What Rafterlore is
Rafterlore is a free, non-commercial fan project that shows the history of fantasy basketball and football leagues hosted on Sleeper. There are no payments, ads or paid features.
Not Sleeper
Rafterlore works with Sleeper leagues but is not affiliated with, endorsed by or sponsored by Sleeper. Sleeper is a trademark of its owner. League data comes from Sleeper's public API.
Accuracy
We try to get every number right, but Rafterlore is provided as is, without guarantees. Official records and points-for totals come straight from Sleeper. Weekly matchup scores, head-to-head records, trade grades and lineup numbers are built from Sleeper's weekly data, which doesn't always match the official totals; those are marked “per Sleeper”. Don't settle bets with them.
Fair use
- Don't try to overload the site or Sleeper, or get around the limits on importing leagues.
- Don't scrape Rafterlore in bulk.
- Only remove a league you manage.
We may limit or block access that breaks these rules.
Your league
Any manager can remove their league from Rafterlore: use the “Remove it from Rafterlore” link at the bottom of your league's page. We may also remove a league or change or stop the service at any time.
Changes
If these terms change, we'll update this page and the date at the top.
