SpacetimeDB – A database that replaces your server

In plain words

SpacetimeDB is a database that lets developers upload application logic as WebAssembly stored procedures, eliminating the need for a separate web server. Clients connect directly to the database, which handles authentication and authorization. The makers built the game BitCraft entirely with this architecture, storing and syncing all game state directly through the database. SpacetimeDB is available on GitHub under the BSL 1.1 license, which converts to a free software license after several years. It's designed for developers building real-time applications that require direct client-database communication.

In the maker’s words, at launch

We just released our database, SpacetimeDB, on GitHub under the BSL 1.1 license. It converts to a free software license after a few years. The point of the database is that you upload application logic into the database as a WebAssembly stored procedure, so instead of clients connecting to a webserver they connect…

  TeaTime – distributed book library powered by SQLite, IPFS and GitHub2024 · github.com · ▲307

  Recently there seem to be a surge in SQLite related projects. TeaTime is riding that wave... A couple of years ago I was intrigued by phiresky's post[0] about querying SQLite over HTTP. It made me think that if anyone can publish a database using GitHub Pages, I could probably build a frontend in which users can decide which database to query. TeaTime is like that - when you first visit it, you'll need to choose your database. Everyone can create additional databases[1]. TeaTime then queries it, and fetches files using an IPFS gateway (I'm looking into using Helia so that users are also…

  DriftDB – an open source WebSocket backend for real-time apps2023 · driftdb.com · ▲367

  Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  LLMs can generate valid JSON 100% of the time▲854

  Outlines is a Python library that focuses on text generation with large language models. Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works. Our original background is probabilistic, relational and symbolic programming. Recently we came up with a fast way to generate text that matches a regex (https://blog.normalcomputing.ai/posts/2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…
