Letos is a multi-platform SQLite database manager written in C++ using the Qt framework.
Letos addresses the need for a free, open-source tool to inspect, edit, and manage SQLite databases across different operating systems. It provides a graphical interface built on Qt that allows developers and database administrators to work with SQLite files without relying on command-line tools or proprietary software. The tool supports encrypted SQLite databases through SQLCipher and wxSQLite3 integration, extending its utility to projects requiring database encryption.
Letos suits developers and teams working with SQLite who want a no-cost, feature-complete desktop application without vendor lock-in. It is particularly valuable for those who need cross-platform compatibility and prefer graphical database management over command-line interfaces. The project explicitly offers no paid edition and includes no telemetry, making it suitable for environments where data privacy and cost control are priorities. The tool can be installed through OS package managers where available, simplifying deployment.
The project maintains an active issue tracker for bug reports and feature requests, and the maintainers actively solicit contributions through documented guidelines. Development is supported by a comprehensive wiki covering compilation from sources and project details, indicating sustained effort to lower barriers to both usage and contribution.
