## What it is
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
