Betsurf by Betsurf

Betsurf helps sports bettors maximize their winnings by automatically detecting and comparing odds from multiple sportsbooks directly on match pages.

It currently supports several major Swedish bookmakers including Expekt, Unibet, Bet365, Leovegas, and others. The extension injects a lightweight interface that highlights better odds found on competing platforms.

To retrieve up-to-date odds, Betsurf sends basic match data (teams, start time, and bookmaker) to an external API. A random, anonymous UUID is also included by default for usage metrics — users can opt out of this in the settings.

No personal or identifying user data is collected. All interface and site preferences are stored locally.
