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.
Run many coding agents in parallel, each in its own worktree
Each agent gets its own isolated Git worktree, so multiple agents can edit, test and build concurrently without conflicts.
Works with Claude Code, Codex, Gemini, Cursor CLI, OpenCode, Copilot, Cline and many other command-line agents using subscriptions you already have.
A built-in browser lets you click any element to copy its HTML, styles and selector, or screenshot a page and drop that context straight into an agent prompt.
Review AI output, run commands and arrange terminals, browsers, files and diffs in panes shaped to the task at hand.
