DBeaver is a free multi-platform database tool for developers, SQL programmers, database administrators and analysts. Supports all popular databases: MySQL, PostgreSQL, MariaDB, SQLite, Oracle, DB2, SQL Server, Sybase, MS Access, Teradata, Firebird, Derby, etc.
I really like it. It is a Database Client that connects to almost any database and is very useful for day to day tasks.
The only downside is the outdated UI, which is based on Eclipse.
I have been using this tool in my daily work for several years now. Powerful, useful, universal.
Sometimes it freezes and I have to kill him via the command line.
