Dozor

Dozor is a live surebet scanner for esports. It reads odds from 27 bookmakers and two prediction exchanges, normalizes them into one format, matches the same event across books and shows every arbitrage opportunity with its ROI, both outcomes and a link straight to the bookmaker.

Coverage is 21 titles, CS2 and Dota 2 the busiest of them, across 35+ market types: winners, map totals and handicaps, rounds and kills. Live and prematch sit in one list behind a toggle, and every row shows how long the surebet has existed and how many seconds ago the price moved.

The calculator splits a stake so the payout is identical whichever side lands, and it accounts for bookmaker currency, stake rounding and exchange fees. A middles calculator, rule-based alerts on your own ROI and bookmaker thresholds, a per-match odds table and a bet journal with profit tracking round it out.

Free plan shows surebets up to 1% ROI forever, no card. PRO unlocks everything from $1.42 a day and can be paused for up to 14 days. Analytics only - Dozor does not take bets and does not guarantee profit.
