Ranked in these QuestionsQuestion Ranking
Pro Powerful SQL terminal
PG Commander offers a built-in SQL terminal.
Pro Fast, native UI
The UI is clean and simple with a native feel.
Pro Multiple Query Tabs!
The multi-tab and multi-SQL-runs are great. It's always good to be able to compare results in one window instead of having to go through and re-run stuff.
Pro Fast Auto-complete
Pro Multiple Databases
They only support 2 at the moment (MySQL and MariaDB) but their social site says they'll be updating with more DBMSes in the near future which is pretty nice because I hate learning new GUIs~
Pro Clean and pretty UI/UX
The default color is dark and comfortable for the eyes.
Not sure about Linux but it works on Windows and Mac just fine!
