A league analyzer for Sleeper dynasty leagues
Type your Sleeper username and pick a league. Dynasty Seer reads the league’s public history and tells you who makes the deals, who is contending, who is rebuilding, and where your own team is thin.
The scouting report on every owner is free and needs no account. It never asks for your Sleeper password and cannot change anything in your league.
Only your Sleeper username: never your password, and no account needed. A league link or id works too.
The league, every team in it, and yours
The owner report below is free without an account. The rest opens with a free account, for one league on the Free plan.
- Every owner
- A scouting report on each league-mate from the league’s own history: who starts trades and who waits for offers, how fast they accept, the positions they keep buying, how they draft and how they bid.
- Power rankings
- A weekly ranking that blends record (40%), points for (35%) and roster value (25%), with a line on each team and how lucky its record is against its scores.
- Playoff odds
- The rest of the season played out 3,000 times: each team’s chance to make the playoffs, earn a bye and win the title, and the record you need the rest of the way.
- Each team’s window
- The Trade Block labels every team Win now, In between or Rebuilding, and shows the positions where each has too many or too few startable players.
- Your team
- Roster value now and over the next two seasons from each position’s age curve, your position groups against the league average, and who to sell before the drop.
- Roster audit
- Dead roster spots, IR and taxi slots you aren’t using, and bye-week pileups, for your team or the whole league.
- Trade history
- Every trade the league has made, priced at today’s values, with who came out ahead and the points each side’s players went on to start.

Questions
Is there a league analyzer for Sleeper dynasty leagues?
Yes. Dynasty Seer analyzes a Sleeper league from your username: a scouting report on every owner, power rankings, playoff odds, each team’s window and needs, and your own roster. The owner report is free and needs no account.
Do I need to give my Sleeper password?
No. Your Sleeper username is enough. Dynasty Seer reads public league data only and cannot set lineups, send trades or change anything in your league.
Does it analyze my team or the whole league?
Both. The league view covers every owner, the standings, power rankings and playoff odds. Your team’s page covers its value now and over the next two seasons, its position groups against the league, and a roster audit.
Which league formats does it work with?
Sleeper leagues: dynasty, keeper, redraft, best ball and guillotine, 1QB or superflex, with TE premium and any scoring. The settings are read from Sleeper, so there is nothing to fill in. Dynasty leagues get the most from it.
How much history does it read?
Every season the league has been on Sleeper, up to seven. Each read about an owner says how much history it rests on.
Is it free?
The scouting report on every owner is free without an account. A free account opens one league. Pro opens every league you are in, every owner’s full report and more AI analyses.
