@TheOddsGap
The Odds Gap shows you which sportsbook or prediction market is paying the most for the same bet. It is free, it gives no picks, and it never tells anyone what to bet. Your picks stay yours; we show where each one pays the most.
A line-shopping site. We collect the price of the same bet from 10 US sportsbooks and 4 prediction markets and exchanges (Kalshi, Polymarket US, ProphetX and Novig) and put them side by side, best price first.
Every board opens free with no signup. Add your email and the Live Beta gives you faster prices, in-game odds, the full finding tools and alerts, still free. For you and your members, the only paid product is historical odds data for people building models.
Math, not picks. We never grade your plays, never tell anyone what to bet, and never promise anyone income. Our +EV list compares prices with the market's fair line; it is not a pick.
Game lines, player props, futures and live games. Prediction-market prices are the price you could actually fill at $100 with fees included, not the top of the screen.
Nothing matches that. Try another word, or tap All.
Where every price lives. All free to open, all ranked best to worst.
Moneyline, spread and total for every game, with every book side by side and the best price flagged. Filter by day, sport and the books you can actually bet at, search any team, and tap a price to add it to the bet slip, which finds the book paying the most for it.
Turn on the LIVE pill in the Line Shop and you see in-play moneyline, spread and total across the books while games are running, with the score beside them. It is part of the free Live Beta: add your email and it is on.
Every book's over and under price on player props, best price per line and the book that has it, with alt lines behind each row.
Ask things like "best price on the Falcons +1.5?" or "I have $50 on the Saints at +150, how much do I hedge?" (a player prop ticket too: "hedge my Josh Allen over 1.5 passing TDs at +120 for $50") and TOG Bot answers from our own prices. Every number in an answer is checked against the data before it is shown. It is on the website for Live Beta members, and in Discord as /odds ask, 10 questions per person per day.
Every book that posts a futures market, side by side, with the best price on each team or player. Save the ones you follow and filter to them.
Every game has its own page: every book's price on each market, the opening line, and a chart of how the line moved that you can drag to read any moment. The page stays up after the game with the final score, so a link you post never goes dead.
Every game of the week ranked by how far apart the best and worst book are. There is one for college football, the NFL, the NHL, the NBA, college basketball and MLB.
Free research, built from the same prices. For the NFL, college football, the NBA, college basketball, the NHL and MLB.
Team trends download free as CSV or JSON, so you can work with them in a sheet.
Pick a league and the books you use, and download the week's lines as a CSV that opens in Google Sheets or Excel. Add the opening line and the consensus, the moneyline, and the odds if you want them, each in its own column. Every line is a plain number, so the sheet sorts and does math with no cleanup. Free, no sign-in.
Tools that do the math with every book's price already loaded, so nobody types odds in by hand.
Pick the bet and we find the best price on the other side across every book, then work out the stake. Seven modes:
Parlay Hedge and Futures Hedge are part of the free Live Beta.
When you hedge a bet you choose your goal, and the stake is worked out for it:
Save the profit boosts your books give you in the wallet, tap Generate, and Boost Arb checks every one against the whole board: where to bet each side, the exact stake, and what you keep either way. Boosts are saved in your browser with no account; Live Beta members can sync them across devices.
Plays where the most you can lose is small next to what you win when it hits. Every middle, prop middle and arb on the board that wins at least five times what it risks at a +EV price gets the same strip: Risk, Win, the Chance it hits (the books' own prices with the vig removed, 100% for an arb) and the multiplier. Type your stake once and every number scales to it. Filter by league, market, the most you are okay losing and the chance; sort by multiplier, chance, win or +EV %.
Log a bet and it fills in the best book and price. Bets settle from final scores, and with the Live Beta the tracker also records whether you beat the closing line, the number that says whether a bettor is getting good prices over time.
On the website, hedge alerts, bet results, middle alerts and Gap and +EV alerts come with the free Live Beta. Price watches and game reminders are in the iPhone app.
The same boards in an app: the Line Shop, props, futures, live games, the bet slip, line history, the Hedge Finder and the Bet Tracker, one tap from your home screen. Add your email for live prices, still free.
Prices inside your server. Setup takes about three minutes.
Members type /odds and get every book's price, best first. It asks for two permissions only, Send Messages and Embed Links, never reads your chat, and every link it posts goes to theoddsgap.com, never to a sportsbook.

Build a single pick or a parlay up to 8 legs and get an image with every book's price and the best one highlighted. Add your own background and label, choose which books show, then download a 1080 by 1350 PNG or copy it straight into Discord or X. Free, as many as you want.
One copy-paste script tag puts today's best prices on your blog, forum or landing page, and it updates itself. Choose the sports, the books, the market (moneyline, spread, total or all), how many games, and a light or dark look. No signup, no API key.
Send Dan your card and he builds a page on our site that prices every one of your plays at every book. Prices are pulled fresh each time the page loads, so you share one link and it never goes stale. Dan does this every week for The Coverboys, a college football show.
/odds ask switched on in your server.Dan builds and runs the site himself, so requests go straight to the person who can make them.
Every price from every scan: game lines from every book, player props at set points before the game and at the close, the de-vigged fair price on every row, and prediction-market prices with fees applied. Files come as CSV, JSON or Parquet.
The Trends data comes with it: every team's results against the closing spread and total, game by game, full player game logs with each player's season average before every game, graded player props, game conditions and every line move, each row with the same game details (home or away, rest, favorite or underdog, the opening and closing lines).
Leagues on file, each added with its first finished game: Tennis, MLB, College Football, UFC, WNBA, MLS, NHL, NFL, La Liga, Serie A, Premier League, Ligue 1, Bundesliga, Champions League, NBA, World Cup. A league with a small sample so far says so on its page, and the sample grows with every game.
You never need this to use the site or the bot.
There is also a free, read-only JSON API of the live best prices, no key and no signup, for personal and AI-assistant use with a credit to theoddsgap.com. It is not for resale or commercial use.

One email each morning: how the lines moved in last night's big game, new finds from Trends, and where the books disagree most on the weekend slate.
