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

- 01
Every violation type that matters
Empty starting slots, starters on bye, players ruled Out or on IR left in lineups — flagged per roster, per week, with the player and slot named.
- 02
A season-long paper trail
The season feed keeps every violation on record, so "he always does this" stops being a feeling and starts being a count.
- 03
Inform log for commissioners
Track who you’ve already nudged about a broken lineup, so the Tuesday reminder never turns into a Thursday argument about who knew what.
- 04
Points left on the bench
Quantifies the damage: how many points a manager’s bench outscored their starters by. Ideal for end-of-season awards and public shaming.
- 05
Live before kickoff, forensic after
Run it pre-lock to catch fixable problems while they’re fixable, or after the week to document what happened for the record.

Fine print
Questions, answered
Does it catch lineups before games lock?
Yes — the live view flags empty slots, bye-week starters, and injured players while there’s still time to fix them, using current NFL schedule and injury data.
Do I have to be the commissioner?
No. Anyone in the league can audit lineups. Commissioner-specific features like the inform log are there for whoever has to actually enforce the rules.
Does it message my leaguemates?
No. Commisherable never posts to your league or messages anyone. The inform log tracks your own follow-ups; delivering the bad news is still your job.
How far back does the season feed go?
The full current season — every violation, by manager and week, with historical bye and injury context reconstructed for past weeks.
