QuickManager: Fantasy for Sleeper tekijä QuickManagerFantasy

Managing one Sleeper league is easy. Managing ten is a chore. QuickManager turns hours of repetitive, league by league clicking into a few clicks that run across every league you're in, all from one dashboard.

WHAT IT DOES

Mass Lineup Optimizer
Scan every league at once, see exactly how many points you're leaving on your bench, and apply optimal lineups everywhere with one click. Pick any week; bye weeks and projections are handled automatically. Optionally push the players whose games kick off last into your FLEX spots, so you keep the option to pivot as earlier games finish.

Player Portfolio & The Gameday Board
On Sunday morning you don't need a list of everyone you own. You need the two or three lineups that still need a click. The Gameday Board puts every lineup you manage in one place, sorted by kickoff, and shows only what actually needs a decision: an upgrade worth making, a starter who's been ruled out, an empty slot nobody is filling. Every suggestion names both players, the slot it affects, and what the change is worth in that league's own scoring. Apply one on its own, or tick the ones you agree with and push them to every league at once. Anything whose game has already started is marked as locked and never suggested, so you're never offered a change that can't happen. Injury tags sit on every row with the body part and practice report one click away, and when a starter is out and nothing on your bench is eligible for that slot, it says so plainly instead of quietly leaving the row off the list. The season long view is still here too: every player you own across every league, how many of your teams he's on, and which of those leagues are realistically still alive.

Waiver Wire Tools & The Waiver Board
Add the players you want to a single target list and see instantly which of your leagues each one is actually available in. QuickManager builds an editable claim for each. Change the drop from a dropdown, or add your own fallback attempt if your first plan doesn't land. Claims you've already submitted show up right there too, with a true total exposure number against your budget. The Free Agent Radar surfaces the highest projected unowned players across your whole portfolio, filterable by position, and Mass Drop cuts a player from every league you own them in with one click.

Trade Factory & Open Trades
Define a trade and scan all your leagues for valid partners. Review every pending trade offer across all leagues in one place, and accept, decline, or withdraw in a single click. Counter or modify any offer and optionally send a Sleeper DM with the trade attached so the other manager actually sees it. Before you pull the trigger, the Trade Impact Simulator runs thousands of simulated seasons for both rosters to show what a deal genuinely does to each side's playoff odds, with an optional injury and depth model that reveals how fragile a star for scrubs trade really leaves you.

Matchups & Power Rankings
See this week's matchup and win probability for every league at once, then run a full season simulation to find out which leagues are still genuinely in play. Power Rankings shows real simulated playoff odds, not just a guess, and a table across every league ranks each roster by how much attention is actually worth spending on it right now. Dig into any single league for a fan chart of the whole simulated season, a breakdown at every position against the rest of your league, and real standings with a lucky versus unlucky signal built in.

Roster Health
Every league gets checked against its own IR and taxi squad rules. Move everyone eligible onto IR in one pass, and if a roster ever breaks its league's own rules (a healed player still parked on IR, one too many players rostered), QuickManager finds it automatically and fixes what it can without cutting anyone. If a cut is genuinely unavoidable, nothing is dropped without your say so.

BUILT FOR SPEED
Everything runs in parallel across your leagues, so scans that used to mean dozens of manual steps finish in seconds.

FREE VS PRO
Every feature is fully usable for free for five leagues, so you can see exactly what the tool does before paying anything. Pro unlocks all your leagues at once, with 7 days free to start.

PRIVATE BY DESIGN
Your Sleeper login token never leaves your device. There is no QuickManager server collecting your data. The extension talks directly to Sleeper from your own browser.
