What dynasty fantasy football trade analyzer works with Sleeper leagues?

Can rosterrr evaluate trades in Superflex and TE Premium leagues?
Yes. rosterrr reads Sleeper league settings and adjusts analysis for formats such as Superflex, 1QB, PPR, half-PPR, standard scoring, and TE premium scoring.
Does rosterrr need my Sleeper password?
No. rosterrr only uses public Sleeper league data from a Sleeper username or league ID. It does not ask for or store a Sleeper password.
What can dynasty fantasy football managers use rosterrr for?
Managers use rosterrr to compare dynasty trade value, find trade partners, build counter offers, identify buy/sell windows, review roster strengths and weaknesses, and scan free agents for waiver value.
Is rosterrr free to try?
Yes. Every new manager gets seven days of full Pro access without a credit card. After day 7, a $20 monthly PayPal subscription is required to keep using rosterrr.
