If you need a GUI tool that creates schema migrations automatically as you change schema - try XgeneCloud [1].

The GUI database client generates up and down SQL files automatically when you click and change schema.

Currently, it supports MySQL, MSSQL, PostgresSQL, SQLite.

Here is a simple demo how this GUI works : https://youtu.be/IKvraKy0S90
