The Best Sports Arbing Software

This article is aimed at people who have at least a basic understanding of sportsbook arbitrage. If you’re new to advantage play gambling be sure to check out this introductory article on matched betting.

I get a lot of emails asking: “Which arbing software is the best?”, or “how much should I pay for an arb finder?”.

They’re good questions, and I often deflect from giving my opinion as there really isn’t one answer that fits all. The scene is regularly changing, new software providers come and go, prices change and most importantly the bookies are always improving and varying their gubbing criterias.

To make things harder for the average arber, often the advertising on the arbing software’s own websites is incredibly spammy. Even the best, most reputable companies seem to feel it’s their duty to try and lure you in with the exaggerated promises of vast riches. How do you know which site to use when each one reminds you of fonejacker?

Over the years I have personally used a lot of different types of arbing software. But on top of that I have also have taught over 100 other arbers who have tried and errored their way through all sorts of techniques and programs. I doubt there’s a decent arb service out there that I haven’t had at least a play around with.

I will try and explain which ones I think are the best and why. But first I will examine the two biggest mistakes I see people make time after time.

What Not To Use

Free Arbing Software

This may sounds counter intuitive. Surely free is better? And you’d be right.. if your plan is to only ever place just one or two arbs.

The main problem is not that free arbing software is worse than the paid software (although they are). Rather it is that anybody can see the free arbs and anybody can bet on them. Whenever an arb appears on free arb finder, hundreds of would-be arbers bet on it. And the bookies notice.

The quickest way to get your accounts gubbed or closed down is to use a free arbing software.

Why do you think that the services are free? How do they make any money? Well the only way is through what are known as affiliate links. Basically a bookie will pay the arb finder a small fee for each customer they refer. This model only works if there are hundreds or thousands of people using the arbing software.

It’s all well and good saving on the monthly subscription fee, but is it really worth it if you’re giving up 90% of the profit by having your accounts gubbed so quickly?

That being said there are times when I do use free services. And that is if I don’t care about profiting from arbing – if I am simply taking advantage of a free bet.

Most free services (and some paid ones) are rip-offs of Oddsmonkey’s free matched betting odds comparison service called MBassist (as of 2017 you now need to sign up to access it). MBassist is great, but as the name suggests it is not meant for arbitrage. Instead, it is an odds comparison service designed to help you maximise your return from matched betting.

Really Expensive Arbing Software

So does that mean I should buy the most expensive software out there? It will surely be most exclusive and have the best functionality.

Well yes and yes. But, and it’s a big but, you can quite quickly get to a point where the amount you are spending on the software outweighs the extra exclusivity benefits.

If you’re paying a £500 a month subscription fee, it takes a lot of grunt work just to get the turnover away to break even.

By all means if you’re turning over £300,000 a month then you should be using the best. But hardly anyone turns over that amount, and if you do you probably already have some pretty good arbing software!

Plus these days the difference between the really expensive software and the affordable options really aren’t that far apart.

What To Get

For the Professional

best arbing software

RebelBetting was a new kid on the block back in 2009 and I remember exactly how excited we were. They were one of the first arb finders to offer dutches rather than just straight arbs against Betfair. A big improvement on anything that had come before.

I also remember that their first version of the software had a glitch in it that meant you could re-enter the free trial so it would keep resetting. Ahh, happy times. They eventually sent me a polite email commending us for finding the loophole and offering a discount on their monthly subscription. Fair play to them.

Since then they have gone from strength to strength and are now solidly considered one of the best. Lots of bookies, lots of sports, lots of markets.

It currently costs €129 a month, with hefty discounts if you purchase a longer contract (€69 a month if you pay for the year up-front). You can also purchase just one week for €39 if you want to try it out.

As a general guideline, if you expect to turn over £20,000 or more a month then I recommend RebelBetting.

The creme-de-la-creme of arb finders. Apart from a few really high-end services that have waiting lists, years long, this is the best.

For the Hobbyist

best arbing software

Remember how I was saying that MBAssist was a very good piece of free software for matched bettors? Well, the company that brought you MBAsist also have a premium, paid version. At only £15 a month OddsMonkey is an absolute bargain.

There are a lot less features than RebelBetting. For instance, there are no dutches, which removes 90% of the opportunities. And the arbs are all ‘simple’ arbs, which means you are likely to get gubbed quicker than a higher end service.

Update: OddsMonkey Premium now offers 2-way and 3-way dutching. Even better value.

