{"slug": "spacetimedb", "title": "SpaceTimeDB", "summary": "SpacetimeDB launched as a reactive backend platform that bundles database, server logic, auth, deployment, and real-time sync into a single system, pitching itself to AI coding agents with the claim that LLMs \"go much further\" on it because there is no glue code or extra services to wire up. The company says server logic runs directly inside the database in Rust, C#, or TypeScript with strongly serializable ACID transactions, delivering \"100x-1000x better performance\" than conventional databases, and cites BitCraft's real-time multiplayer backend as a production user. Developers quoted in the material describe building a multiplayer flight simulator in one hour and shipping a game to the App Store before Halloween with 95% of a three-month development cycle spent on the front-end client.", "body_md": "Spacetime is a reactive backend platform that AI agents love: database, server logic, auth, deployment, and real-time sync in one place. [LLMs go much further](/llm-benchmarks) with Spacetime because there's no glue to wire up, no extra services to misconfigure, and one type system across your client, server, and database. Your agent gets it right the first time.\n\n`curl -sSf https://install.spacetimedb.com | sh`` spacetime dev --template chat-react-ts``claude \"This folder is initialized with a basic Spacetime project. Using this as a starting point build a full Discord clone with channels, threads, and real time messaging with React.js\"`\nSpacetime automatically publishes updates to your clients so they're always in sync. Your server code is embedded into the database to give you extreme flexibility and type safety.\n\nNo web server, ORM, cache, networking, or sync layer to stand up. Spacetime is all of it, so your agent has one thing to build against instead of a dozen.\n\nSpacetime processes transactions at a scale and speed that leaves conventional databases behind.\n\nYour entire application state lives in tables.\n\nPersisted by default, including the full history of every row.\n\nSubscribed data stays synced to your clients automatically.\n\nEvery reducer is atomic. It fully completes, or it does not run.\n\nReal code running inside the database, in Rust, C#, or TypeScript.\n\nSpacetime is a general purpose relational database with strongly serializable __ACID__ transactions, that takes stored procedures to the next level. You get to deploy your server logic directly into the database for 100x-1000x better performance and a dead-simple developer experience, so whatever your agent builds is correct, not subtly broken.\n\nWhat people building with Spacetime are saying.\n\nOk, Spacetime is actually pretty cool! It gives you almost everything you need on the server side to build a multiplayer game. Think of it as Supabase but for building games.\n\nYou can write reducers to handle events on the server, and you can call them directly from the client or subscribe to their changes.\n\nSpacetime collapses your entire backend into the database itself. No servers, no microservices, just Rust modules running at memory speed. Powers an entire MMORPG with zero traditional infrastructure.\n\nSpacetime is a cheat code.\n\nThe design of Spacetime—or rather, its underlying mechanism—is so genius that I just can't stop grinning like an idiot, oh my.\n\nIf you don't know yet, Spacetime is here and it's going to warp the game dev space into a new big bang.\n\nThink of it as whatever levelsio had to vibe code for his plane game to be a smooth multiplayer game, you can do it in an hour now.\n\nSpacetime — a database and server in one. Clients connect directly, run logic inside the DB. No Docker, no K8s, no ops bloat.\n\nUsed to power the entire backend of BitCraft, including real-time multiplayer.\n\nIt's time! I'm using Spacetime to backend my game, Vaerfel idle. It's an original idle mmorpg. We're almost at a point to where I'm comfortable asking for fundraising money for professional hooman-made art assets, etc.. Let me know what you think!\n\nI did develop and operate a successful web3 marketplace with the full stack.. kubernetes, postgres, elastic search, risingwave, redis etc... imho for game dev go with @spacetime_db. Currently building an @PlayArtifact clone in godot and spacetimedb and its fun and painless\n\nUnironically you can achieve this with a single rocket API and spacetimedb behind a loadbalancer.\n\nWe started concepting the game in July, and shipped it to the App Store before Halloween. 95% of the 3 month development time was spent developing the front-end client.\n\nThe backend was completely plug-and-play. It's genuinely shocking how easy Spacetime made it to create a persistent open world.\n\nI couldn't resist! Heard about Spacetime yesterday and had to vibe code a flight simulator. One hour in, it's completely multiplayer with a Rust + Spacetime backend.\n\nlove you spacetimedb ❤️\n\nFor anyone who ever wanted to play with multiplayer try this platform out, its really amazing.\n\nwe've been looking at it since launch, one of our developers loves you guys so much", "url": "https://wpnews.pro/news/spacetimedb", "canonical_source": "https://spacetimedb.com", "published_at": "2026-09-14 14:06:38+00:00", "updated_at": "2026-09-14 14:18:36.808866+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "ai-infrastructure", "developer-tools", "ai-products"], "entities": ["SpacetimeDB", "BitCraft", "Rust", "C#", "TypeScript", "React.js", "Godot", "App Store"], "alternates": {"html": "https://wpnews.pro/news/spacetimedb", "markdown": "https://wpnews.pro/news/spacetimedb.md", "text": "https://wpnews.pro/news/spacetimedb.txt", "jsonld": "https://wpnews.pro/news/spacetimedb.jsonld"}}
