About

Letos is a free, open-source SQLite database management application that allows users to create, browse, edit, and maintain SQLite databases through a graphical interface. Formerly known as SQLiteStudio, the software provides tools for managing database tables, views, indexes, triggers, and relationships without requiring extensive command-line operations. Its advanced SQL editor includes syntax highlighting, code completion, query formatting, error detection, and execution history to simplify database development. Letos also provides a visual entity relationship diagram (ERD) editor for designing database schemas and managing relationships between tables. Additional capabilities include importing and exporting data, managing encrypted SQLite databases, generating test data, and creating custom SQL functions through scripting. The application runs on Windows, macOS, and Linux, supports portable deployment, and is distributed under the GPL license without subscription fees or telemetry.
