The toolkit

Three tools. Zero group-chat polls.

Each one turns a league argument into a screenshot. Pick the fight you're currently losing.

01Scoring Calculator

Test the rule change before the league yells at you.

Pull your real Sleeper league, tweak any of 147 scoring settings, and watch the whole season re-score in place. Who gains, who falls, and which matchups would have flipped.

  • Rank shifts
  • Matchup flips
  • Season replay

02Lineup Auditor

Someone started a player on bye. Again.

The Lineup Auditor sweeps every roster in your Sleeper league each week for empty slots, injured starters, and bye-week ghosts, and keeps the season-long receipts a commissioner actually needs.

  • Weekly sweep
  • Live risk flags
  • Season ledger

03Manager Intel

Run the background check before the invite.

A stranger wants your open spot. Manager Intel reads three seasons of their public Sleeper record, career ledger, rings, lineup reliability, and activity, and hands you a verdict you can quote in league chat.

  • Career ledger
  • Reliability score
  • Activity signal
