Local first. Your app reads and writes to a local database. Users get instant responses, even without a connection. When they're back online, Sp00ky resolves changes and syncs state across every device — no loading spinners, no conflict modals, no extra code on your end.

Fig 0.1

Rust Core

Memory-safe. No runtime overhead. Just raw performance.

Fig 0.2

Instant UI

WASM powered optimistic updates. Every interaction feels immediate.

Fig 0.3

Job Scheduler

Retries, backoff, and outbox — your background work just runs.

Fig 0.4

Fast Realtime

Sub-50ms propagation. Changes arrive before you notice the delay.

How It Works

It feels like magic

Direct state synchronization powered by SurrealDB

SurrealDB native sync engine

Sp00ky bypasses traditional REST APIs in favor of direct state synchronization on top of SurrealDB. Built for modern real-time applications that need instant updates across all clients.

Authentication-agnostic security

Integrate with any identity provider while maintaining fine-grained access control. SurrealDB's flexible security model adapts to your authentication strategy.
