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.
Agent wiki and visual workspace for Claude Code and Codex
A plugin for Claude Code, Codex, Cowork, Cursor, VS Code or any MCP agent that turns your agents' work into editable pages covering decisions, open questions and project context.
Tasks, docs, wiki, diagrams and code share one window, so you can think and direct work without hopping between tools.
Organize agent work on a board and edit documentation or code directly in the app.
Maps how decisions, pages and questions relate so you can see the whole project at a glance.
