DBeaver - Universal Database Manager and SQL Client. DBeaver is free and open source (GPL) universal database tool for developers and database administrators. Usability is the main goal of this project, program UI is carefully designed and implemented. It is based on open source framework and allows writing of various extensions (plugins). It supports any database having a JDBC driver. It may handle any external data source which may or may not have a JDBC driver.
- Works great with different databases and also available on Linux
- An absolute alternative for HeidiSQL. Free and supports almost all databases.
- Offers same thing, a little bit confusing at the first time tho.
