## What it is
Letos (formerly SQLiteStudio) is a free, open-source, cross-platform desktop application for creating, browsing, and editing SQLite databases, built with C++ and Qt. It includes an advanced SQL editor, ERD diagramming, encrypted database support (SQLCipher, WxSQLite3), and custom SQL functions via scripting languages.

## Use cases
- browse and edit sqlite database files
- run sql queries against sqlite with syntax highlighting
- design database schema with an ERD editor
- open password-protected sqlcipher databases
- copy tables between sqlite databases
- write custom sql functions in python or javascript

## When to choose
- you need a free GUI tool to manage SQLite databases on Windows, Linux, or macOS
- you want a portable app with no installation or telemetry
- you work with encrypted SQLite databases like SQLCipher
- you need ERD visualization or cross-database queries

## When to avoid
- you need a manager for other database engines like MySQL or PostgreSQL
- you need a headless or CLI-only SQLite tool
- you require a web-based or collaborative database client
