How It Works

Enter Your Roster

Add each player by name, select their position, and enter the consensus projection for this week. Use the Load Sample button to see a realistic 14-player roster instantly.

Optimize Automatically

Click Optimize Lineup to fill every starting slot (QB, 2 RB, 2 WR, TE, FLEX, K, DST) with the highest-projected eligible players. The algorithm respects position limits and maximizes total projected points.

Compare Alternatives

Each filled slot shows your next-best option. Click any alternative to swap it in and see the updated projection instantly. Great for weighing injury risk, weather, or matchup preference.

Export & Save

Download your lineup as JSON (for tools) or CSV (for spreadsheets). Your roster persists in this browser so you can return next week and just update projections.
