As answered by people managing Learn JavaScript and Dynasty Dealer.
Dynasty Dealer's answer:
It's the only major dynasty trade calculator that blends two signals transparently: real Sleeper trade prices (recalculated every 12 hours) and community votes that are disclosed, capped, and shown per player. Competitors pick one side — KeepTradeCut is pure crowd-vote, FantasyCalc is pure algorithm. Dynasty Dealer uses both, shows its work, and publishes head-to-head studies measuring its values against what managers actually trade for.
Dynasty Dealer's answer:
Because you get the full picture, not half of it. A pure crowd tool tells you what people feel; a pure algorithm tells you what trades happened — Dynasty Dealer combines them and is honest about how. On top of the calculator you get player pages with a real recent-trade tape, an AI trade assistant, a live trade database, Sleeper league sync, and original-data studies — a complete toolkit, not just a single number. The core is free, with native iOS and Android apps.
Dynasty Dealer's answer:
Dynasty fantasy football managers — players in keep-your-roster-year-round leagues (overwhelmingly on Sleeper) who trade actively and want an objective, data-backed second opinion before proposing or accepting a deal. It spans newer managers learning player value and veterans fine-tuning contender or rebuild rosters, across Superflex, 1QB, and TE-Premium formats.
Dynasty Dealer's answer:
Dynasty Dealer was built by founder Elliot Pollaro out of frustration that the popular trade calculators relied on either crowd opinion or an opaque algorithm — and constantly disagreed with each other. The idea was simple: price players from what managers actually pay in real Sleeper trades, blend in transparent community input, recalculate around the clock, and then prove it by publishing how those values hold up against real trade outcomes. It's grown into a full dynasty platform — calculator, rankings, AI assistant, trade database, and mobile apps.
Dynasty Dealer's answer:
React (web) and React Native / Expo (iOS & Android apps), Node.js serverless functions on Vercel, and MySQL / TiDB for the trade and value data. It integrates directly with the Sleeper API for league sync and feeds real trade data into a proprietary value engine that recalculates every 12 hours.
