Its strength lies in its AI-powered optimization of email and SMS alerts, combined with on-site elements like popups and badges. The app targets merchants primarily concerned with inventory management and maximizing sales through effective restock notifications, particularly those using Online Store 2.0. Hulk Form Builder, on the other hand, is a versatile form creation tool. It enables merchants to build a wide range of forms, from contact and registration forms to surveys and wholesale order forms. Hulk Form Builder empowers merchants to collect various types of information from customers, enhancing customer engagement and streamlining business processes.

While ES Back in Stock concentrates on automated notifications driven by inventory status, Hulk Form Builder prioritizes data collection and customization through flexible form design. The higher review count of Hulk Form Builder suggests broader adoption across Shopify merchants, possibly due to the more universally applicable need for custom forms compared to niche inventory notifications.
