# Code57 > Code57 is an independent software studio that builds Shopify apps. Four apps are publicly available — Gift Card Factory, DataJet, BoomGate, and Bundle Factory — all distributed through the Shopify App Store, each with a "Built for Shopify" designation where awarded. Code57 also takes on bespoke Shopify projects. Code57 specialises in deep, well-engineered apps that integrate natively with Shopify (Shopify Functions, Cart Transform, Theme App Extensions, Polaris admin UI) rather than overlay tools that fight the platform. Support is handled by the same engineers who wrote the code. ## Apps - [Gift Card Factory](https://code57.pl/apps/gift-card-factory): Bulk gift cards, discount codes, and store credit for Shopify.
