What's inside

Built for players who
take DFS seriously.

Every feature is designed around one question: what actually helps you win? No noise, no filler.

Core
Finds the optimal lineup within your constraints — salary cap, exposure limits, locked players, and stacking rules — automatically.
Simulations
Runs hundreds of scenarios per slate to surface lineups built to hold up across a wide range of outcomes.
Market-Validated Projections
Our model is backtested against thousands of real player outcomes — and measurably out-predicts the closing salary the market sets. Sharp where it counts.
Batting Order Enforcement
Unconfirmed hitters are automatically removed once lineup orders post. You only build with players who are actually in the game.
SLATEBREAKER Model
Our signature projection model — rebuilt from real results until it beat the market, not tuned by guesswork. The edge you can verify.
Sharp only
Picks Intelligence
Top plays by position, the best stack on the slate, and low-ownership contrarian targets — all in one view before you build.
Sharp only
CSV Export
Export all lineups in the exact format FanDuel and DraftKings accept. Drop it in and enter.
Cash + GPP Modes
Cash mode builds safe, high-floor lineups for 50/50s. GPP mode stacks and chases upside for tournament play.
Park + Matchup Factors
Venue effects, recent hot streaks, and favorable matchups are factored in automatically. The details are handled.

How it works

Sharp lineups in
four steps.

SlateBreaker handles the hard part. You set your constraints and click run.

01
Data loads automatically
Vegas lines, projections, batting orders, and ownership data are pulled automatically on page load.
02
Select your slate
Pick your platform, contest type, and slate. Unconfirmed players drop off automatically as lineups post.
03
Set your edge
Lock in your anchors, fade players you hate, and set how much you want any one player to appear across your lineups.
04
Run and export
Up to 150 unique lineups ranked by projected score. Export and upload directly to FanDuel or DraftKings.
