More than a calculator
Every tool follows the same league context.
A fair trade is not automatically a useful trade. rosterrr keeps your format, depth chart, competitive window, picks, partner needs, and league market attached to the decision from start to finish.
Trade analyzer + counters
Test both sides, understand fairness and roster impact, then repair close offers with realistic counters.
Trade finder
Find managers whose needs and available assets line up with yours instead of guessing who to message.
Waiver and roster upgrades
Surface free agents who improve your real depth chart and expose weak positions before the league does.
AI dynasty war room
Turn your league context into practical strategy, trade pitches, veto checks, and player news summaries.
Read-only Sleeper connection
Connect with a public Sleeper username. We never ask for your Sleeper password or change your team.
Format-aware by default
The settings matter. So does your timeline.
Quarterbacks, tight ends, draft picks, and aging veterans do not carry the same weight in every league. rosterrr reads the format and helps you act like a contender, rebuilder, or team caught in between.

Common questions
Before you connect Sleeper.
Does rosterrr connect directly to my Sleeper dynasty leagues?
Yes. Sign in with a verified email or Google account and link a public Sleeper username. rosterrr loads the dynasty leagues, rosters, picks, settings, transactions, and available players associated with that profile.
Is this different from a generic dynasty trade calculator?
A generic calculator compares asset totals. rosterrr also considers your actual league format, the teams involved, positional strength, draft capital, competitive window, partner needs, and the assets each manager can really trade.
Does it work for Superflex and TE premium?
Yes. rosterrr reads the league configuration and uses format-aware values and recommendations for Superflex, 1QB, PPR, half-PPR, standard, and TE premium leagues.
Can rosterrr make trades or lineup changes for me?
No. The Sleeper connection is read-only. rosterrr gives you analysis and recommendations; you remain in control of every action in Sleeper.
