DbVisualizer vs Adminer

This is a good and stable tool with really good and useful functionality: import/export, SSH tunnelling, fast searching, duplication, DDL visualization etc. If you are a professional, don't complain about the pricing. If you're an amateur, maybe this isn't for you.

Makes it really easy to stub out example data while developing, just change the values with unique constraints and you have extra data ready to go.

Has a search box that will highlight any matching row, regardless of what field is matched (spans multiple columns).

Allows you to edit and save db rows through a spread-sheet like editor.

The installation and Adminer itself only requires a single PHP file. Once it's uploaded you can log in and start using it.

It supports several database management systems (Postgres, SQLite, Oracle, MS SQL and of course MySQL).

Anyone who uses the views function will appreciate Adminer better. You can click on a view and edit to change the view. In phpMyAdmin, you can edit a view, but it's not easy or intuitive. SQL Buddy doesn't have any way of doing this.

Has a great variety of themes which transfers pretty ugly application into a great looking one.

No need to install, it's available to use out of the box.
