Beekeeper Studio - Great open-source SQL editor
As is the nature of web development, I often have to work with a lot of different databases. Having a good database manager and SQL editor makes working with databases a lot easier. Over time I've tried a lot of different database managers, namely MySQL Workbench, PHPMyAdmin, Adminer, and Jun Han's MySQL extension for VS Code. While all of the tools have their strengths and weaknesses, I really prefer a lighter-weight editor and that simple to use at the expense of more complex functionality. In short, all I really need to do is be able to connect to a database easily, view a table's data and structure, occasionally inspect things like indices and foreign keys, be able to run SQL queries, and no more.
Beekeeper Studio so far has been my favorite SQL editor to use. It is fast, simple, and looks good. It is also open-source, cross-platform (and is available through some Linux package managers and Snap), and supports multiple database engines. Best of all, it is receiving a lot of active support and development.
I urge you to check out the project and test it out. It is a great tool to use for SQL queries, and it is a great addition to my toolbox and perhaps yours too.