But despite this, bang for buck, it is great value. You’re not going to get anything better for less than £50 a month and it beats looking for arbs manually.

On top of the great oddsmatcher, OddsMonkey also comes with a lot of other great features. They are especially useful if you also dabble in matched betting. There is the daily offers calendar.

When that screenshot was taken (19 April 2016), there were 16 offers with guides just for today! Totally over £200 in expected profit.

Update Feb 2017: Check out my updated Oddsmonkey review for 2017

They also have a very active forum with over 1,000 posts.

If you’re turning over less than £20,000 a month (or if you’re into matched betting and looking to increase your returns) go for OddsMonkey Premium.

Both OddsMonkey and RebelBetting accept Skrill as a payment method.

Something In-between

OddsMonkey and Rebelbetting are by far the best, but if you’re looking to spend somewhere in-between there are a few other options of arbing software.

Betonvalue has been around for a long time, and you can tell. The website looks terrible and is full of flashing lights and eye-sores. It is a very complex piece of kit with over 180 different bookies feeding it. If you’re an arbitrage geek, you’ll love it.

But personally, I think it is too complex and clunky to use. I’m only mentioning it because it is so much cheaper than Rebelbetting. If you want something professional but can’t afford to shell out for the best, Betonvalue could be for you.

There are three levels of subscription of which the ‘Expert’ is probably the only one worth it. It cost €50 a month and for that you get access to everything, including all the bookies and every type of arb. The only issue is that it comes with a three-minute delay. But when you account for the time it takes to log into the websites, deposit and check the matches, that three minute delay isn’t long enough to truly matter.

Have you tried any of these and still prefer different arbing software? Please let me know!

  • Me and my friend made our own arbing script, we started using this bookie sheet:

    • Aaron

      What language did you use to make the arbing script?

      • It was a combination of PHP, AJAX, SQL, XML.

        • Aaron

          Ah so purely online? Does the bookie sheet give you information on every single bet on the market over all 56 bookies then? Would you be willing to share your software. How much would you charge for it? Have you thought about making an automated script?

          • Our script is automated 🙂 but we are not selling or sharing.

            The sheet does not provide information about bets, it provides information about the 56 bookmakers specified on the website.

            For example this information is required when you are trying to use arbing techniques.

            A few examples of the info provided is:
            – Min Deposit and Max Deposit amounts
            – Time it takes for the deposit to become active
            – Time it takes for withdrawal to be processed
            – Deposit Limits
            – Withdrawal Limits
            – Commissions on Deposit/Withdrawal
            – Payment Services they use to process payments (like Skrill or
            other services)
            – Other limitations and tips

            These are just a few examples.
            If you want to make money arbitrage betting is the way to go.

            You can compare all 56 bookmakers to see differences between them, all this information cannot be obtained on your own unless you have the possibility to make an account on all 56 websites and constantly monitor the changes in their rules, which would need a lot of man hours and information parsing techniques.

            The sheet is not just beneficial for arbing techniques or software, it’s a good comparison table for all bookmakers, you can see by comparing them that they are not all equal, there are great differences and you might not be using the best bookie for your desired outcomes.

            For example an automated betting script requires instant deposit and withdrawal to be available and you also have to take in consideration their amounts limits, and you need to bet on multiple bookies at the same time.

          • Aaron

            Ah. Now I see. That’s very cool. How is the actual information on bets obtained? I was thinking of building something myself, or hiring somebody to build something for me. How does rebelbetting, for example, get access to all of the markets it does? As you said you would need an account with all the bookies and very advanced monitoring software. Something to check each page, pretty much at all times.

          • Parsing the data is not hard with PHP. I cannot share more with you I am sorry. But I will tell you this: You should start with buying the bookie sheet while it’s discounted, it was around 200$ when we first bought it, it’s cheaper now and then depending on demand.

            It’s pretty valuable if you ask me, I would sell it for much more, hundreds of dollars. Even if you’re not going to build arbing software, it’s useful to have.

            And I would not share it with anyone, first of all it would mean copyright infringement and secondly it’s not good to have competition in this activity, the more people do this, the more bookmakers adapt to arbing techniques and implement counter-measures.

          • Btw, do you have an email I can contact you? I might send you some tips in the future. Don’t post it here. You can message me on twitter @lucian_apetrei or facebook at

          • Aaron

            I do have an email. I’m now also fairly sure that you own that betting sheet. Haha. I will add you on facebook.

