SnapQL – Desktop app to query Postgres with AI▲104
SnapQL is an open-source desktop app (built with Electron) that lets you query your Postgres database using natural language. It’s schema-aware, so you don’t need to copy-paste your schema or write complex SQL by hand. Everything runs locally — your OpenAI API key, your data, and your queries — so it's secure and private. Just connect your DB, describe what you want, and SnapQL writes and runs the SQL for you.

DB Pro – A Modern Desktop Client for Postgres, MySQL, SQLite and LibSQL▲33
Hi HN, Over the past few months I've been building DB Pro with my co-founder. DB Pro is a modern desktop database GUI client designed to make working with Postgres, MySQL, SQLite, libSQL and other engines feel fast, visual, and enjoyable. Our focus has been on the dev-experience. We wanted to absolutely nail the UX and look and feel as we believe most db clients aren't friendly to work with. Some features: Visual change review – See pending inserts/updates/deletes before committing them. Inline data editing – Edit table rows directly without clunky modal dialogs. Raw SQL editor – A…

PostgreSQL course with database running in your browser▲6
I wanted to brush up my SQL skills and was looking for an online course that included a live DB. Most PostgreSQL courses require you to create an account or pay. This is probably because they have to bear the costs of running a full server-side database. So I created learnpg.xyz, a collection of PostgreSQL SQL exercises that run client side. Sharing here because it might be of use to people!

OxideDB – Teach PostgreSQL Database How to Speak MongoDB Wire Protocol▲30
Hey everyone! I have created a product that relies on MongoDB for a document store but doesn't really need any of the distributed features to really justify having a hosted MongoDB or DocumentDB instance. Now that we're trying to turn this into a product, we're seeing that some companies have a little bit of resistance around managing yet another database. Most of our clients already have and manage PostgreSQL in one form or another. I knew that PostgreSQL already offered first class JSON support, but I didn't want to rewrite the application data layer from scratch if I could avoid it.…

MVP done, now what?▲5
I've spent about the past 6 months or so working on what I think of as 'database as a service'. Essentially hosted Sqlite with CORS support so users can post from anywhere, and execute queries saved on the backend. One of the things I'm going for is a completely in browser development experience, so there's nothing to install, the user simply uses the UI to create and edit queries and admin their database. One of the most basic uses would be posting form data from a static HTML page: https://www.lite-engine.com/blog/post_form.html I've posted it here before and didn't get…

I built a database for AI agents▲12
Hey HN, I just spent the last few weeks building a database for agents. Over the last year I built PostHog AI, the company's business analyst agent, where we experimented on giving raw SQL access to PostHog databases vs. exposing tools/MCPs. Needless to say, SQL wins. I left PostHog 3 weeks ago to work on side-projects. I wanted to experiment more with SQL+agents. I built an MVP exposing business data through DuckDB + annotated schemas, and ran a benchmark with 11 LLMs (from Kimi 2.5 to Claude Opus 4.6) answering business questions with either 1) per-source MCP access (e.g. one Stripe…
