Avoid GammaStack if you value your time.
Delivery quality fell materially short of commitments, and the final product did not meet baseline requirements for a production-grade iGaming platform.
Based on this experience, we would not engage them again and cannot recommend them to operators.

Not worth the amount that you paid them. First they promised you everything and made contract as you wished. Then they gave you incomplete website and asked for extra which are very expensive even for adding simple ones. Then after getting paid, they don't care about the contract. Milestones that are included in the contract? They don't care. They will drag the project and write the codes that will have high aws cost. If you are going to work with them, please have a proper contract and follow the contract milestone only and paid them only if the milestone is done completely.Do not trust their words and pay them without any completion.
Could not agree more with what has been shared below. Timelines missed, cost increased at every turn, code not communicating with API, wallets not set up correctly, bonus engine was set to turnover not loses, I could go on for days!!!Cost us in the hundreds of thousands and still working through 6 months after site was delivered.
We hired GammaStack for two major projects worth over $250,000 - a casino platform and a set of seven original games. Unfortunately, what we received was buggy, inconsistent code, with major parts missing or nonfunctional. After nine months of delays and minimal progress, we had to rebuild the entire codebase ourselves in order to launch. Although we had paid in full for the games, several of them did not work as promised. When we raised these concerns, we were told further work would require an additional $49,000 - more than double the outstanding balance. This was despite already having paid for broken or incomplete code. They wouldn't even have a call with us to ask questions so we could fix it ourselves. Our experience with GammaStack was extremely disappointing. We hope other startups avoid the same mistake.
I have been alongside Gammastack for some time now. They are not producing any SEO friendly development and all of the code is failing Pagespeedinsights and lighthouse testing. They refuse to fix these issues.They are a nightmare to communicate with, and promise the world but deliver peanuts. We are really not happy with these guys,