          • I am flattered but it’s not my website 😀 – but I do know the owner. And he noticed my comments lol, and told me you contacted them but your email is not valid, you probably had a typo or something.

          • Aaron

            I’ve emailed the owner again and I’ve also added you on facebook.

  • John Dwight

    Hey, I recommend finding a programmer who can do this job for you.
    I tried many times to find a good arb finder, but useless, so i decided to make one for me.
    I managed to get with 3K a guy that scraped 3 bookmakers for me with 2 sports and 10 combos. Cheap, fast. And now, he is offering support/improvements for that software.

    Recommend that u do the same.

    • I developed arbing software to monitor horse racing arbs on ~15 bookies with sub 1 second refresh rates. It cost quite a lot more than £3k! There was also quite a lot of ongoing maintenance as the bookies made changes to their site.

      I think that if you have a really specific requirements (such as really fast refresh rates or unusual sports/bookies/combinations) then you don’t have a choice but to develop your own software.

      But otherwise I really suggest using one of the ones out there. Rebel betting is very advanced – probably better than what you could build yourself, and is a lot cheaper!

  • Bibo Bibi

    Hello Guys,

    i am desperate to have a full working tool/software that automates the process of placing arbs.
    i am new to arbitrage .

    could anyone of you please who has a software or a tool send me a copy of it ?

    i have tried with rebelbetting however i could just get the trial version which offers arbs under 0.6 % .

    Please help me , you can PM privately .

    Many thanks

    • Dale Moore

      I’m actually in the progress of developing an arbitrage platform that aims to _almost_ automate the process of placing arbs. =)

      • A few people have tried the automating of placing arbs (including me). There are countless difficulties with it (such as how to bypass catpchas), but I’m sure an excellent programmer could probably solve them. The main difficulty is that it is against the t&c of most bookies and therefore they’d be within their right to void your bet if they caught you. So if you do get it working, don’t tell anyone!

        EDIT- well you could PM me cause I’d be interested, but noone else!

        • Dale Moore

          I actually do have a way around captchas, using AI and programmed neural networks, I get around 90-95% accuracy, depending on the dataset. The automation part will happen on the client’s computer and behaves exactly like a human would, so a lot of random human like variations included.

          I’ll PM you, because I’m interested in other potential issues I could face that I haven’t experienced or thought of yet.

          • Joshua

            Hey, I’m a software developer too and I’m also looking to automate arbing. I’m looking to collaborate with other developers, so get in touch if you need a partner.

  • John R Moss

    Hi Guys, I run an online betting blog and I’m currently spending a lot of my time investigating whether arbs can be done on a large scale. I already use software to make around 1-1.5k a month but just wonder if it can be increased, perhaps using exchanges only so that there’s no limitations with being banned by the bookies. Cheers.

  • northeastman999

    Hi Sam, thanks for this great post and for all your other interesting articles.

    Could you clarify one thing for me, please? You mention ‘turning over’ £20,000 a month. Do you mean £20k in total bets made? Bets or lays? Or profits? Thanks.

    • Ahh, sorry should have clarified. I mean £20,000 turnover on the back bets. It’s just a rough estimate. If you’re making 4% on turnover that’s £800.

      • northeastman999

        Brilliant, thank you.

  • Blueman

    Sam, I have been match betting for a couple of months now and lost a few accounts due to the amount of value taken out of the bookie (annoying when mug bets win). If you dutch on this level are you not simply going to get restricted very soon?

    • Yeah losing accounts to them getting ‘gubbed’ (restricted to a max bet of zero) is one of the biggest problems with arbing and dutching. Without it we’d all be multi-millionaires. It’s a bit of a game, you try and place bets that stay below the radar and sometimes place mug bets to throw them off the scent. I can’t tell you exactly how to avoid gubbing because it is always changing and you need to learn it by trial and error.

  • arberhunter

    Yeah I agree with Blueman. Bet365, in my opinion were the best all round fixed odds company. They tolerated me for 3yrs … Until I upped the stakes … Then had a bunch of winners in one month. For £390000 stakes in 2015 returned me £431000. I think they disliked that !

  • Excellent article arbing and matched betting are great ways of making money online. It is tough keeping accounts whilst arbing and there is always going to be a certain lifetime for each account. You can make enough to build a good bankroll though and reinvest in other opportunities

  • Nick Nick

    Interesting set of applications here. We are also looking into building arbitrage functionality into our sports betting platforms. . Will publish an update as soon as it becomes available.

