About this extension
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 prioritize your latest-kickoff players into FLEX spots, so you keep the option to pivot as earlier games finish.

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 — and shows you claims you've already submitted 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.

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. 7-day free trial included.

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.

NOTE: QuickManager is an independent tool and is not affiliated with, endorsed by, or sponsored by Sleeper. "Sleeper" is used only to describe compatibility.
