How to build an MVP or app prototype without coding?

Prototype or MVP: what can you build?

With vibe coding the line between a mock-up and a real product gets thin. You can build:

• a clickable prototype to show the main flow of your idea, screen by screen, in a meeting or a user interview;
• an MVP (minimum viable product) with sign up, login, user roles and data saved in a real database, ready for your first testers;
• a web app or a mobile app: choose the type of project at the start, and mobile apps are shown inside an iPhone or Android frame.

Typical examples: a platform that connects parents and private tutors, a booking tool for a coworking space, a community app for runners, a niche tool for a specific profession.

Start in Plan mode

Before building, use Plan mode. Here the agent reasons with you without touching any files, which makes it a good sparring partner to:

• decide the one problem your MVP must solve and the one flow to test;
• list the types of users (for example customers, providers, admin) and what each one can do;
• define the data: profiles, requests, bookings, reviews;
• cut what is not essential for the first test.

When the plan is clear, switch to Build and the agent turns it into a working app.

Step by step: from plan to working prototype

1. Describe the product. Users, main flow, data and the look you want. The agent may ask one or two clarifying questions with options to choose from.
2. Watch it being built. The live preview appears next to the chat. The agent creates the database tables and the login on its own when the project needs them.
3. Fill it with sample data. Ask the agent to add realistic example content, so the demo feels alive.
4. Refine the flow. Point at any element of the preview to change it, or attach a sketch or a screenshot of an app you like.
5. Let the agent handle errors. Build errors are fixed automatically, and browser errors are sent to the agent with one click.
6. Share it privately. Your MVP has a private preview address, such as https://yourname.previewmyvibe.com, that only you and the people you give permission can open: perfect for testers and investor meetings.

An example request for an MVP, and why it works

The example request on this page describes a real product in two sentences. It works because it names:

• the two sides of the platform (tutors and parents) and what each one does;
• the core flow: create a profile, search, send a request;
• the data: subjects, rate, availability, city;
• the roles: an admin who approves new tutors;
• the demo needs: realistic sample data.

Notice what is missing: chat, reviews, maps. Those can come later, once you know people actually want the core.

Showing it to users and investors

• Give access to testers: once you give them permission to open the preview, they can sign up and use the MVP from any browser.
• Open it on a phone during a meeting: ask the agent for a QR code pointing to your app.
• Collect real data: sign-ups and requests are saved in tables you can inspect in the Backend tab.
• Show your progress: every change creates a version with a changelog, a nice way to show how the product evolved after each round of feedback.
• Iterate fast: change a screen in the afternoon and test it again the same evening. If an experiment goes wrong, restore an earlier version.

From MVP to real product

An MVP built this way is not a throwaway mock-up. It is a real project: a React and TypeScript frontend, an admin panel, a PHP API and a MySQL database. You can download the full source code as a ZIP at any time, also for free, with Docker files included, and sync it with GitHub, GitLab or Bitbucket so every version becomes a commit.

That means that when your idea is validated, a developer or a technical co-founder can pick up the project from where you left it, instead of starting from zero. When you want to open it to everyone, put the code on the hosting you choose; one-click hosting is coming soon. Meanwhile, you can keep improving it yourself with the agent or in the built-in code editor, the same one used in VS Code.
