QuickManager: Fantasy for Sleeper

Manage all your Sleeper fantasy football leagues at once: mass lineup optimizer, waiver tools, and cross-league trades.

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 Target any player and instantly see which of your leagues they're available in. Set FAAB bids and drops, then submit claims across leagues together. The Free Agent Radar surfaces the highest-projected unowned players across your whole portfolio, filterable by position. - 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 — no more hunting league by league. 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 on one league, so you can see exactly what the tool does before paying anything. Pro unlocks all your leagues at once with a 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. IDP leagues: Individual Defensive Player support is built in and will switch on automatically once Sleeper publishes IDP projections.
