ChartDB

Project23K

Import database schema JSON to visualize and edit diagrams, then export SQL.

What you can build

  • Write a tool that accepts two schema JSON snapshots, preserves both inputs, and reports added, removed, or changed tables and relationships for review.
  • Process imported schema relationships with custom ordering logic and produce proposed table migration batches plus warnings for dependency cycles.
  • Match fields in imported schema JSON against user-authored classification terms and output a reviewable inventory of columns that may contain sensitive data.
  • Combine imported schema JSON with a user-maintained glossary and generate a Markdown dictionary linking tables and fields to business definitions.
  • Check SQL DDL exported from ChartDB against user-authored naming or type rules and report violations with the affected statements.

Try this prompt

Build a small end-to-end schema snapshot comparison tool. Accept two schema JSON snapshots obtained from ChartDB, preserve both originals, and compare tables and relationships using custom code. Output a Markdown report of additions, removals, and changes for human review. Include sample inputs, tests for missing or renamed objects, and clear handling for structures the parser cannot compare. Do not claim ChartDB has a built-in diff feature or invent an integration API.

Get started

  1. Choose a run option

    Use the hosted app or follow the README's local setup guidance, which uses npm. Local deployment requires hosting resources you provide.

  2. Import a schema

    Choose a supported database, run ChartDB's provided smart query in that database, and paste the resulting JSON into the editor.

  3. Configure optional AI export

    For AI-assisted SQL export, configure either an OpenAI API key or a custom inference endpoint and model, as described in the README.

License & notes

AGPL-3.0ChartDB is licensed under AGPL-3.0. If you convey modified copies, AGPL conditions apply, including providing corresponding source. If users interact remotely with your modified version—including internal users—you must offer those users the corresponding source. Private use without conveying generally does not require publishing modifications. Self-hosting uses your own hosting resources. Optional AI features need an OpenAI API key or a configured inference endpoint and model; provider and hosting charges may apply. No dollar amounts are stated.

  • The documented import runs a query in the database and pastes its JSON result into ChartDB; the README does not document live database connections or an import API.
  • The README describes the project as being in public beta; verify current behavior and database support before relying on it.
  • AI-assisted SQL export requires an OpenAI API key or a configured inference endpoint and model; provider charges may apply.
