Show HN: ChartDB Cloud – Visualize and Share Database Diagrams

Me and Guy (@guyb3) built ChartDB to generate ER diagrams from your database without a need of any database access (via query/sql/dbml). We started with an open-source version, and after seeing a lot of use we decided to make a cloud version.

Our OSS launch (1y ago) – https://news.ycombinator.com/item?id=41339308

Now we’re launching ChartDB Cloud – built for teams:

– Embed ERDs into docs, dev portals, or Miro/Notion etc.

– Collaborate in real-time (with live cursors like Figma)

– Keep diagrams always in sync with your database

– Organize large, messy schemas without pain

– Export DDL in multiple SQL dialects (solved deterministically)

– AI assistant to brainstorm and generate new schema objects or schema changes

We designed it so working with databases feels less like a chore and more like a creative process.

Would love feedback – especially from teams dealing with messy schemas or outdated docs.
