Real-Time Sports Betting Odds Comparison

OddsGuard is your all‑in‑one sports‑pricing companion. It delivers real‑time odds comparisons across multiple sports providers, tracks the best bonus offers, and highlights value pricing so you can make smarter decisions — all via our browser extension and web dashboard.

Once you install the extension, OddsGuard automatically scans prices from major sports platforms as you browse. It alerts you when a better value is available elsewhere or when there's a generous bonus worth claiming. The extension icon shows when you're on a supported sports provider site and highlights opportunities in real-time.

Yes — OddsGuard is completely free to use. All core features including odds comparison, notifications, and sports provider recommendations are available at no cost. Users who sign in get additional benefits like unlimited notification history and synced preferences across devices. OddsGuard is supported by affiliate links to sports providers, which helps keep the service free for all users.

OddsGuard is available as a browser extension for Firefox, with Safari and Edge support coming soon. For Chrome, Brave, and other Chromium-based browsers, we offer a free desktop application that provides the same experience. The extension automatically updates through your browser's add-on store.

OddsGuard supports 72 providers globally, including DraftKings, FanDuel, BetMGM, Bet365, Bovada, BetOnline, Caesars, Pinnacle, LeoVegas, Unibet, William Hill, Betfair, BetUS, MyBookie, Betway, and many more.
