The finder checks the leagues tied to your Sleeper username, so it needs an account to know which ones are yours. It is free, and you only set it up once.
Pick a player below. This sample runs against invented leagues so you can see what a real search returns before you connect your own.
The backup running back is a free agent in 3 of your 5 searched leagues, and rostered in 2.
1 more league was not searched, because no rosters are stored for it yet.
A running back gets hurt in the early game and his backup is the name everyone is typing. Here is what finding out where he is free costs you.
Nine leagues means nine waiver pages and the same name searched nine times.
The tool
Sleeper, like every fantasy platform, shows you the free agents for one league at a time. If you play in several, the honest answer to 'is he available in any of my leagues?' means opening each waiver page and searching the same name again. The Free Agent Finder reads the rosters of every Sleeper league tied to your username and tells you, in one search, where the player is still free and where somebody already has him.
Nine leagues, one Sunday
Our Discord is full of people in the same position, comparing notes on who is free where and what he is going for, free to join.

One search. The two leagues where he is free are already at the top.
search
Sign in and save the username you use on Sleeper. Every tool on FF Beacon then knows your leagues and stops asking.
Pick him from the list as you type. Defensive players are in there too, for leagues that start them.
Every synced league answers at once. The ones where he is available sit at the top in green; the rest stay underneath with who has him and in which slot.
Each row opens that league. From there the FAAB calculator can price the bid against that room's budgets.
Every player is on one of its rosters or he is not, and not on a roster is free agency. There is no separate free agent list to go stale.
Because it is. The result says which slot he is in, so you know whether he is gone or parked somewhere you might pry him loose from.
With no rosters stored, everybody would read as free. Those leagues are counted as unanswered instead, so a blank never sends you to a waiver page for nothing.
FAQ
It answers one question that nobody can answer from inside a single league: given one player's name, which of your leagues still have him unowned. A manager in fourteen rooms who hears a name on Sunday morning would otherwise have to open fourteen waiver pages to find the two where he is sitting there free. This asks it once.
Sign in, save your Sleeper username once, then type a player's name into the search box on this page and pick him from the list. Every synced league you are in answers at the same time, with the leagues where he is available at the top. Each row links straight into that league.
A league is a closed world. Every player is either on one of its rosters or he is not, and not on a roster is free agency. So the check is whether that player appears anywhere in the league's stored rosters, and the answer is the complement. Injured reserve and taxi squad players count as rostered, because they are, and the result says which slot a rostered player is sitting in.
Only for leagues we already hold. Any of those last read from Sleeper more than an hour ago is refreshed before the search, up to 12 per search with the oldest first, so a player claimed this morning shows as taken. A league nobody has opened on FF Beacon yet is not pulled in. It is reported as unanswered rather than as a yes, because with no rosters to be absent from, every player in the world would read as free. Press Sync all in My Beacon and those leagues join the next search.
For the multi-league search, yes, because it runs against the leagues tied to the Sleeper username saved on your account. There is an account-free version of the neighboring question though: open any Sleeper league in League Pulse and its lineups page lists that league's free agents, ranked against the roster you are looking at.
No. It reads Sleeper leagues only, because Sleeper is the platform that publishes league rosters openly.
Your platform can only ever answer for the league you are currently looking at. The point of this is the comparison across all of them at once, which is the version of the question a multi-league manager actually has.
Every league tied to your saved Sleeper username, up to a cap of 200 that exists so one search cannot turn into an unbounded scan.
