker monitors star counts across all your public repositories and notifies you when stars change — gains or losses. Runs every hour by default (configurable from the GitHub UI) Sends alerts via GitHub Issues or Gmail Generates weekly and monthly reports All logic lives in a single workflow file No server, no database, no dependencies — just one YAML file and GitHub's free compute. How it works A cron job triggers every hour on
