What each one is built for
BetWatch is a free odds screen and line movement tracker. It covers 38 sportsbooks across 29 leagues, including DraftKings, FanDuel, BetMGM, Caesars, bet365, Fanatics, ESPN BET, BetRivers, Hard Rock Bet, theScore Bet, Fliff and Pinnacle, the prediction markets Kalshi, Novig and ProphetX, and the pick'em apps PrizePicks, Underdog, Sleeper, Dabble, ParlayPlay and DraftKings Pick6. Every price change at every book is recorded, from the opening line to the close. Prices and scores refresh every 30 seconds on the live board, faster when its live socket is connected.
OddsJam is built for profit-hunting at scale: scanners that flag positive expected value bets and arbitrage across dozens of books, promo converters, and a bet tracker. It is aimed at bettors who place a high volume of edge bets.

Pick OddsJam if
- You want software that scans every book for +EV and arbitrage opportunities and alerts you.
- You bet at high volume and the subscription pays for itself in edge.
- You use sportsbook promos and want tools built to convert them.
Questions
Is there a free alternative to OddsJam?
Yes. BetWatch is free during its beta and covers the odds-comparison and line-movement side of what OddsJam does: 38 sportsbooks side by side, the best price highlighted, and the full line history of every game. It does not run an automated arbitrage scanner.
How much does OddsJam cost?
As of September 2026, OddsJam Gold is listed at about $199.99 a month and Platinum at about $499 a month, with a 7-day free trial. Check oddsjam.com for current prices.
Does BetWatch find +EV bets like OddsJam?
For pick'em props, yes: the Fantasy Optimizer compares PrizePicks, Underdog, Sleeper, Dabble and ParlayPlay lines against sharp sportsbook prices and flags the +EV ones. For regular sportsbook markets, BetWatch shows every book's price and the consensus so you can spot an outlier, but it does not scan and alert the way OddsJam does.
Can I use BetWatch and OddsJam together?
Yes. Some bettors use a scanner to find a bet and BetWatch to check how the line has moved at each book before they place it.
