RotoCore

NFL DFS lineup optimizer

Pull any DraftKings NFL contest, set your rules, and build up to 150 optimized lineups in minutes.

why rotocore?

RotoCore is a focused tool for one job: turning a DraftKings NFL player pool into a set of lineups you actually want to enter. No spreadsheets, no manual entry.

Live contest data + game odds

Select a contest and the optimizer syncs the current DraftKings player pool: salaries, positions, injury status, and game odds. Edit projections, lock or exclude players, set stacks and exposure limits, then build anywhere from 1 to 150 unique lineups and export a DraftKings-ready CSV.

powerful customization tools

stacking

QB stacks with one to four pass catchers, RB + DST stacks, and a cap on players from the opposing team. Control how many lineups carry each stack.

exposure limits

Cap how often any player, or any position, shows up across your build. Lock a core play into every lineup or fade a player entirely.

lineup rules

Set minimum salary, minimum unique players between lineups, team diversity limits, and a volatility control that adds randomness for tournaments.

edit, review, export

Adjust projections in the player grid, review each build in an interactive lineup editor, compare runs, and download a DraftKings-ready CSV.

ready to

Free accounts build up to 20 lineups. The season pass unlocks 150 lineups, stacking, exposure limits, and CSV export for one payment.
