ChartDB
Database visualizer.
What we like
Generates schema visualizations without needing to connect to the DB. Supports major DBMS e.g. ClickHouse, MySQL, PostgreSQL, SQLite. Make edits and export the results. Save and share diagrams (cloud version). You can also self-host.
What we don't like
Requires running a several-hundred line script to import the existing structure, which is fine so long as you check what the script is doing.
