SpacetimeDB Reviews — Discover what people think of this product.

SpacetimeDB is a high‑performance real‑time backend framework and database designed for interactive applications and multiplayer games. It embeds your server logic directly into the database, enabling memory-speed execution, automatic client synchronization, and dramatically simplified infrastructure. Instead of orchestrating microservices, queues, and custom APIs, you work in a single cohesive backend that scales to millions of transactions per second.

With SpacetimeDB, you write reducers and server logic in TypeScript, C#, C++, or Rust, while the framework handles persistence, deployment, and stateful real‑time updates. Clients subscribe to data changes and receive updates instantly, making it ideal for chat systems, collaborative editors, and MMO‑style experiences.

Key capabilities include:

• Embedded server logic for ultra‑low latency and strong type safety
• Automatic client sync for real‑time state updates across browsers and devices
• High‑throughput transaction engine benchmarked against popular databases
• Language flexibility across modern ecosystems (TS, C#, C++, Rust)

Teams use SpacetimeDB to ship complex real‑time experiences faster, from Discord‑like chat clones to full MMORPG backends, all without managing traditional infrastructure.
