League-wide context

Power rankings that explain the market.

A league is an economy, not a collection of isolated rosters. rosterrr compares the same signals across every manager so you can understand relative strength, scarcity, and leverage before you send an offer.

Overall roster value

Compare dynasty value across players and draft picks to see the league hierarchy at a glance.

Position-by-position strength

See who controls quarterback, running back, wide receiver, tight end, and draft capital value.

Competitive window

Read each roster as a contender, rebuilder, or middle team using age, depth, picks, and lineup strength.

Format-aware scarcity

Superflex, 1QB, PPR, and TE premium settings change which positions create the most leverage.

League market activity

Use recent trades and value movement to understand which assets and positions your league is pricing aggressively.

Actionable next steps

Move from rankings to realistic trade partners, waiver upgrades, buy/sell windows, and team-specific strategy.

How it works

From username to league map.

The setup is intentionally light. rosterrr uses public Sleeper data, preserves your real league settings, and keeps that context connected across the entire toolkit.

Context changes the answer

What is a Sleeper dynasty league analyzer?

A Sleeper dynasty league analyzer imports the teams, players, draft picks, scoring rules, and roster settings in a league, then compares every roster in that shared context. rosterrr uses that context for power rankings, trade opportunities, waiver upgrades, and team strategy.

How does rosterrr rank teams in a dynasty league?

rosterrr compares total dynasty value, value by position, draft capital, roster construction, and competitive window. The goal is not only to name the strongest team, but to show why a roster is strong and where it can improve.

Does the league analyzer support Superflex and TE premium?

Yes. rosterrr reads the Sleeper league settings, including Superflex or 1QB, PPR level, and TE premium scoring, so the analysis reflects the format you actually play.

Can I analyze a Sleeper league without sharing my password?

Yes. rosterrr uses a public Sleeper username to read public league data. It never asks for your Sleeper password and cannot edit lineups, accept trades, or change league settings.

Does rosterrr show trade partners across my league?

Yes. It compares roster needs and available assets across managers to surface realistic partners and offers instead of treating every player as equally useful to every team.

Is the Sleeper league analyzer free?

Every new rosterrr account includes seven days of full Pro access without a credit card. Continued access after the trial costs $20 per month through PayPal.
