Questions & Answers

As answered by people managing The Odds Gap.
  1. Why should a person choose The Odds Gap over its competitors?

    Many odds tools paywall the comparison, skip the newer prediction-market exchanges, or make money selling picks. The Odds Gap keeps the core comparison free forever, includes the exchanges with their fees baked into the displayed price, and never sells picks. You get the whole stack in one place: line shopping, +EV plays graded on a public record against the de-vigged Pinnacle line, hedging and arbitrage, DFS pick'em grading, and a tracker that captures your closing line value automatically. One free email unlocks the live 60-second in-play board. If you want honest numbers and tools instead of tips behind a paywall, that is the fit.

  2. How would you describe the primary audience of The Odds Gap?

    US sports bettors who care about getting the best number: line shoppers, value and +EV bettors, hedgers and arbers, DFS pick'em players, and anyone curious about the new prediction-market exchanges. It spans casual bettors who just want the best price on tonight's game and sharper users who track closing line value and hunt arbitrage. It is US-focused and mobile-first (installable as an app), with an active community on X.

  3. Who are some of the biggest customers of The Odds Gap?

    One flag here: The Odds Gap is a free consumer tool, so it has no named enterprise customers, and I didn't want to invent any. If you want to fill the field honestly, I'd list user groups rather than company names:

    • Individual US sports bettors, the core users
    • Betting-focused Discord communities that license the odds bot for their servers
    • Sports content creators and cappers who embed the free odds widget
  4. What's the story behind The Odds Gap?

    The Odds Gap was built by a solo founder in Michigan who got tired of paying -110 at his sportsbook for bets an exchange was quietly pricing better, and realized almost nobody line shops because checking 19 books and 4 exchanges by hand is miserable. So he built the thing that checks, with every exchange fee baked in and the best price flagged automatically. It has grown into a full free toolkit, built in public, on one principle: math, not picks. The site never tells you what to bet, only where the same bet pays more.

  5. Which are the primary technologies used for building The Odds Gap?

    A Python (Flask) backend with a SQLite datastore, deployed on Railway with continuous deploys from GitHub. The front end is server-rendered HTML with vanilla JavaScript, shipped as an installable PWA with push notifications. Live odds come from The Odds API plus direct exchange APIs (Kalshi, Polymarket, ProphetX, and Novig). Supporting pieces include a Python Discord bot, transactional email, Google Analytics 4, and a Capacitor-based iOS build.

  6. What makes The Odds Gap unique?

    The Odds Gap is a free line-shopping tool that treats sportsbooks and prediction-market exchanges as one market. It compares live prices across 19 sportsbooks and 4 exchanges (Kalshi, Polymarket, ProphetX, and Novig) on every moneyline, spread, total, and player prop, and flags the best number with each exchange's trading fee already baked into the price you see, so you are comparing what you would actually get rather than a raw quote. It is math, not picks: no touts and no premium tips, just where the same bet pays the most, backed by a full toolkit (hedge finder, arbitrage and middle scanners, DFS grading, a bet tracker with automatic closing line value, a profit-boost wallet, and 11 calculators). The comparison board is free forever with no account.
