MySQL Workbench is a visual database design and administration tool developed by MySQL. It provides a graphical interface that allows users to perform tasks such as creating and managing databases, designing database schemas, executing SQL queries, and managing server configurations.

Some key features of MySQL Workbench include:

1. Database Design: Users can create, edit, and visually design database schemas using the entity-relationship diagram (ERD) model.

2. Query Development: Users can write and execute SQL queries, view and analyze query results, and debug SQL statements.

3. Server Administration: Users can manage MySQL servers, including starting and stopping servers, configuring server options, and monitoring server status.

4. Data Modeling: Users can reverse engineer existing databases to generate ERD diagrams, and forward engineer ERD diagrams to create databases.

5. Data Migration: Users can migrate data from one database system to another, such as from Microsoft SQL Server to MySQL.

6. Performance Analysis: Users can analyze the performance of their databases and queries using tools such as query profiling and performance optimization advisors.

MySQL Workbench is available for Windows, macOS, and Linux operating systems, and it can be downloaded for free from the MySQL website.
