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 and exposure caps are free without an account; sign in to add QB stacking and roster rules.
What the optimizer does
NFL scoring is correlated through the quarterback. 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.
Build up to 20 lineups, cap how often any one player appears, and set a minimum number of unique players between them.
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 add QB stacking, roster rules, and lineup uniqueness, or to save a lineup.
- Can I stack a quarterback with his receivers?
- Yes. Set the QB stack size and which positions count toward it, then add a bring-back from the opposing offense. 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 20 per build. Cap exposure for the whole set or for individual players before you re-run.
