ChartDB – Open-Source Database Diagrams | Self-Hosted Alternative to dbdiagram.io & DrawSQL
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
- SQL import support for PostgreSQL (via DDL script)
- AI-powered table relationship detection
- More database support and collaboration tools

We’d love your feedback, contributions, or just to hear how you’re using it. Thanks!
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.
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.
That means a lot - thank you! 🙌 Super excited to hear you'll be using it in your projects. If you ever have feedback, ideas, or run into anything, feel free to reach out!
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?
