HeidiSQL

HeidiSQL is a popular, free, and lightweight Windows-only client for managing MySQL, MariaDB, PostgreSQL, SQL Server, and SQLite. It is beloved for its simplicity, speed, and straightforward interface that gets users connected and productive quickly. Despite its lean footprint, it packs a surprising number of features: a capable SQL editor with syntax highlighting, a convenient table data browser with bulk edit functions, and easy-to-use tools for managing users, importing/exporting data, and synchronizing table structures between databases. Its session manager makes it easy to organize connections to multiple servers.

HeidiSQL excels at making common administrative tasks for MySQL/MariaDB incredibly efficient, and its support for other databases, while not as deep, is serviceable. It is ideal for developers and DBAs on Windows who primarily work with MySQL or MariaDB and want a fast, reliable, no-fuss tool that launches instantly and handles day-to-day tasks without bloat. For users who don't need the multi-database breadth of DBeaver or the heavy features of Workbench, HeidiSQL is a perfect, focused alternative.
