Show HN: ChartDB Agent – Cursor for DB schema design
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.
Now we’re launching the ChartDB Agent.
It helps you design databases from scratch or make schema changes with natural language.
You can:
- Generate schemas by simply describing them in plain English
- Brainstorm new tables, columns, and relationships with AI
- Iterate visually in a diagram (ERD)
- Deterministically export SQL script
Try it out here - https://chartdb.io/ai - no signup required.
Or sign up and use it on your own database
Would love to get your feedback :)
