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 directly to the database. The database itself does authentication and you write your own authorization logic just like you would inside a webserver. We’ve developed our game, BitCraft (https://bitcraftonline.com) entirely in this way. All of the game state is stored and…

Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…

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…

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…
