PKVault is a local and decentralized Pkmn storage system designed to manage, back up, and transfer Pkmn data across your own devices.
It works as your personal Pkmn vault, entirely under your control — no cloud dependencies, no online authentication.
The system connects directly to your game saves (via compatible homebrew clients) and your local database, allowing full synchronization between your devices.
- Local NoSQL database for Pkmn storage.
- Express.js API for communication between devices.
- Homebrew support for consoles (e.g. 3DS, Switch).
- Web and mobile clients for management and visualization.
- Fully offline — your data never leaves your network.
- Backend: Node.js + Express.js
- Database: MongoDB (Community Edition)
- Web/Desktop and Mobile Clients: React / React Native
- Homebrew Clients: C/C++ or C# depending on platform
-
