Open protocol for per-user storage on the Web
Webfinger + OAuth + CORS + REST


For users

Own your data

Everything in one place – your place. Use a storage account with a provider you trust, or set up your own storage server. Move house whenever you want. It’s your data.

Stay in sync

remoteStorage-enabled apps automatically sync your data across all of your devices, from desktop to tablet to smartphone, and maybe even your TV or VR headset.

Compatibility & choice

Use the same data across different apps. Create a to-do list in one app, and track the time on your tasks in another one. Say goodbye to app-specific data silos.

Go offline

Most remoteStorage-enabled apps come with first-class offline support. Use your apps offline on the go, and automatically sync when you’re back online.

For developers

Backend as a Service

Develop your web app without worrying about hosting or even developing the backend for it: your users will connect their own backend at runtime.

Infinite Scalability

No matter if 5 hundred or 5 million users are using your app, your backend scales automatically and never costs you a single cent.

Wheels Included

remoteStorage.js is a JavaScript library that does all the heavy-lifting of connecting to any remoteStorage backend, caching, synchronizing and storing user data.

Browse apps Get storage

Developer library

The remoteStorage.js library does most of the heavy lifting to add offline storage and cross-device synchronization to your apps. No more worrying about accounts, databases, passwords…


const rs = new RemoteStorage();
rs.access.claim('todos', 'rw');

const client = rs.scope('/todos/');

Write an object

// Declare an object type to validate if you want (JSON Schema)
client.declareType('todo-item', {});

// Write `{"id":"alfa","done":false}` to /todos/alfa.json
await client.storeObject('todo-item', 'alfa.json', {
  id: 'alfa',
  done: false,

Get objects

const specificItem = await client.getObject('alpha.json');
const allTodoItems = await client.getAll();

Add the Connect Widget UI component

Use our drop-in UI widget for connecting remote storage accounts.

const widget = new Widget(rs);
