Full-stack BaaS

From sign-up to sync,
one platform.

Simply gives your product auth, teams, real-time object sync, and file storage — all from a single API key. The SDK handles the client side so your UI stays simple.

One hook. Live data, offline ready.

The Simply SDK gives React apps a real-time, local-first data layer in a single hook. No extra infrastructure, no websocket plumbing.

// Drop-in React hook — live object sync
const { objects, create, update } = useChainStore('my-app');

await create('post-1', { title: 'Hello world', published: false });
await update('post-1', { published: true });

// Works offline. Flushes as one sync on reconnect.

Everything your app needs, nothing it doesn't

🔐

Auth

User sign-up, login, and API-key management out of the box. RS256 JWT tokens, multi-tenant app isolation.

👥

Groups

Role-based group membership — build teams, orgs, or multiplayer rooms with one API call.

📦

Sync

Local-first data with automatic conflict-free sync. The SDK handles offline storage, queuing, and reconnect.

📁

Files

S3-backed file storage with group-scoped access control and pre-signed URLs. No extra config.
