NFL DFS Lineup Optimizer
Build optimal NFL DFS lineups with custom projections and stacking rules.
Turn your player pool into a set of mathematically optimal NFL lineups in seconds. Load the slate, edit projections and ownership to match your read, lock or exclude players, and generate lineups that respect every salary and roster-construction constraint at once.
NFL is a correlation game. Winning tournament lineups aren't just the highest-projected players. They're the right players stacked together so your lineup wins big when a game goes off. Seeking Optimal bakes that correlation in with QB stacking, game stacks, and defense rules so you're building structure, not just chasing points.
Whether you're entering a single-entry contest or building 150 unique lineups for a large-field GPP, you control exposure, uniqueness, and randomness while the optimizer handles the math.

How the NFL optimizer works
QB Stacking
Force your quarterback to be paired with a WR or TE from the same team, so a big passing game lifts multiple roster spots at once.
Game Stacks
Bring back an opposing skill player to capture both sides of a shootout, the structure behind most winning tournament lineups.
Avoid Opposing Defense
Never pair your DST against your own offensive players, so one game script can't work against your lineup.
Flex Control
Restrict the FLEX to the positions you want (e.g. RB/WR only) to shape roster construction to your strategy.
Exposure & Uniqueness
Cap how often any player appears across a multi-lineup build and force lineups apart for large-field GPPs.
Why Seeking Optimal
Data-driven
Start from solid projections, then bend them to your read. Edit any projection inline and the optimizer builds to your numbers.
Your judgment, amplified
Lock, exclude, stack, and cap exposure. The optimizer respects every decision you make and fills in the rest optimally.
Built for volume
Generate one lineup or a diversified multi-lineup portfolio. Export your lineups to CSV for a fast upload to DraftKings.
NFL optimizer FAQ
Does the NFL optimizer support Showdown (Captain Mode)?
Yes. Load a Showdown slate and the optimizer handles the Captain 1.5x salary and scoring multiplier and single-game roster rules automatically.
Can I use my own NFL projections?
Yes. Edit projections directly in the grid, then optimize against your numbers instead of ours.
How many NFL lineups can I build at once?
Generate anywhere from a single lineup to a large multi-lineup portfolio, with exposure and uniqueness controls to keep the set diversified.
