1000x faster than your database - SpacetimeDB.

Submitted May 26, 2026

Session type - select the format for your session: 30-minute talk – technical deep dive

Description:

Modern realtime systems are full of accidental complexity. APIs talking to databases, websocket servers managing state separately, caches trying to stay coherent, synchronization code everywhere, and endless coordination between layers that were never meant to work together in realtime.

This talk looks at a different approach through SpacetimeDB — a database that combines storage, server-side logic, and realtime networking into a single runtime. I’ll walk through what changes when compute lives next to the data instead of across the network, why this model works especially well for multiplayer and collaborative systems, Benchmark numbers, and what we learned while building MMO-scale infrastructure with a very small engineering team.

Takeaways:

  • A different way to think about backend architecture for multiplayer, collaborative, and realtime applications.

  • How colocating compute and data removes large amounts of backend coordination and synchronization complexity.

Target Audience:

Backend engineers, distributed systems engineers, multiplayer game developers, and teams building realtime or collaborative systems.
