ChartDB
Browser-based database diagram editor that visualizes your schema with a single query
Overview
ChartDB is an open-source, browser-based database diagram tool that imports your existing schema with a single SQL query and renders it as an interactive entity-relationship diagram. It supports PostgreSQL, MySQL, SQLite, Microsoft SQL Server, and MariaDB. Diagrams can be edited visually, exported as images or SQL DDL, and shared. It runs entirely in the browser with no backend required, or can be self-hosted as a Docker container for team use.
Where it falls short of Airtable
- Diagramming and visualization only; no data editing, querying, or CRUD interface
- No team collaboration features (comments, live multiplayer editing) in self-hosted version
- No support for NoSQL or non-relational database schemas
- No migration generation or schema diffing workflow tools
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
