   InstantDB – A Modern Firebase▲1,145

   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…

   DriftDB – an open source WebSocket backend for real-time apps▲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…

   Datagridxl2.js – Fast Excel-like data table library▲301

   I'm Robbert, the creator of DataGridXL.js. Last month I released version 2 which includes many new features. DataGridXL is a free (and commercial) editable data table library written in ES6.

You don’t need any framework to use DataGridXL. - It is lightweight (~250kb) and easy to use. It does not even require messing with CSS. - It has its own Virtual DOM implementation to prevent DOM errors. - Developer friendly. Supports all modern web browsers Please take a look at…

    GoatDB – A lightweight, offline-first, realtime NoDB for Deno and React▲90

    Hey HN, We've been experimenting with a real-time, version-controlled NoDB for Deno & React called GoatDB. The idea is to remove backend complexity while keeping apps fast, offline-resilient, and easy to self-host. Runs on the client – No backend required, incremental queries keep things efficient. Self-hosted & lightweight – Deploy a single executable, no server stack needed. Offline-first & resilient – Clients work independently & can restore state after server outages. Edge-native & fast – Real-time sync happens locally with minimal overhead. Why We Built It: We needed something that’s…
