Free NFL Lineup Optimizer
One slate a week, and a whole week to attack it. Build cap-legal DraftKings and FanDuel rosters around a quarterback stack, with Vegas numbers and injury status sitting on every row of the pool.
How do I build a free NFL DFS lineup?
Open the NFL lineup builder, pick DraftKings or FanDuel, and it fills a cap-legal roster from our projections. Building is free without an account and the one-click presets include a QB stack. Custom stacking, roster rules and exposure caps are Pro.
What the optimizer does
NFL scoring is correlated through the quarterback. Presets build the stack for you. Pro lets you pick the stack size and which pass catchers count, then bring back a piece of the opposing offense. Defenses facing your own stack are blocked automatically.
Implied team total, spread, and game total sit next to each player, so you can see which offenses the market expects to score before you lock anything in.
Game-status designations show on the row. Hide anyone Out, Doubtful, or on IR in one click instead of scanning the pool by hand.
Free accounts build up to 5 lineups and set a minimum number of unique players between them. Pro builds up to 50 and caps how often any one player appears.
DraftKings and FanDuel are not the same contest
Same nine roster spots, different math. A lineup that fits one site is usually illegal on the other, so pick your site first and the optimizer switches the rules underneath you.
| Rule | DraftKings | FanDuel |
|---|---|---|
| Salary cap | $50,000 | $60,000 |
| Receptions | 1 point (full PPR) | 0.5 points (half PPR) |
| Roster spread | At least 2 games | At least 3 teams |
| Single-game captain | CPT at 1.5x | MVP at 1.5x |
The reception rule is the one that quietly reshapes a pool. Full PPR pushes pass-catching backs and high-volume slot receivers up the board; half PPR pulls them back toward touchdown scorers.
Weekly, not daily
An NFL slate is a week of news, not a morning of it. Practice reports, inactives, and line movement all land between the time the board opens and the time it locks, so the useful move is to build early, then re-run once the late information arrives rather than trying to get it right in one pass.

Common questions
- Is it free?
- Building lineups is free and needs no account. Sign in with a free account to set lineup uniqueness or save a lineup. Custom QB stacking, roster rules and exposure caps are Pro.
- Can I stack a quarterback with his receivers?
- Yes. Every preset builds around a QB stack. With Pro you set the stack size, which positions count, and the bring-back yourself. The optimizer also blocks a defense playing against your own stack.
- Does it handle showdown and single-game slates?
- Yes. The single-game builder applies the 1.5x captain multiplier to both salary and projected points, and labels the slot CPT on DraftKings or MVP on FanDuel.
- How many lineups can I build at once?
- Up to 5 per build with a free account (2 without an account, 50 with Pro). Pro also lets you cap exposure for the whole set or for individual players before you re-run.