  • Takis apple

    Hello,i am from Greece and here we have problem with the most bookmakers.The goverment have give access only to these bookmakers:
    championsbet,betshop ,magicbet,stoiximan,Starbet33,sportingbet,betrebels,Novibet,1×2-bet,Joinbet
    What do you advice me to do for arbs?

    • ΜονοΠΑΣΟΚ

      Use VPN

      • Takis apple

        Vpn is good to hide yoyr IP but if you want to make withdrawal you can not as they will ask you to give them proof of your address,utillity bill,intetidy ID and if they see that your proof address is different from your IP that they see he will keep your money.I have an example that 1xbet dont give me my gain 400 euro,i loose my money and i can not do something as the bookmaker is not acceptable to my country,so they can not help me.

        • ΜονοΠΑΣΟΚ

          There are several bookmaker and the majority of the exchanges that allow Greek players to subscribe. However if you try to do it w/o the use of a VPN service you cant even access the sites as the authorities block the page. Try to find those bookmakers that allow Greek players and are accessible via VPN an verify your account before placing any bets to avoid incidents like that you describe. Thats all the advice I can give unfortunately

    • Tasos Likhaon

      I m from Greece too. I hope to have a talk about arbing if it is possible for us because I m a beginner

      • Takis apple

        Welcome to the game Tasos!We have more problems the arbers from Greece because we have less bookies as the most bookies are in blacklist and these less that we have are not friendly.The problem is that is dangerous to bet in other bookies that is not acceptable in your country.Maybe you will have problem after to withdrawal.

    • lucas

      Hello….am kindly requesting to give me more light about arbitrage

  • You talk about dutching but don’t explain it. What is it and how does it make money?

    • it’s pretty complicated and worthy of a post all by itself! I actually did my university dissertation on it.

      Here is a good description in one of the forums I follow:

      It’s basically just the name for when you are backing all the outcomes of bet to lock in a profit. In standard arbing you back at the bookie and lay at the exchange. In dutching you back all the outcomes at different bookies. It is more complicated because there are all sorts of different combinations of bets that cover all the outcomes and the maths can be pretty hard.

      • Dale Moore

        I am a software engineer and a bit of an amature mathematician.
        Back in 2008-2009, I began working on a pet project to find arbitrage trades, after playing around with the mathematics I thought it was possible to find Arb trades using only the bookies, that covered >3 outcomes, like horse-racing. This also lead to the discovery of another trade type, because I also found that certain bet types were mathematically compatible for discovering arbs. With these new sets of algorithms I was finding trades that were unbelievable, ~20% was a daily occurrence and we only had 6 bookies programmed.

        Unfortunately this also lead to an exponential growth in memory and cpu utilization which was crashing the application, and we were also getting banned for scraping too often, so after I lost the project due to a hard-drive failure I decided to shelve the project until I had gained the skills needed to address all the issues I faced.

        About 3 months ago I realised that I now have the skills needed, so I’ve began rewriting the application, I’ve got a prototype coming soon, I’m hoping that with this I’ll be able to get some private investors and be able to show some members of the arbitrage community to get feedback. Fingers crossed!

        • Good luck. It’s worth checking that some of the bigger arb finding companies don’t already offer the arbitrage type you found. It would be a shame if you spent all that time developing the software just to discover rebel betting already offers it.

          3-way arbs. Each-way arbs. Asian handicap arbs. Over/under arbs. Where all known about in 2008/9 but noone was developing software for them. Now all the major arb finders include them.

          • Dale Moore

            Sage advice. I’m currently putting together an extensive business case to go with my prototype, these are the things that I’m currently investigating and which lead me to your website.
            But yeah, it’s not just the different arb types, or the automation, but also looking at implementing features that help reduce the risks associated with arbing.

  • Linz Gold

    I was interested in Arb Betting and thought Id give it a go. I did 2 very small bets using BetVictor and a couple of other bookies. I got banned from sports betting with BetVictor straight after these 2 bets. I dont understand how arbing is possible if thats how quick they ban you. I can’t do Pinnacle Sports because I’m in the UK. Can anyone shed some light on this?

  • Владимир Дорошев

    You have indicated rebelbetting in the example. What do you think about

    • It didn’t use to be as good. But I haven’t tried there service in a couple of years now so it may have improved a lot. I will take another look.

  • I saw so many services and I didn’t saw mentioning the fastest one … they even have a training program for beginners So I am mentioning it now and to complete the information here 🙂

  • lucas

    I would like to know more about a beginner but it confuses me alot
