LeagueBarn
A live stats site for your Sleeper league
Sleeper runs your league. LeagueBarn gives it a home — standings, power rankings, draft grades, and trade grades on one link, updated automatically all season.
No password needed. We read your league; we never write to it.
What you get
- Live standings and matchups, synced from Sleeper.
- LBPI power rankings — a single number that captures who’s actually playing well.
- Draft grades for every pick, and trade grades for every deal.
- Rivalry history, waiver-wire tracking, and all-time awards and records.
How the import works
Sleeper’s league data is public and read-only, so there’s no password and no permissions screen to grant. Search your league by your Sleeper username, pick it from the list, and choose which seasons to bring in — LeagueBarn pulls your rosters, matchups, transactions, and draft straight from Sleeper’s API. You’ll sign in with Google once at the end, only to save the league to your account; that’s identity, not a Sleeper login, and it grants no posting or publishing access. From there, your league’s current season refreshes automatically every hour.
What we read, what we never write
We read your league’s public Sleeper data and, once you sign in, your name/email/Google account ID to know the league is yours. We never ask for a Sleeper password, never post to your league, and never change a roster or a setting.
Frequently asked questions
Do I need my league password?
No — Sleeper’s league data is public and read-only, so there’s no password to give. The only sign-in involved is Google, once at the end, just to save the league to your account.
Where do I find my Sleeper league ID?
You don’t need one. Search by your Sleeper username instead — LeagueBarn lists every league tied to that username for the season you pick, and you choose the right one from there.
Can I import seasons from before we moved to Sleeper?
Not automatically yet. LeagueBarn can walk your league’s full Sleeper-side history (Sleeper links each season to the one before it), but typing in seasons from a platform you left behind isn’t built yet — see our League History page for where that’s headed.
Does LeagueBarn change anything in my league?
No. LeagueBarn only ever reads your league’s data. It never posts to your league, changes a roster, or touches a setting — there’s nothing in the product that writes back to Sleeper or ESPN at all.
Is LeagueBarn free?
Yes, free while we’re in beta. If we introduce paid plans later, existing leagues get notice first.
Who can see our league page — is it public?
Yes — your league’s page (yourleague.leaguebarn.com) is public to anyone with the link, the same way your league is already visible on its platform. Your personal account info (email, name) is never shown on it.
What happens when the season ends?
Once your season is marked complete, that year’s standings, draft grades, and trade grades stop changing and become part of your league’s permanent record. LeagueBarn’s automatic sync only touches the current, in-progress season.
