Common questions
Which dynasty fantasy football platforms does rosterrr support?
rosterrr supports Sleeper, MyFantasyLeague, Fleaflicker, Fantrax, and publicly viewable ESPN leagues through read-only league-ID connections. ESPN support is a best-effort public beta because its fantasy data endpoint is undocumented. rosterrr does not ask for a league-platform password or receive permission to change your league.
What analysis does rosterrr provide for every supported league?
Every supported connection can produce league power rankings and team comparisons from the roster and draft-pick data the platform makes available. rosterrr normalizes those leagues against the same dynasty market so managers can compare teams in context.
Which features are currently available for Sleeper leagues?
Sleeper connections include the cross-platform rankings and comparison experience plus the expanded owner workspace for roster analysis, trade partners, counter offers, waiver ideas, market context, and AI-assisted strategy.
Does rosterrr need my fantasy-platform password?
No. Public-league connections use a league ID, and rosterrr receives no permission to change a league. Where an authorized connection such as Yahoo is available, sign-in happens with the platform and rosterrr never receives the platform password.
