HeidiSQL is free software, and has the aim to be easy to learn. "Heidi" lets you see and edit data and structures from computers running one of the database systems MariaDB, MySQL, Microsoft SQL, PostgreSQL and SQLite. Invented in 2002 by Ansgar, HeidiSQL belongs to the most popular tools for MariaDB and MySQL worldwide. Free for everyone, OpenSource. Connect to multiple servers in one window. Supported database systems: MariaDB, MySQL, MS SQL, PostgreSQL and SQLite. Connect to servers via commandline. Connect via SSH tunnel, or pass SSL settings. Create and edit tables, views, stored routines, triggers and scheduled events. Generate nice SQL-exports, compress these afterwards, or put them on the clipboard. Export from one server/database directly to another server/database. Manage user-privileges, import text-files, export table rows as CSV, HTML, XML, SQL, LaTeX, Wiki Markup and PHP Array. Browse and edit table-data using a comfortable grid.

SQL Notebooks allow developers to write Markdown combined with SQL to produce live HTML5 reports. They offer a lightning-fast, modern HTML5 interface where data sources are queried in real time. Users can create beautiful, live-updating SQL notebooks, easily source control the code, and take static snapshots to share with colleagues who don't have database access. SQL Notebooks are available in both QStudio Version 4, a desktop SQL client based on editing markdown files locally, and Pulse Version 3, which serves as a shared team server accessible via a web address. To help users get started, a showcase of example notebooks has been created in collaboration with leading community members; these examples are snapshotted versions with static data, and the source markdown and most of the data to recreate them are available on GitHub.
