I haven't checked all of the scripts on that website, but the one you were looking to buy
[archived link] is called "
Betify" and apparently it was made by "Royal Design Studio
[archive of their website - archive of their dribbble page]" but for some reason, all of their pages are gone
[except for their Telegram (you could try asking for a demo in there, but I prefer not to vouch)]... It's worth noting that the seller in question, took multiple screenshots from the video link that I shared earlier
[refer to the Betify part] and changed its name to "BET" instead!
There's really no script to check all the seller has are screenshots and descriptions of the casino platforms that he claims to own, if you check all the other marketplaces they provide a working demo to satisfy their potential clients, you don't buy a car based on the description you have to ride with it first and check all the features if everything is all there, if they don't want the demo posted in public at least they can do this in private conversation but they don't have these in their offer.
The guy could be a bogus seller so buy with extreme cautions.
intersting how you find it. dribble is a site to find web designers not developers.
beitify is a design only they use only fronted html, css, jquiry, figma to make it not complete backened casino (lareval , php etc=
the designer you sent here is very talented they also made another casino
https://dribbble.com/shots/18760107-CryptoBet-Casinobut she is only web designer and fronter developer.
to make a complete casinos is a whole different story and has huge costs there is a lot of backened work that need to be done. months of works.
like i said this guy most likely just photoshop the design from there and try to sell it as he has backened code.
