Letos vs. DbVisualizer

Letos is a free, open-source SQLite database management and development application that provides a graphical environment for creating, editing, querying, and maintaining relational databases. Formerly known as SQLiteStudio, the software is designed for developers, database administrators, and other users who work with SQLite database files. Its database management tools allow users to create tables, modify column definitions, manage indexes and triggers, configure views, and organize database structures without manually writing every SQL statement. The integrated SQL editor provides syntax highlighting, intelligent code completion, automatic formatting, error detection, and navigation between queries and referenced database objects. Query history and DDL history features retain previously executed statements, allowing users to review database operations and reuse earlier commands. Letos includes a visual entity relationship diagram editor that enables users to create, inspect, and modify database schemas through interactive diagrams showing tables, columns, and relationships. Its data browsing capabilities provide editable grid and form views with features such as pinned columns, customizable layouts, image previews, JSON editing, and direct cell value modification. The platform supports importing information from CSV and text files and exporting database content to formats including SQL, CSV, HTML, XML, PDF, and JSON. Advanced database capabilities include support for encrypted SQLite variants such as SQLCipher, WxSQLite3, and System.Data.SQLite, along with cross-database queries and drag-and-drop copying of database objects. Letos also supports custom SQL functions, user-defined collation sequences, automated test data generation, and extensibility through JavaScript, Python, Tcl, and plugins.
