## What it is
HeidiSQL is a free, lightweight graphical client for managing MariaDB, MySQL, Microsoft SQL Server, PostgreSQL, SQLite, Interbase and Firebird databases. It lets users browse and edit data and structures, run SQL queries, and export/import data and schemas across servers.

## Use cases
- manage mysql and mariadb databases with a gui
- browse and edit postgresql table data
- run sql queries against multiple database servers
- export database structure and data to sql files
- create and edit tables, views, procedures and triggers
- connect to sqlite and firebird databases from one tool

## When to choose
- you want a free, lightweight Windows-native GUI for MySQL/MariaDB, MSSQL, PostgreSQL or SQLite
- you need one client for many different database engines
- you prefer editing data in a grid and managing schema visually
- you need a portable database client without installation

## When to avoid
- you need a web-based database client for team access
- you require deep NoSQL or cloud-warehouse support
- you want extensive plugin ecosystems or AI-assisted query features
- you need to build from source without a Delphi license
