Guess the Line
LiveA free NFL prediction game I built for my friends. Each week everyone picks the spread and total for every game. Closest to the number scores. No money involved.


What it does
- Weekly picks for every game, with a deadline and reminders.
- Standings and season history for each group.
- Private games: create one, invite friends, settle disputes as commissioner.
- A community feed for posts and comments.
What I built
- Web app hosted on Cloudflare Pages.
- Accounts and data in Supabase, with Google sign-in.
- Game lines pulled in on a schedule, plus kickoff weather.
- Browser push reminders before each deadline.
- Light and dark themes.

Sign-in, a database, scheduled data and reminders are the same parts I use for client tools.
