Every arbitrage scanner finds prices that cover both sides of a market. The good ones flag books you can actually reach and leave you time to get the second leg down. BetBurger has the broadest coverage, OddsJam reads prediction markets alongside sportsbooks, RebelBetting bundles value betting, Bet Hero buys near-elite coverage for less, and ProfitDuel and SureBet are niche picks.
| Tool | Best For | Coverage | Live Arbs | Entry Price |
|---|---|---|---|---|
BetBurger | International and high-volume arbers | 600+ feeds, about 160 brands | Separate plan | €79.99/mo prematch |
OddsJam | U.S. setups spanning books and prediction markets | 150+ advertised, 104+ on Platinum | Separate tier | $79.99/mo promo arb |
RebelBetting | Beginners who also want value betting | 100+ bookmakers | No | $99/mo Starter |
Bet Hero | Broad coverage at a lower price | 400+ books, 190+ countries | Pro only | €99.99/mo Plus |
ProfitDuel | Promo and +EV bettors adding arbitrage | U.S. plus Canada | Prematch-focused | $99.99/mo Elite |
SureBet (surebet.com) | Testing arbitrage on a budget | 400+ bookmakers | Prematch-focused | Free; €29.90/mo Basic |
Prices checked September 2026. We ignored advertised profit figures, which depend on your bankroll and execution, not the software.
Read the coverage numbers carefully. BetBurger's directory shows about 160 distinct brands behind its 600-plus feeds, the rest regional clones. What matters is overlap with your funded accounts: hold eight, and another 300 books you can't reach add nothing.
Then decide on live, which dies faster because prices move with the game and which pregame bettors never use. Finally, the arithmetic: $10,000 of monthly volume at a 1% edge returns about $100, which a $100 subscription absorbs entirely.
BetBurger is the pick if you hold accounts across a large international network. Prematch scans 600-plus feeds across 40 sports and 27 esports at €79.99 a month; Live is €279.99, both €319.99. With four or five accounts, most of that database never comes into play.
Pros
Cons
OddsJam is the only tool here that reads sportsbooks and prediction markets in one feed, covering Novig, Kalshi, Polymarket and ProphetX. Its own guidance shows how fast the bar rises: prematch wants three books and about $2,000, live wants six books, $5,000 and a couple of hours a day. Promo Arbitrage is $79.99 a month, Pre-Match $199.99, Live $250 then $499.99.
Pros
Cons
RebelBetting suits anyone who wants arbitrage and value betting on one bill: $99 a month for sure bets, value bets, 100-plus bookmakers, tracking and automatic settlement, with a 14-day trial that doesn't ask for a card. The workflow is deliberately narrower than BetBurger's, which keeps a beginner from watching every market at once. Pro at $209 adds sharp books and brokers, hard to justify unless you already trade there.
Pros
Cons
Bet Hero advertises 400-plus sportsbooks across 190-plus countries, far closer to BetBurger than its price suggests. Plus is €99.99 a month, Pro €199.99, undercutting BetBurger's €279.99 live tier by about 29%. Check the currency: Bet Hero prices in euros, converts on page load and defaults to the annual rate, so the first number you see sits roughly 40% under the monthly cost.
It launched in 2023, against BetBurger in 2014 and RebelBetting in 2009, so use the $1 trial to see how the feeds actually perform.
Pros
Cons
ProfitDuel is a toolkit rather than an arb terminal, covering the U.S. across 30-plus states plus a separate Canadian site. Elite bundles the Arb Matcher with an EV Matcher, Low Holds Matcher, Odds Screener and promo tools for $99.99. That is unconvincing if you only want an arb scanner, since RebelBetting Starter costs the same and focuses harder, but it earns its place for bettors who don't arb full time.
Pros
Cons
SureBet lets you see what an arb scanner looks like before paying for one. The free plan shows arbs up to a 1% threshold; Basic at €29.90 and Max at €59.90 open the rest, with Max adding exchange-commission handling and deeper odds history. It is the right shape for anyone still deciding whether the day-to-day of arbing suits them, and most active users outgrow it.
Pros
Cons
| Question | OddsJam | RebelBetting | BetBurger |
|---|---|---|---|
Books scanned | 150+ advertised, 104+ on Platinum | 100+ bookmakers | 600+ feeds, about 160 brands |
Prediction markets | Novig, Kalshi, Polymarket, ProphetX | No | Not a focus |
Live arbs | Separate live product | Not on Starter | Separate Live plan at €279.99 |
Entry price | $79.99/mo Promo arb | $99/mo Starter | €79.99/mo Prematch |
They aren't competing for the same buyer. Book count separates BetBurger, venue type separates OddsJam, scope per dollar separates RebelBetting.
A displayed profit percentage assumes both legs fill at the listed prices. The second line moves, a book cuts your stake, or two markets that look identical settle differently. That should drive what you buy: direct links cut the time between finding and placing, filters keep unusable books out, and odds-age data kills stale opportunities. The fastest scanner doesn't win by default; the one that removes friction from the accounts you already hold does.
Arbitrage software was built around sportsbook price differences. Adding prediction markets changes three things.
| Venue | Model | Pregame Straight Cost | Best For |
|---|---|---|---|
Novig | Peer-to-peer sports prediction market | No maker or taker trading fee | Sports traders who want the cheapest pregame leg |
Kalshi | CFTC-regulated event-contract exchange | Transaction fees, highest near 50¢ | Deep order books across the widest range of events |
Polymarket | CFTC-regulated prediction market | Taker fee, maker rebate | International and niche sports coverage |
We go deeper on those mechanics in our prediction market arbitrage guide.
BetBurger for high-volume users who can reach the operators behind its 600-plus feeds. OddsJam for U.S. bettors moving between sportsbooks and prediction markets. RebelBetting for a simpler bridge into value betting, Bet Hero for coverage at a lower price, ProfitDuel when arbitrage is one part of a promo and +EV routine, SureBet to experiment first.
List the accounts you can actually use, check them against the supported books, decide whether you need live, and work out the volume it takes to cover the subscription. Those checks beat the headline bookmaker count.
What is the best arbitrage betting software?
BetBurger, for high-volume and international arbers, at 600+ feeds across about 160 brands. For a U.S. setup, OddsJam, because it scans prediction markets alongside sportsbooks.
Is there free arbitrage betting software?
SureBet's free tier shows arbs up to 1%. BetBurger has a free version with delayed results. Enough to learn the workflow, not to run it.
How much does arbitrage betting software cost?
From about $80 to $500 a month. Entry tiers cluster between $80 and $100. Full live access runs €319.99 on BetBurger and $499.99 on OddsJam.
Do I need live arbitrage scanning?
Only if you bet in-play. Live feeds are the most expensive part of every product here, so pregame bettors should buy the prematch plan.
Arbitrage runs on disagreement between markets, so another independently priced source widens the search. Novig's peer-to-peer market prices off other participants rather than a house line. Check the latest markets when you compare across your accounts.
