💬 +33 7 53 80 15 96
What do I get when I buy KeepBerry?

The complete source code of four projects: the Flutter mobile app for iOS and Android, the Flutter desktop app for Windows and macOS (which also runs on the web), the Flutter admin panel, and the Node.js backend with real-time messaging, calling and push notifications. Full documentation and a setup guide are included.

Is it a one-time payment or a subscription?

A one-time payment. There is no subscription and no per-user fee. Plans start at $799 for the complete source code.

Can I rebrand it with my own name and logo?

Yes. You receive the full source code, so you can change the app name, icon, colours and domain. On the Studio plan and above, we do the rebranding for you.

Can I try KeepBerry before I buy?

Yes. Open the web app in your browser, install the Android demo build on a phone, or sign in to the admin panel, where the demo login is already filled in.

Which platforms does it run on?

iOS, Android, Windows, macOS and the web, plus a web-based admin panel. The apps share one Flutter codebase and all connect to the same backend.

Does it include voice and video calls?

Yes. One-to-one voice and video calls use LiveKit, with full-screen incoming-call screens, call history and push notifications that wake the phone for incoming calls.

What do I need to host it?

Your own server and domain. A server of about $12 per month is enough to start. Third-party services such as push notifications, calling, storage and hosting are set up in your own accounts and paid by you.

Will you install it for me?

Every plan includes installation: we set up and configure your server, including the voice and video call server.

How many apps can I launch with one licence?

Standard allows one product, Studio allows three, and Business, Scale and Enterprise allow unlimited products with resale and white-label rights.

Which languages does the app support?

English, French and Chinese are included and switch instantly. The translation structure is shared by every app, so you can add more languages.
