Free MLB Lineup Optimizer
Daily MLB slates with our projections already attached, turned into cap-legal DraftKings and FanDuel lineups with stack presets, locks, and exclusions.
How do I build a free MLB DFS lineup?
Open the MLB lineup builder, sign in with a free account, and it fills a cap-legal DraftKings or FanDuel roster from our projections — no card required.
What the optimizer does
MLB runs daily. Main and single-game slates load with our projections and salaries ready to optimize.
Our projections refresh several times a day through the season, so you're not optimizing on stale morning numbers.
Presets build a stack for you. Pro lets you set the primary stack and cap hitters per team. The optimizer keeps every lineup roster-legal on DraftKings and FanDuel.
Lock your pitcher and exclude anyone you don't trust. With Pro you also cap exposure across a full lineup set before you re-run.

Common questions
- Is it free to use?
- Yes. Sign in with a free account and build up to 5 lineups at a time. No card required. Pro raises that to 50 and adds custom stacks, roster rules and exposure caps.
- Does it work for both DraftKings and FanDuel?
- Yes. Pick your site in the builder and the roster slots, salary cap, and scoring rules switch to match.
- Can I build stacks?
- Yes. The one-click presets build team stacks for you. With Pro you choose the primary stack and cap hitters per team yourself. Every lineup stays legal on either site.
