Hi everyone! 👋

We’re excited to share the latest updates to ChartDB, our self-hosted, open-source tool for visualizing and designing database diagrams - built as a free and flexible alternative to tools like dbdiagram.io, DrawSQL, and DBeaver's diagram feature.

Why ChartDB?

✅ Self-hosted – Full control, deployable anywhere via Docker
✅ Open-source – Actively developed and maintained by the community
✅ No AI/API required – Deterministic SQL export with no external dependencies
✅ Modern & Fast – Built with React + Monaco Editor, optimized for performance
✅ Multi-DB support – PostgreSQL, MySQL, MSSQL, SQLite, ClickHouse, and now Cloudflare D1

Latest Updates (v1.8.0 → v1.10.0)

🆕 Cloudflare D1 Support Import schemas via Wrangler CLI
🆕 Deterministic DDL Export Replaced AI-based export with native SQL generation
🆕 Sidebar for Diagram Objects Quickly navigate tables, fields, indexes, and FKs
🆕 Better Canvas UX Right-click to create FKs, table drag-and-drop, better visibility controls
🆕 Internationalization Added full French & Ukrainian support

What’s Next

Git integration for diagram versioning

This is really cool and I will definitely try it out! Am I missing something or is there really no contributors license agreement?
Any way of having this study an existing database (or dump thereof) and build the graph? I have an oracle database that nobody understands, built by someone else, and I thought something like this could help..
- I've never used the tool, but I'm guessing that your Oracle database can create an SQL dump of its schema which presumably is how this tool ingests a database to chart.
Deterministic DDL Export - Replaced AI-based export with native SQL generation
Much better. Now it works for my case, which it didn't before.
- Awesome, glad to hear it's working for you now! 🎉 We realized native SQL generation was the right move for reliability and consistency. Appreciate you sticking with it - let us know if you run into anything else!
Nice db visualization, will try it out
I gave it a quick look, it's neat. I will definitely be using it for future/existing projects.
Saving this one for later
This looks really cool. Anyone know if there is a way to make something like this ingest a gedcom file and put out a visual like this?
