## What it is
remoteStorage.js is a JavaScript/TypeScript client library for storing user data locally in the browser and syncing it with remoteStorage servers, as well as optionally Dropbox or Google Drive accounts. It enables offline-first, unhosted apps where users connect their own storage account, so developers need no backend for user data.

## Use cases
- add offline-first data storage and sync to a web app
- let users connect their own storage account instead of building a backend
- sync app data across devices and applications
- cache data locally with localStorage/IndexedDB and sync when back online
- integrate Dropbox or Google Drive as user storage in a JavaScript app
- build unhosted apps that keep working when the server is down
- share data between apps via open data modules

## When to choose
- you want offline-capable apps with automatic sync and no server-side user data storage
- you want users to keep control of their data by connecting their own remoteStorage, Dropbox, or Google Drive account
- you need a mature, production-tested client-side sync library for browser or Node.js apps

## When to avoid
- you need a traditional hosted backend with server-side business logic over user data
- your app requires relational queries or complex server-side data processing
- you only need simple key-value storage without cross-device sync
