HeidiSQLUnderrated
A free Windows client for MySQL, PostgreSQL, SQL Server, and SQLite.

Best for
Windows users who want a fast, no-nonsense SQL client without a subscription.
Why it deserves attention
HeidiSQL has been around for years and still opens quickly: browse tables, edit rows, manage users, run SQL, and compare schemas without a login or cloud account. It supports the common relational engines and can export data in several formats. It is Windows-only, and the interface shows its age compared with newer cross-platform clients.
