Create your league, then send us its history. We load it by hand for now, so a new league shows as pending until we do.
Sleeper
NextLeague ID only, no password. Past seasons chain back automatically.
ESPN
Works todayCreate your league here, then paste your ESPN league's address in its settings. We load every season ESPN still has, with each week's lineups. Private leagues also need two sign-in cookies from a league member; settings walks you through it.
CSV history
Works todayHow the demo leagues were built. Export once, and every season you have ever played becomes material.
