You can test a startup idea with a real app: claim the template closest to the idea (most are free), put your colour on it and your name with any plan, prepare an install for a small group of testers, and reshape it in plain English as the feedback comes in. The whole loop costs a plan at $5 a month and a few credits per change.
What a working app can help you test
A clickable design can help test whether people understand the idea. A working app lets them try saving data and returning later. Choose the smallest useful behaviour to observe, such as making and changing a booking. Reusing a template avoids creating every screen from scratch; it does not prove demand or remove the need for testing.
How to build an MVP without a developer
- Pick the template nearest the idea. A marketplace, a members club, a booking app, a social feed: the bones are usually already there.
- Claim it free, choose its colours, and add your name with any plan. Try the preview and follow the installation steps, with its managed starter backend.
- Ask for the two changes that make it yours in the app’s chat. Each is a few credits.
- Send the Android install link to your first users. The link serves the latest build; testers still need to install each new version you ask them to test.
- Watch what they do, then ask for the next change.
What it costs
Standard templates are free every time; premium ones cost credits to claim. The Basic plan is $5 a month with 50 credits, and a simple change uses some of them. Direct Android installation is subject to device permissions and developer verification. iPhone testers need the app signed through an Apple developer account, which is $99 a year and has to be yours.
Where it stops
Be honest with yourself about what this is: a finished template reshaped around your idea, not a bespoke platform. Anything that needs heavy media processing, background jobs or text messages is not something to promise in week one. The backend starts on a managed project with a storage cap. Production or store builds, integration secrets, and growth beyond the starter limits require your own Supabase project. If the idea works, you can download the code, publish to the stores under your own developer accounts, and keep going with a developer who starts from something real instead of a whiteboard.
