Great app with great customer service! I use this app extensively for some very complicated products and it works better than anything else we have tried. If there is ever a problem, customer service is very quick to help solve it. Thank you!

We were long-time users of Bold Product Options and later SC Product Options. When we were notified that SC Product Options was being discontinued, we were encouraged to migrate to Keystone Product Options. The migration process was extremely frustrating. SC Product Options worked perfectly with our highly customized Shopify theme, but Keystone initially did not. We spent a significant amount of time with our own developers and the Keystone support team trying to resolve compatibility issues. To their credit, Keystone Support was very responsive and worked diligently to help troubleshoot and fix the issues. After considerable effort from both sides, the app does now appear to be functioning properly. However, the biggest frustration came later when Keystone acknowledged that SC Product Options was actually not being discontinued. This made the original communication encouraging customers to migrate very misleading. We invested a substantial amount of unnecessary development time and resources moving away from an app that was already working perfectly for our business. Ultimately, it felt like we were fixing something that was never broken. We are an established ecommerce company doing over $10 million in annual sales with a heavily customized Shopify storefront. For stores like ours, changing a core product options app is not a simple plug-and-play process. The initial troubleshooting advice often centered around testing Keystone on Shopify’s default Dawn theme, which may be useful for diagnostics, but it does not reflect the reality of many larger stores running custom themes. Keystone Product Options may be a great solution for newer stores, simpler themes, or merchants starting from scratch. However, if you operate a larger Shopify store with a customized theme and already have a working product options solution, I would strongly recommend carefully evaluating whether migration is truly necessary before committing the development resources. The Keystone team deserves credit for their support and persistence, but the migration recommendation created a lot of unnecessary work for our business.

I'm reverting back to SCPO since this app does not support listing the product options separately at checkout. If can only bulk up the price of the existing product.

We are long time Bold, then SC Product Options app users (by this same company). When I was concerned about the migration to this, their new app, they gave me the white-glove-treatment. They took care of each detail and worked out any issue very quickly. Their support is quick and very capable. Since this kind of app is crucial to our store, I'm thankful for such a stellar team behind the app. Thanks Ahmed Piric and team for always being there when I need you!

Was not as easy to install as the Migration Guide indicated. Several steps were not as described, and then I found out I had a Shopify 1.0 Theme. I tried following the instructions for Legacy themes. Installing the Keystone code was ok, but there were no instructions about removing the SC Product Options code, which I had been using. I basically had to give up on my old Theme that I really liked and had a great deal of personalization on and switch to a new Shopify 2.0 Theme, so that I could add the "app block" into the theme. So, it took over 2 hours instead of 10 minutes and I am still not done. I have the core of my store up and running (I hope), but have a lot of fine tuning left to do. Update - 6/26/26 Their support team did reach out to me afterwards and offered to help with removing the old code. I had already switched over to the new theme and had decided to keep it since it was a more up to date theme and easier to use. However, another issue came up with certain payment options not functioning well with the app and they offered to help get that sorted out. That saved me a bit of time since I am not overly familiar with coding and that end of things.

I had the old product builder for 10 years plus. It was always a bit glitchy, how ever I only used it for 1 items and the newer app was cost prohibitive. Especially with how much effort had to go into the previous builder. However this one has been a dream, so easy that in the 3 days I have had it, I have built 4 other items for the website, it's not glitchy and is very user friendly. Hightly recommend.

The Keystone team helped me set up my custom pet portrait store perfectly. The file upload feature works flawlessly and the support was outstanding. Highly recommend!

Very responsive and they work fast to get you what you want and need from their product.
