I made an online DBER diagram editor and SQL generator

In plain words

DrawDB is an online database diagram editor and SQL generator launched in March 2024. It allows developers to visually design database schemas and automatically generate SQL code from their diagrams. The tool is designed for software developers and database architects who need to plan and document their database structures. It runs directly in the browser, making it accessible without installation.

The visual database schema tool for clear, fast, collaborative design. drawDB is, and stays, free and open source. Sponsors are what make that sustainable. Help keep it independent and moving fast. Every tier counts. drawDB speaks every major dialect — design once, then generate clean DDL for the database you actually ship on. Build diagrams with a few clicks, customize your editor, and generate clean DDL for your dialect. drawDB is fully open source.

  One year ago I open-sourced my very first 'real' project and shared it here. I was a college student in my senior year and desperately looking for a job. At the time of sharing it i couldn't even afford a domain and naively let someone buy the one i had my eyes on lol. It's been a hell of a year with this blowing up, me moving to another country, and switching 2 jobs. In a year we somehow managed to hit 26k stars, grow a 1000+ person discord community, and support 37 languages. I couldn't be more grateful for the community that helped this grow, but now i don't know what direction to take…

  ChartDB Agent – Cursor for DB schema design2025 · app.chartdb.io · ▲130

  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.

  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…
