Fairplay Bet is owned and operated by Fairplay Exchange Limited. There are no sister sites, unless you count the exchange section of the brand, so we have listed some alternatives below.

Fairplay Bet is the spin-off version, or the addition if you like, to the already popular Fairplay Exchange. The latter was launched in 2023 and is a way for mates to bet against each other, with everything from sports bets to social bets. The fixed-odds addition is no surprise, though, as it helps Fairplay offer the complete package.
Given how unique the original product is, there are no sister sites unless you count the exchange side of the site. While some might see that as a bummer, it also means that the owner Fairplay Exchange Limited only focuses on one brand (usually very good!). There is no shortage of good fixed-odds alternatives either, as seen above.
Fairplay Bet doesn't have any sister sites (excluding Fairplay Exchange), so we have picked out three sites below that we think operate in the same realm.
BestOdds is another new site in the UK, launching in 2025 just like Fairplay Bet. The site uses the Playbook Gaming platform, which we have been a fan of for quite some time. We would even say that it's nicer than what Fairplay is using, though this could easily come down to personal preference as well.
The sportsbook depth is impressive, with racing and football receiving extra love, and there is also a casino for punters to try out. On top of that, there are some good promotions to make use of, while the overall design makes the browsing experience very nice. Like its sisters, it's a very solid brand.

SBK feels like a 'natural' choice here of sorts as it also stems from a betting exchange, more specifically Smarkets. Indeed, the latter's popularity led to the launch of the fixed-odds site and now, both of them are big in the UK. We would argue SBK still doesn't get the love it deserves from punters, though.
The betting margins are absolutely outstanding, coming in at the lowest average in the UK, and this only highlights its background with exchange betting. Furthermore, the bookie has a very good app and generous promotions, which means it has everything you would want. Except for casino, but that applies to Fairplay Bet too.

Swifty Sports might not be the first site that comes to mind when you think about 'good betting sites', but only because there are so many to choose from. Indeed, Swifty has gone a bit under the radar despite being around for several years, and it's not because the product is bad or anything.
We actually quite like the design of the sportsbook, which is very reminiscent of the aforementioned Playbook Gaming, and the market depth appears to be pretty good. There is no bet builder, however, which some will see as a huge drawback. The bookie is perhaps more suitable for horse racing as a result.
