ChartDB

Core Features

• One-click smart import: run a single SQL in your database to export the full schema as JSON, paste it in to get an instant diagram
• AI-powered DDL export: generate migration scripts in any dialect (e.g., MySQL to PostgreSQL) with AI assistance
• Interactive editing: drag-and-drop tables, add annotations, and auto-sync changes on a live diagram canvas
• Zero setup: use the cloud version or self-host via Docker; no account required
• Wide database support: PostgreSQL (+Supabase/Timescale), MySQL, SQL Server, MariaDB, SQLite, CockroachDB, ClickHouse

What It Can't Do

• •Caveats: ① AI features require an OpenAI API key or a custom inference endpoint (e.g., local vLLM) – without it, export scripts lack AI assistance. ② Privacy-focused Fathom analytics are enabled by default; disable with `-e DISABLE_ANALYTICS=true`. ③ ChartDB is currently in public beta – evaluate in non-production environments. ④ Key differentiator: unlike traditional tools (e.g., dbdiagram.io) that require manual modeling, ChartDB imports your existing schema with one query, and the AI dialect export is unique for cross-DB migrations.

Use Cases

• Document existing databases with visual ER diagrams for team reference
• Plan database migrations by previewing schema differences and generating target-dialect DDL
• Collaborate on schema design: edit tables, share link, discuss with teammates
• Reverse-engineer complex databases to understand table relationships
