LeaguedIn × Sleeper: Turn every fantasy matchup into a weekly competition.
Connect your Sleeper league in seconds and start predicting.
Connect Sleeper nowHow it works (5 simple steps)
1. Connect Sleeper
Enter your Sleeper username. It's 100% read-only - LeaguedIn never changes anything in your league or on Sleeper.
2. Import your league
Pull in one (or more) of your Sleeper leagues. Rosters, matchups, and results come straight from the official Sleeper public API.
3. Wait for full lineups
Markets only open once both sides have every starting spot filled. No incomplete lineups, no shady last-second edits.
4. Predict Yes/No
Assign free Degen Dollars to weekly matchups or season futures (Champion, Top 3, etc.). Favorites return ~2x. Underdogs can return up to ~2.9x. You can't pick both sides or your own team.
5. Climb the leaderboards
Compete against your league mates (and everyone else). Rankings are based on real PNL - your starting 200 Degen Dollars never count toward your P/L.
Every manager starts with 200 Degen Dollars.
No cash value. No real-money risk. Just pure fantasy skill competition layered on top of the league you already run on Sleeper.
Make every week matter.
