Free · no signup · public Sleeper data
Audit your Sleeper roster.
See what the market got wrong.
Paste your Sleeper username. You get your real roster back with an FFT model rank and a consensus ADP next to every player, the strongest buy and fade on your own team, the raw measured numbers behind each call, and your positional strength against your league’s actual replacement level.
What it needs from you
Your Sleeper username — the one in Sleeper under Account, not your display name and not your team name. Nothing else. If you are in more than one league you pick which roster to grade. If your league has not drafted yet, we say so instead of grading an empty team.
How it works
- 01
We read your public Sleeper roster
Your username resolves to your leagues, and your leagues resolve to the exact players on your team. Read-only, public data, no password. Nothing is written back to Sleeper and nothing is stored here.
- 02
We price every player against YOUR league's replacement level
Your team count and your actual starting slots are read off the league and used to compute replacement level, so a 12-team two-flex VORP is not a 10-team superflex VORP. One thing we do NOT yet do: per-reception scoring does not move the base projection, because the player spine stores one projection per player rather than per-stat components. Every audit says so on the page rather than letting you assume otherwise.
- 03
We say where the market and our model disagree
Consensus ADP across Yahoo, Sleeper and RTSports on one side; an ADP-independent projection on the other. Where they diverge you get a BUY or a FADE, and every call carries the measured red-zone, Next Gen Stats, route-concept and volume numbers behind it.
What it will not do
Read this before you argue with your league about the output. We would rather you know the limits up front than discover them in a number you trusted.
Most of your roster will come back ALIGNED
That is the honest answer. The draft market is largely efficient, and a tool that finds an edge on every player is measuring player quality and calling it insight. On our full board, the majority of players are ALIGNED.
Players we did not measure are named, not graded
Rookies have no prior NFL season, so they carry none of our four signals and appear on no board. Deep bench players fall outside our 335-player draft spine. Both are reported as unmeasured with the reason, never as a zero.
We beat naive baselines, not the market
Our projection model outperforms 'repeat last season' and positional averages in a published backtest. No test in this repository shows it beating draft-market pricing, and we will not imply otherwise.
