There was a good stone for this: https://github.com/amatsuda/erd

But, as I see it, this was the last update 2 years ago.

According to README, it has the following functions:

Erd draws an ER diagram based on your database of applications and models.
You can drag the positions of each model.
You can use DB schema manipulations such as add column , rename column , alter column , create model (as well as table) and drop table
Erd then creates the migration files on the server
And you can run every migration in your browser.
