Mathesar – open-source collaborative UI for Postgres databases

In plain words

Mathesar is an open-source tool that provides a spreadsheet-like interface for working with PostgreSQL databases. It allows users to connect to existing databases or create new ones, with UI elements like links mapping directly to database features such as foreign keys. The tool is designed for anyone needing to access and manage relational data without writing SQL, and is maintained by a non-profit organization.

  Hosted version of Mathesar, intuitive open source UI built on PostgresJun 2026 · mathesar.cloud · ▲6

  Hi HN! We just shipped the public beta of the hosted version of Mathesar, our open source “intuitive spreadsheet UI, full PostgreSQL power” project. Until now, using Mathesar meant installing and running it yourself. Now you can use Mathesar for free without having to maintain your own infrastructure at https://mathesar.cloud. Mathesar Cloud is run by the Mathesar maintainers through the 501(c)(3) nonprofit that already maintains the open source project. We’re committed to ALWAYS keeping Mathesar 100% open source (no open core), nonprofit, and treat self-hosting as a first-class…

  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…

  BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT▲688

  I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
