Dynasty Trade Maker is built specifically for Sleeper — no other platform gets the same level of integration. Here's exactly what happens when you connect your league, and what you unlock once you do.
Sleeper's API is public and read-only for league data, which means you connect with just your Sleeper username — never a password, never an OAuth login screen. Click Import Your League, enter your username, and every dynasty league tied to that account loads automatically.
No password. No OAuth. Just your username.
Sleeper's public API means your credentials are never shared with us.
Your whole roster gets real values instantly
Every player on every team in your league is priced against the live dynasty chart.
The AI Trade Analyzer knows your actual team
Pick a strategy — Win Now, Balanced, or Rebuild — and it generates six full trade packages built from real rosters in your league.
Trade Finder scans your whole league in one click
Surfacing trades where both sides actually improve.
Contender Rankings tell you who's buying and who's selling
Every team scored 0-100.
Draft War Room pulls your real draft board
Including traded picks, with pick-by-pick AI advice and a mock draft simulator.
Sleeper is the default platform for most competitive dynasty leagues, and dynasty formats (especially Superflex, TE Premium) shift value in ways a generic redraft tool won't catch. Because we pull your actual league settings on import, every value and suggestion you see already accounts for your specific format.
Do I need to make an account?
No — importing a league to see roster values, rankings, and the free Trade Calculator requires nothing. An account is only needed if you want to save settings or go Pro.
Is my Sleeper data ever written back or changed?
No — the connection is read-only.
What if I'm in more than one dynasty league?
All of them load under your one Sleeper username — switch between leagues from your dashboard.
Import your Sleeper league in under a minute. See what's free vs. Pro.
