our call
Start with Shogun — highest vibe code, weakest moat.
Rebuy
You can easily build a custom slide-out cart and a basic Shopify Checkout UI Extension using modern AI coding agents in a weekend. However, duplicating Rebuy's cross-app integrations, ML recommendation graphs, and cross-channel merchandising flows requires significant long-term maintenance.

- Basic merchandise cross-sell and upsell widgets on product and cart pages

- Built-in ML product recommendation engine trained on millions of store orders
- Native deep integrations with subscription platforms like Recharge and Stay AI
- Rebuy Monetize revenue share network on thank-you pages
- Smart Search and smart collections engine

Shogun
You can easily spin up a drag-and-drop visual page editor using open-source libraries like Craft.js or GrapesJS in a few days. However, reliably compiling that visual tree into clean Shopify Liquid code, managing cross-store content syncs, and running flicker-free server-side A/B tests requires serious engineering effort.

- Drag-and-drop visual page builder canvas.
- Pre-built e-commerce layout templates and blocks.
- Basic A/B testing and split-path page routing.
- Mobile-responsive viewport previews and CSS overrides.
- Scheduled page publishing and draft states.
