Before picking a vibe coding platform, ask five questions: does it generate a real backend or just a frontend; do you own the exportable code; what happens to your app if you stop paying; how is authentication actually handled; and can it deploy to real users rather than just a demo? The answers separate platforms that can carry a real product from those that can carry a demo. As of 2025–26, the vibe coding category has clearly split between frontend-only and full-stack platforms, so these questions have real, checkable answers. That wasn't true two years ago.

Most founders don't ask these questions before signing up. They find out the answers later, when it's most expensive to find them.

Why do most people ask the wrong questions first?

The questions founders usually ask are: how fast can I build something, what does the UI look like, and is there a free tier? Reasonable questions. Also, the questions a platform's marketing page is optimised to answer well.

The questions that determine whether your product survives contact with real users are different. They're about architecture, ownership, and what happens when the product needs to do something the platform didn't anticipate. Marketing pages are not optimised to answer these clearly. Some platforms actively obscure them.

I've watched non-technical founders commit months of work to a platform and discover — when they had users, when momentum was real, when switching costs were the highest — that the foundation wasn't what they thought it was. The five questions below are the ones that would have told them earlier. None require technical knowledge to ask. Some require persistence to get a straight answer.

Question one: Does this generate a real backend or just a frontend?

This is the question that splits the category.

A frontend is what a user sees and clicks: screens, buttons, forms. A backend is what happens when they click: the database that stores their data, the logic that processes it, and the auth system that keeps one user's data separate from another's. A product needs both.

Some platforms generate the frontend and wire it to a third-party-managed backend service. The frontend looks complete. The backend exists, technically, but you don't control it, can't extend it beyond what the managed service exposes, and can't move it without rebuilding. Other platforms generate the full stack as code you own: frontend, database schema, auth layer, API endpoints, all of it in your repo.

When I evaluated Mayson for my own projects, this was the first question I asked, specifically because I'd already seen what the alternative looked like. On an earlier project, I used a frontend-first platform — the UI came together fast, looked production-ready, and then I needed a background job for async processing. The managed backend layer didn't support it cleanly. Three evenings trying to work around the platform's constraints before accepting the architecture wasn't going to hold. That project stalled.

Ask the platform directly: "Is the backend generated as code I own, or is it a managed service?" If the answer involves a third-party service name without elaboration, follow up: "Can I access and modify the backend code directly, outside your platform?" That follow-up is where you find out what you're actually buying.

Question two: do I own the code, or am I renting the app?

Related to the first question but distinct. A platform can generate a real backend and still not hand you the code. What matters is whether the generated code can be exported to a repo you control and whether it remains functional if you leave the platform.

There are positions platforms take on this that you need to distinguish between. The one that actually matters: you own the code, it lives in your repo, the platform is a generator, not a host. You can take the code, work with it directly, extend it with a developer, or move it to a different infrastructure. Leaving the platform doesn't break the product. Everything else is a variation of lock-in, ranging from partial to complete.

Ask: "If I cancel my subscription, what happens to my application code? Can I export it and run it independently?" Read the terms of service on data portability and code ownership. The platforms that answer this question clearly and confidently are the ones with nothing to hide about the answer.

Question three: what happens to my data and my app if I stop paying?

Different from code ownership. This is about operational continuity — what keeps running and what doesn't when the billing stops.

If you stop paying, scenarios range from your app keeping running on your own infrastructure (you own the code, you deployed it yourself) to the app going offline, and the data isn't easily recoverable. Most platforms sit somewhere in between. What matters is where exactly and whether that matches your risk tolerance. A side project with no real users has different continuity requirements than a product with paying customers.

Ask: "If my subscription lapses, does my application continue running? What's the grace period? Where is my data stored, and can I export it at any point?" A platform without a clear, documented answer to this question is giving you an answer by omission.

Question four: How is authentication actually handled?

Auth is the system that lets users sign in and keeps their data separate from each other. It sounds like a technical detail. It isn't. It determines whether your product can legally and safely handle real users.

Bad auth implementation means users can see each other's data. Password resets that don't work. Sessions that don't expire. A security failure that ends the product before it has a chance.

The questions here aren't about which auth library the platform uses. They're about what gets generated by default and what you'd need to add later. Does every project come with sign-up, sign-in, and session management? Is each user's data scoped to their account by default, or does that require additional configuration?

These are harder to verify from a marketing page than the other questions. The fastest check: build a small test project on the free tier, create two test user accounts, and see whether account B can access account A's data. Twenty minutes and you have an actual answer.

Question five: can this actually deploy to real users, or just demo well?

Some platforms are optimised for the demo. The preview looks polished. Sharing a preview link is frictionless. Deploying to a real domain with a real database that real users can sign up for is a different process, and that's where some platforms get complicated.

The questions: does the platform deploy to infrastructure you control, or does it host the app on platform-owned infrastructure? What are the rate limits, concurrency limits, or usage caps on the deployed version? If the platform's infrastructure has a problem, does your product have one too?

Platform-hosted apps aren't inherently wrong. But the dependency is real, and you should know you're accepting it.

Ask: "Where does my deployed app actually run? Can I deploy to my own cloud account? What are the infrastructure limits on the deployed version?" The answers tell you whether you're building a product or a demo that happens to have a URL.

How to use these five answers to make the actual decision

The five questions produce a decision based on what you're actually building, not on which platform has the best landing page.

A weekend experiment with no real users? Code ownership and deployment constraints matter less. Use the free tier, move fast, and find out if the idea has any traction.

A product you're charging money for, with real user data, that you expect to run for more than six months? All five answers matter. A platform whose answers you can't clearly verify is not the right platform, regardless of how fast its UI generation is.

One honest caveat: some platforms' backend architecture isn't documented anywhere easily found. You may need to test rather than read — spin up a free project, check what gets generated, find where the backend lives. Understanding what a real backend actually includes and whether you get the code or get locked in before you evaluate any platform will make that investigation faster. The platforms that make it easy to check are the ones worth trusting with something real.
