Marginfold

Best for: Bettors who price lines and want the lowest margin

Pinnacle built its name on thin margins and a welcome for sharp bettors. We check what that reputation rests on, what it costs to withdraw, and where you cannot use it.

Best for: Price-conscious, higher-staking bettors who value limits over features

Circa Sports skips welcome offers, takes bigger bets than most US books and says it does not ban winners. We weighed that against a bare app, thin banking and a three-and-a-half-star store rating.

Best for: UK bettors who want to compare bookmaker prices before every bet

Oddschecker compared prices long before apps copied it. With OC+ now free, we looked at what you get without paying, what the old tiers cost, and how affiliate offers shape the page you start from.

Best for: Experienced bettors who want to back and lay at exchange prices

Betfair Exchange lets you back and lay against other bettors and pays a commission on net winnings. We worked through the maths against a bookmaker line, and what the 2025 fee change means.

Best for: High-volume prop and futures bettors who want models

Unabated sells props, simulators, DFS entry building and an odds API from $99 a month. We look at the plan ladder, the free calculators and who earns that fee back.

Best for: Live bettors who already hold an account at a larger US book

bet365 is a British giant with one of the deepest in-play menus anywhere and a US footprint much smaller than DraftKings or FanDuel. We weighed live markets, early payouts and its payout record against reach.
