Linked Sleeper handles auto-load on visit. Your default format and data source travel with you, too.
Power Pulse, Positional WAR, and the Lineups projections behind every league here all run on the same engine. See how FF Beacon's numbers are put together.
The tool
Sleeper's own app shows you one league at a time and one team at a time. League Pulse pulls every league your username is in onto one page, then opens each into a full read of the rosters, the trades, and who is really on course to win.
Yours, or anyone's. Sleeper's league data is public, so no account and no password are involved. Sign in once and your handle is saved, and the page loads by itself next time.

Each row is a league: name, team count, roster shape and season. Once a league has been opened, the row also shows how your own team stands in it, so a six-league Sunday starts with the team that needs you most.
Every roster with its values, every trade graded, the transaction feed, week by week matchups, and the lineup helper. Everything is read from your league's own scoring settings, so a superflex TE premium league is scored as one.
Two rankings, two questions. The trade-value ranking says who owns the most. Power Pulse says who should win the most games from here, built from weekly projections run against the real remaining schedule.
A 1 to 99 score for how many games each team should win from here, ranked inside your league only. Draft picks are ignored on purpose: a 2028 first cannot start on Sunday.
Positional WAR shows how fast each position runs out in your league. A steep line means the drop from the best starter to the next one is big, which is where your budget and your trades should go.
FAQ
Each of your teams gets a one-word status from its projected wins and what its roster is worth, so the list sorts the teams that can win this year to the top. A one-year league reads Longshot where a dynasty one reads Rebuilder.
A league is refreshed from Sleeper when you open it and then held for a while, so a reload is instant. Commissioners get a refresh button for the moment a trade goes through.
You need a Sleeper username to look up, and nothing else. League Pulse reads the same public league data the Sleeper app shows anyone with the link. It never asks for a password and cannot change anything in your league.
Yes, if you know a username in it, because the data is public on Sleeper. The page is built for your own leagues, though, and the team status column only means something for a team you manage.
Your league's own. Every number inside a league view is calculated from that league's actual scoring settings and roster slots, not from a generic PPR table. The only thing you choose is the value source used for player prices.
The team status and the rankings are calculated the first time a league is opened, because calculating them for leagues nobody looks at would be wasted work. Open it once, or press Sync on the row, and it fills in.
Not today. League Pulse reads Sleeper's public API, and Sleeper is the only major host that publishes league data openly. The manual tools on the site, the trade calculator, the FAAB calculator and the start/sit tool, work for any league.
