Outlier is best known for us bettors new to arbitrage who want a simple interface, but no single scanner is right for everyone. The most common reasons bettors switch are account limiting at the books Outlier relies on, a need for wider bookmaker coverage, a lower entry price, or a specific feature like a built-in promo converter, live in-play arbs, or a developer API. The picks below cover each of those angles.
