About SpacetimeDB
SpacetimeDB is a combined relational database and server that lets clients connect directly to the database and execute application logic inside it. It’s built for developers building real-time multiplayer apps who want low latency and minimal ops by running logic inside the database instead of a separate game or web server.
Key Features
In practice, you publish modules that compile to WebAssembly and run inside the database, while clients call into the same surface to drive game state and logic. This approach reduces latency and simplifies deployment for multiplayer workloads:
In-database deployment
deploy and run your app logic as SpacetimeDB modules that compile to WebAssembly and execute inside the database.
Direct client access
clients connect directly to the database and run logic without an intermediary server.
Module-driven primitives
use tables and reducers to model state and orchestrate actions inside the database.
Operational minimalism
avoids Docker, Kubernetes, VMs, and extensive ops infrastructure.
Summary
Best for real-time multiplayer game teams, backend engineers building low-latency services, and startups looking to reduce ops overhead.
