SpacetimeDB 2.0 makes the database your game server.
You run game logic “inside” the DB, model world state as tables, and expose moves/damage/spawns as reducers. Clients (like Three.js) subscribe over WebSockets and get fine‑grained diffs instead of polling, so the server stays authoritative and the client just renders and interpolates. Generous free tier, paid starts at $25/month.

From a technological risk perspective I would never tie myself to a vendor like that. I know people do it all the time, but you are totally at the mercy of the vendor increasing price and having no choice but pay since you are so tightly integrated. Always add an interface is my moto.

I hadn't heard of SpacetimeDB but this tech looks genuinely interesting.
I'm tech lead of UGC at Rec Room and had to do similar work to support live synchronization of UGC content. We essentially built a database in our game engine (Unity) with similar capabilities.
Since it grew out of our production needs, we ended up with a lot of bespoke solutions specific to our game. I'd love to try this out and see if I could make a small UGC personal project with it or exchange notes with the people who built it.

We have been experimenting with adding Spacetime multi-player to our current threejs app. It was surprisingly easy to build the standalone demo but the full integration obviously is not as straightforward.

This looks very promising. There's a need for persisting game state in a central place, but also have that data streaming in.
I'm wondering about temporary gamestate that doesn't need to persist. Things like terrain or destructible voxels, where the size could be prohibitive to keep in a databases, but would work well in memory or with a cache.

this is pretty cool! what I do for my project (3d voxel web page platform) is treat the scene as a document and push updates to the server when things change. this works well for distribution and simplicity, but does mean multi-player is "difficult". using spacetime to manage and track that info and have threejs render would be cool and enable a lot of things.
I may explore spacetimedb as a project sometime, although i am reluctant to be tied into a platform that my project cannot work without, that i cannot host myself, that can change their pricing/limits/terms of at any time and for which there is no alternative.
