What is OddsGuard?
OddsGuard is a free AI-powered odds comparison browser extension that overlays real-time sportsbook prices directly onto the betting page you are already on, so bettors can line-shop without switching tabs. Built for sports bettors who want the best price on every wager, OddsGuard compares odds across 75+ sportsbooks and bookmakers and stamps a live savings badge on each odds button, showing how much more a bet pays elsewhere before you tap. Core features include instant line shopping, +EV (positive expected value) alerts that flag mispriced markets, parlay comparison to maximize combined payouts, and bonus tracking. The extension installs on Firefox, Safari, Windows, and Mac, requires no registration, and carries no subscription. OddsGuard also compares your book's price against multiple odds aggregators and surfaces the best available line first. The tool discloses that it earns affiliate commissions when users sign up or bet with partner sportsbooks, but states commissions never influence price rankings — the best price is always ranked first. For bettors focused on long-term edge, seeing per-bet savings (for example, better pricing worth an extra amount per $100 staked) helps quantify the value of shopping lines rather than betting on the first book they open.
