Low Latency
Global Edge Network
Real-time Sync
NonLocalStorage API
import { NonLocalStorage } from '@vaultrice/sdk';
const nls = new NonLocalStorage(credentials, 'shared-object-id');
// Set a value from one client...
await nls.setItem('hello', 'world from client A');
// ...and listen for it on another.
nls.on('setItem', 'hello', (item) => {
console.log(item.value); // 'world from client A'
});How It Works
Go from idea to live, collaborative app in minutes. Our architecture is designed to make real-time simple and scalable.
Your Serverless Real-Time Backend
When we say Vaultrice lets you build real-time apps with "no backend," we mean there is no backend for you to build, manage, or scale.
Your application's architecture with Vaultrice is simple, powerful, and built on world-class infrastructure. We handle the complexity of real-time data synchronization, global distribution, and WebSocket management so you can focus on building great user experiences.
🌐 Global Edge Network: Built on Cloudflare's infrastructure for low-latency access worldwide
1. Define Your State
Use the simple setItem() API that feels just like localStorage. Store strings, numbers, or complex JSON objects with ease.
2. Sync Instantly
Any change to your data is instantly broadcast over a persistent WebSocket connection to all subscribed clients. No polling, no manual refresh.
3. Collaborate Everywhere
State is seamlessly synced across all tabs, devices, and even different domains, making it perfect for building unified user experiences.

If you know localStorage, you know Vaultrice. Get up and running in minutes with a simple, intuitive API that doesn't get in your way. Live data sync and a full Presence API are included. No need to integrate or pay for a separate WebSocket provider. From default transport encryption (TLS) to optional client-side End-to-End Encryption, you choose the level of security your data needs.
What Will You Build?
Vaultrice is flexible, but it's purpose-built to solve common developer challenges.
Cross-Domain User State
Share user preferences, session state, or a shopping cart across multiple domains or subdomains.
NonLocalStorage API
// On site-a.com
await userPrefs.setItem('theme', 'dark');
// On site-b.com, the change is instant
userPrefs.on('setItem', 'theme', (item) => {
// item.value is 'dark'
});Collaborative Applications
Build real-time features like "who's online" lists, shared to-do apps, or simple multiplayer game lobbies with our integrated Presence API.
NonLocalStorage API
// See who's currently viewing the document
await nls.join({ name: 'Alice' });
nls.on('presence:join', (conn) => {
// console.log(`${conn.data.name} is now online.`);
});
const connections = await nls.getJoinedConnections();
console.log(`${connections.length} users online`);
connections.forEach(user => {
console.log(`${user.data.name} joined at ${new Date(user.joinedAt)}`);
});Real-Time Feature Flags
Enable or disable application features instantly for all users without deploying new code.
NonLocalStorage API
// In your admin panel
await featureFlags.setItem('enableNewDashboard', true);
// In your client app
if (await featureFlags.getItem('enableNewDashboard')) {
// show new dashboard
