SpacetimeDB is a relational database with embedded server-side logic (reducers), real-time client sync, auth, and deployment built into a single Rust-based platform. It replaces the traditional stack of web server, ORM, cache, WebSocket layer, and database with one type-safe system for building multiplayer games and realtime web apps.

Use cases

  • build an MMO or multiplayer game server without separate backend services
  • create a realtime chat or Discord-like app with live sync
  • replace PostgreSQL + Redis + WebSocket server with one system
  • write server logic as stored procedures in Rust, TypeScript, or C#
  • sync client state automatically with database subscriptions
  • self-host an ACID transactional database with a CLI
  • let AI agents generate a full backend with no glue code

When to choose

  • you are building a multiplayer game or realtime app and want database, server logic, and sync in one platform
  • you want type safety across client, server, and database with auto-generated bindings
  • you need high transaction throughput without managing separate infrastructure

When to avoid

  • you need full SQL features like foreign key constraints or complex joins
  • you require a permissive open-source license (it is BSL 1.1, source-available)
  • your project is a traditional CRUD app better served by PostgreSQL and a standard web framework
