Desktop-grade linear programming optimizer — fully functional on widescreen desktop displays, tablets, and phones.
Never be locked into someone else's player predictions. CleanSlate DFS lets you upload custom CSV projections from any source — RotoGrinders, FantasyLabs, SaberSim, or your own custom spreadsheet models.
When starting lineups change 10 minutes before kickoff or tip-off, you don't need a bulky laptop. CleanSlate DFS recalculates optimal pivots across every unlocked player in your active DraftKings and FanDuel entries with a single tap.
Never get caught with a scratched player in your starting lineup again. CleanSlate monitors real-time official injury reports and inactive announcements across NFL, NBA, MLB, NHL, and PGA. The second an active player in your entries is ruled OUT, an actionable notification lands directly on your lock screen with 1-tap late swap recommendations.
Stop wondering why your lineups missed the cut. CleanSlate automatically pulls final contest scores, cash bubbles, and mathematical optimal ceilings so you know whether your process won or lost.
Choose any DraftKings or FanDuel slate across NFL, NBA, MLB, NHL, or PGA. Use default projections or upload your own custom projection CSV file.
Lock core plays, cap exposure percentages, and apply smart QB+WR+Opponent game stacks. Build 1 to 150 mathematically optimal lineups in milliseconds.
Download your lineup file ready for 1-tap entry into DraftKings or FanDuel. Follow games live and execute on-the-go late swaps from anywhere.
