How to use it

  1. 01

    Import schema source

    Paste or open bounded SQL DDL or DBML and choose the intended database dialect.

  2. 02

    Design and inspect relationships

    Browse editable tables and fields, search a scalable ER canvas, and review primary keys, foreign keys and structural diagnostics.

  3. 03

    Compare and export

    Save or paste a baseline, classify schema evolution risk, and export interoperable source, diagram, dictionary and evidence formats.

Frequently asked questions

Does it connect to a database?

No. It parses schema text and never requests credentials or opens a database connection.

Which SQL dialects are supported?

Common CREATE TABLE syntax for PostgreSQL, MySQL, SQLite and SQL Server is supported; vendor-specific procedures and every ALTER form are outside the bounded parser.

Is the ER layout editable?

The diagram is searchable and scalable, while structural edits happen in the table editor and regenerate the source.

Does a breaking label guarantee migration failure?

No. It is a deterministic review classification for removals, type changes and stricter nullability; validate production data and migration tooling separately.
