Single-page dashboard built directly in HTML, CSS, and vanilla JavaScript. It also uses Google Identity Services for sign-in, Leaflet for map pins, and a small service worker + web manifest so it behaves like an installable PWA.

The backend is a small Python service powered by Flask with Flask-CORS. Production serving is set up for Gunicorn, and the scheduler work is handled inside Python instead of splitting into separate services.

SQLite stores users, per-account settings, tracked products, and check history. APScheduler runs recurring stock checks in the background for each signed-in account.

Product resolution and stock lookup use requests, BeautifulSoup, and lxml. When hits are found, the app pushes alerts through Discord webhooks.
