You can express the table schema in git-friendly text-only format.<p>It can auto generate ERD diagram from the text in a webpage. You can drag to move the table diagrams, and the position are sync in the text format.<p>It can also auto generate incremental migration between the live database schema and designed erd in knex.js / raw sql format.<p>Recently you can also customize the coloring and have it shared with your teammate within the text format.
Cool! Very different from traditional ERD tools.<p>Still missing a lot of features and not as snappy/clean when moving tables around I can see lot of lag.<p>Have you tried erdlab.org? It's free and has some key features missing in your tool. For example, import/export SQL and advanced visual features.
