Nineteen sportsbooks and four prediction market exchanges, one board. Every tool below runs on the same live prices and the same de-vigged fair-value math. No picks, no card, no signup for the boards. Math, not picks.
There are no paid features in the app. Nothing is for sale. The board refreshes hourly for everyone, and live prices are free: enter an email and it refreshes every minute. No payment, no account, no password.
Everything on this page is free right now. The finding tools will eventually move to a paid tier; the comparison board stays free forever. Join the beta with your email and you keep founder terms whenever pricing starts. No card, no catch, cancel nothing because there is nothing to cancel.
In-play moneyline, spread, and total across every book while the game runs, refreshed every minute with per-card timestamps and suspended-market states.
Every book's moneyline, spread, and total on every game, side by side, best price flagged.
Every player, every milestone, best price per line and the book that has it, with alt lines behind every row.
Season-long markets across every book that posts them, grouped FanDuel-style with the best price per outcome.
Build any parlay and see which book pays the most on the whole ticket, with per-leg best prices and deep links that prefill the slip where the book supports it.
PrizePicks, Underdog and DK Pick6 lines graded against the sportsbook market's de-vigged fair price.
Both sides of the same game at different numbers, so a result in the window wins both tickets.
Scans every book pair on the board for guaranteed-profit prices, games and player props, with the exact stakes to place.
Six modes: hedge any bet, convert a free bet to cash, work a profit or odds boost, clear a no-sweat bet or wager requirement, hedge a parlay leg by leg, or hedge a futures ticket across the whole field.
Log a bet once and it syncs across your devices, settles itself from final scores, and captures your closing line value automatically.
Save the profit boosts your books give you, fine print included.
Eleven calculators, no account: EV, arbitrage, hedging, futures hedge, parlay, Kelly, teaser, middle, hold, no-vig, and an odds converter.
Name your price on any game and market, moneyline, spread, total, even first-5-innings, and get a push notification the moment any book we track hits it.
/odds in any server: best price ladders for any bet, today's +EV plays, pick'em grades, middles, hedges, and parlay pricing.
Every board above is free forever at an hourly refresh. One email unlocks the Live Beta: the 60-second board, full +EV lists, DFS grades, middles, price watch pushes, tracker sync, and automatic CLV. No card. Math, not picks.
