SpacetimeDB is a reactive, serverless backend platform that combines a relational database, authentication, real‑time sync and deployment in a single system. It lets developers write server logic directly in the database and automatically syncs data to clients.

Use cases

• build a real‑time multiplayer game backend with automatic state sync
• create a collaborative web app where all clients see live updates instantly
• develop a full‑stack application without separate ORM, cache or WebSocket layer
• prototype a chat or social platform with server‑side logic embedded in the DB
• run serverless functions that need ACID transactions and low‑latency data access

When to choose

• you need ultra‑low latency real‑time data synchronization across many clients
• you want to eliminate the glue between database, auth, and server logic
• your project benefits from a single type system shared between client and server
• you are building a game or high‑frequency collaborative app that requires ACID guarantees

When to avoid

• you require a mature ecosystem of third‑party extensions for a specific RDBMS
• your workload depends heavily on complex SQL analytics not yet supported
• you need fine‑grained control over underlying storage engines or custom sharding
• regulatory compliance demands a certified, on‑premise database solution
