Import from Sleeper
Paste a league id and we read its scoring settings, its lineup slots and its rosters straight off Sleeper's public API, translate them onto our stat catalog, and show you exactly what came across before anything is created.
Your scoring, our five seasons of numbers, no spreadsheet in between.
Importing creates a league and a scoring system, so it needs an account. Reading everything already here does not.
Sign inWhat gets created. A scoring system named after your league, the league itself on the 2025 season, one team per Sleeper roster with its players signed, and a 14-week round robin. Lineups are left empty, because Sleeper's roster is one week's lineup and copying it into every week would be fiction. Set them on a team page, or press the best-lineup button and let the solver do it.
Why 2025. The lab holds 2021 through 2025, so that is the last season an imported league can actually be scored against. 2026 goes live once the season kicks off and its stats start landing.
What we cannot carry. Anything Sleeper scores that our stat catalog has no column for is listed by name after the preview rather than dropped quietly, and so is any player we could not match. Everything else is yours to edit: the imported scoring system is a normal one, so open it in the builder and change whatever you like.
