Letos

Letos is a free, open-source SQLite database management application formerly known as SQLiteStudio. Built with C++ and Qt, it provides a graphical environment for creating, editing, and exploring SQLite databases. Users can manage tables, indexes, views, and triggers without writing SQL manually. Its SQL editor supports query execution, syntax highlighting, and code completion. Database contents can be imported from CSV and text files or exported to formats including SQL, JSON, XML, HTML, and PDF. The application offers test data generation and scripting through JavaScript, Python, and Tcl. A plugin system extends database handling, formatting, and import capabilities. Letos runs on Windows, macOS, and Linux without requiring installation or administrator privileges.
