Vaultrice

Vaultrice is a real-time, globally distributed key-value store with a localStorage-style API — no backend required.
Built on Cloudflare Durable Objects, it lets you sync state instantly across devices, users, and regions, with strong per-object consistency and optional end-to-end encryption.

Use it for:

• Collaborative apps & Simple Multiplayer games

• Presence tracking (“who’s online”)

• Cross-domain or cross-device state sharing

• Live dashboards, feature flags, and more

Two ways to use it:

1. NonLocalStorage — Low-level, localStorage-like API with reads, writes, events, and presence.

2. SyncObject — High-level reactive object that auto-syncs state, presence, and events.

Ship real-time features in minutes, not days — without touching WebSockets, servers, or databases.
