Dynasty Seer reads your leagues straight from Sleeper, with nothing to import. Getting in takes three steps on the sign-in page: an account, your Sleeper username, your leagues.
Steps
- Create a free account with the form at the top of the home page, or Sign in at the top of any page. Use Continue with Google, or an email and password (the confirmation email has a "Confirm my email" button; "Resend email" sends it again).
- Link your Sleeper username (the one you log in to Sleeper with) and tick the leagues to track.
- Open my leagues, then pick a league. Your team is highlighted on every page from then on.
- Used Dynasty Seer before accounts? Create a free account and link the same Sleeper username to pick up where you left off, on every device. Free covers one league; Pro covers them all.
- Switch leagues any time from the league name at the top of the screen.
- Set a default league in Settings so the app opens straight to it.
Your leagues page
- After you enter your username, the leagues page sums up every league: this week’s matchups, your combined record, playoff position and lineup problems across leagues.
- Each card shows your record and seed, playoff and title odds, roster value rank and this week’s matchup. Pin a league to keep it first, or hide a dead one.
- Your core players lists everyone on more than one of your rosters; under it, Spread your risk names the league to sell a player you lean on most (6% or more of your value, or a real asset on three rosters): the one where you’re furthest from the playoffs, or deepest at his position.
- Portfolio value: every player you own, counted once per league he’s in, priced on each daily value snapshot, with the change over the last week and a sparkline. It fills in one day at a time from when this app started keeping snapshots.
- The page leads with This week: everything to fix before kickoff in every league, then “Before waivers” (the leagues whose claims process within a day, with the time in your zone and whether your waiver plan is ready), then “AI in every league”, which runs an AI tool in all your leagues from one button: the lineup check in every league where you can still change this week’s lineup (the ones with something to fix first), the waiver plan in every league with a season still going, Trade Ideas in every league where trades are open (Pro; five deals each, from the Trade Ideas allowance: the same request the Trade Ideas page sends, never repeating your last five runs there), and the weekly recap and the power rankings’ blurbs (Pro) for last week. The league cards follow, then “Across your leagues”: the biggest games of the week (with each game’s swing player), how your leagues compare, and your core players, one tab at a time. Each league is one run from your AI allowance; the button says how many it will start and asks first, and if you have fewer runs left than leagues it starts that many and names the rest. Each tool’s answers show under its button, one line per league with the gist (the swaps, the top claims, the deals, the recap with a Copy button) and a link to the full answer on that league’s page; they stay there after you leave, and the bell lists the whole run as one entry, with one alert when the last league is in.
- “Your core players” are the players you roster in more than one league, with their share of your total value.
No Sleeper league?
Use "Try the demo" on the home page (no account needed) to look around a real 12-team superflex league, with made-up names. It opens as one of its teams; Switch team in the banner at the top picks another.
