Rork generates mobile apps from prompts. Shippen gives you a production-grade system to build and ship native apps. Both target mobile — but the approach is fundamentally different.

At a glance

Feature	Rork	Shippen
Approach	Prompt-to-app generation	Boilerplate + AI agents
Output quality	Prototype / demo-grade	Production-grade
Code ownership	Limited export	Full, from day one
Backend	Basic / generated	NestJS + Supabase (pre-wired)
App Store deployment	Manual	Automated scripts
Customization	Prompt-limited	Full code access
Stack	Expo (generated)	React Native + Expo (structured)
AI integration	Single generation step	11 agents + 13 skills

Breaking it down

1. Generation vs engineering

Rork's promise is compelling: describe your app, get a working mobile app. And it delivers — to a point. You get a functional prototype that looks good in a demo. The problem starts when you try to turn that prototype into a real product.

Generated code is hard to maintain. The architecture decisions were made by AI in a single pass — no planning, no structure, no consideration for how the app will evolve. When you need to add a feature that doesn't fit the generated pattern, you're fighting the codebase.

Shippen starts from the other end. The boilerplate is human-designed, production-tested architecture. AI coding agents work within that structure to help you build features. The code is readable, maintainable, and designed to grow.

2. The last mile problem

Getting a mobile app from "looks good in a demo" to "live in the App Store" is where most AI app builders fail. You need:

• Proper signing certificates and provisioning profiles
• App Store metadata, screenshots, and descriptions
• Privacy policy compliance
• Push notification configuration
• In-app purchase setup (if applicable)
• Backend that scales beyond demo traffic

Rork gets you the demo. Shippen includes automation for the entire App Store submission pipeline — the boring, critical work that actually gets your app into users' hands. See the step-by-step submission guide.

3. Backend reality

Rork generates basic backend functionality as part of the app. But generated backends are notoriously fragile — no auth strategy, no migration system, no type safety, no security policies.

Shippen ships with a NestJS backend pre-wired to Supabase. Row Level Security, typed API layer, auth flows, file storage, push notifications — all configured and tested. You're not debugging generated backend code; you're building on a foundation.

The full stack includes Stripe payment integration and EAS Build for automated deployments. See the Expo + Supabase + Stripe stack for the complete picture.

4. Iteration and maintenance

The first version of any app is the easy part. What matters is: can you iterate? Can you fix bugs? Can you add features without breaking existing ones?

With Rork, each major change often means re-generating or manually patching generated code. The AI doesn't have context of your custom changes.

With Shippen, the 11 AI agents understand the codebase structure. They plan features, implement them within the architecture, and handle deployment. You're iterating on a real product, not re-rolling a prototype.

5. Where Rork wins

For rapid prototyping and idea validation, Rork is genuinely fast. If you want to see what an app could look like before committing to building it, Rork gives you that in minutes. It's also more accessible to non-developers — no local setup, no terminal, no React Native knowledge needed.

If your goal is a demo for investors or a quick proof of concept, Rork delivers that faster than setting up any development environment.

Verdict

Use Rork if:

• You want to validate an app idea quickly with a visual prototype
• You're a non-developer exploring what's possible
• You need a demo, not a product
• Speed of first version matters more than long-term maintainability

Use Shippen if:

• You want a production-grade app in the App Store
• You plan to maintain and iterate on the app long-term
• You need a real backend with auth, security, and scalability
• You want full code ownership and control
• You're building a business, not just a prototype
