Vuniva · Visual app builder

Build apps visually. Own the code.

Vuniva — build apps visually, own the code. Design your app and get a real React Native project delivered to your own repository. No AI in the code generation, pushed to your GitHub or GitLab as a pull request, iOS, Android and web from one design. Free 1 app, Solo €19/mo 3 apps, Studio €49/mo 15 apps.

React Native · Expo SDK 57+  ·  ~40 files, standard structure, no proprietary runtime

No AI in the code generation

The same design produces the same output, every time. An assistant helps you build — the code itself comes from a compiler.

Your repository, not ours

Pushes to your own GitHub or GitLab as a reviewable pull request. Stop using it tomorrow and the app keeps working.

Sign-in that already works

Email, Google, Apple or Facebook — with Supabase, Firebase, Clerk, Auth0, or hosted by Vuniva.

Row-level security, generated

Mark an entity as owned-by-user and the policy comes with it — enforced by the database, not by the client.

Mobile and web from one design

The same app runs on iOS, Android and in the browser. Not a wrapper — the same components, rendered natively.

Multilingual from day one

Every label is a translation key. Add a language and a switcher appears, with the choice remembered.

Never charged per end user — your app's data lives in your own Supabase or Firebase account. Prices as of September 2026, VAT excluded.
