    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…

    Hi HN, We're Rishabh, Aashish, and Noah, the creators of ProtoType: a platform for building GraphQL backends. You can check it out here: https://www.useprototype.com We were fed up with creating the same sort of APIs over and over again when building web applications so we built this tool for ourselves. As we're all in university, we showed it around to our friends and they enjoyed using it to kickstart their projects. After that, we thought we'd host it on a website and allow anybody to use it! ProtoType is different from similar GraphQL backend builders such as 8base in that it…

    For a while now I had the urge to learn how to pick the "right" database for projects, I looked around online at different databases to try to understand their different traits, and was bombarded with marketing instead of actual info on the advantages and drawbacks. The only solution for me was to learn some database internals (I read the wonderful book written by Alex Petrov), and the problems seemed so interesting, I could not fight the urge and went ahead with trying to write my own db. Anyway, ~9 months have passed and I feel like I'm "done", I have learned a ton, and really proud of…

    Last year we launched ChartDB OSS (https://news.ycombinator.com/item?id=44972238) - an open-source tool that generates ER diagrams from your database (via query/sql/dbml) without needing direct DB access. Now we’re launching the ChartDB Agent. It helps you design databases from scratch or make schema changes with natural language. You can: - Generate schemas by simply describing them in plain English - Brainstorm new tables, columns, and relationships with AI - Iterate visually in a diagram (ERD) - Deterministically export SQL script Try it out here -…

    Hi, I was a corporate lawyer for many years working with a lot of financial services and insurance companies. In practicing law, I noticed there was a lot of repetition in the tasks I was working on even as a highly paid attorney that could be automated. I wanted to solve the problem of dealing with a lot information and data in a practical way, using AI. This motivated me to start AI Bloks/LLMWare with my husband, who had a deep background in software and is a very early adopter of AI. We have been on this journey with our open source project LLMWare for the past 4 months, producing a…
