Open-source database diagram editor with AI-generated ER diagrams
Paste a single read-only query result and ChartDB renders the whole schema as an ER diagram, with no direct database access or local agent required.
Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL.
Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation.
On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift.
Sketch Docker Compose stacks as diagrams and turn them into working YAML
Represent services and their relationships as a diagram so the shape of a multi-container stack is readable without parsing YAML line by line.
Start from predefined setups including WordPress with MySQL, React with Express and MySQL, Nginx with PHP and MySQL, and an Elasticsearch stack with Kibana, Logstash, and APM.
Begin with an empty diagram when your architecture does not match any template and assemble the services yourself.
See how containers, databases, and supporting components fit together before you run them, which helps catch missing links early.
