A complete history of your roster — what you traded, where each pick landed in the draft, and who it became. The one place to easily look back on the deals that built your team and reflect on what could have been.
Follow each traded draft pick forward to the exact slot it became and the player taken there — even after it changed hands several times.
Every trade you and your leaguemates have made, across every season, shown as an honest record — not a black-box grade.
Your current squad with ages, the picks you hold for upcoming drafts, and standings going back through your league's history.
See how every traded player performed before vs. after the deal, scored to your league's exact settings.
It's a complete, honest history of your Sleeper dynasty league. It reads your public league data and shows you every trade you've made, traces each traded draft pick to the exact player it became, and lays out your rosters, standings, and how past deals have played out. Think of it as an almanac for looking back — not a grader or a projection tool.
Sleeper shows you the present. The Almanac shows you the whole story: where every traded pick landed, who it became, how players performed before versus after a trade, and what your roster would look like after a hypothetical deal. It's built for reflection and history, the stuff that's hard to piece together yourself.
No. You just enter your Sleeper username. The Almanac only reads publicly available league data — it never asks for your Sleeper password and never posts or changes anything. You create an account with us (by email or Google) purely to manage your access.
Deliberately, no. We don't do fake-confident grades. Instead we show you the facts — what each pick became, how the players performed afterward, how your roster shifts — and let you draw your own conclusions. Honest record-keeping over hot takes.
$5/month, or $15/year (launch price — usually $19.99). Every new account gets a 24-hour free trial so you can explore your whole league history before deciding. Cancel anytime.
