Zequel is a modern, open-source database management GUI designed for macOS, Windows, and Linux. It offers a comprehensive suite of features to streamline database management tasks. The Query Editor is Monaco-based, providing syntax highlighting, auto-complete, multiple tabs, parameterized queries, and EXPLAIN visualization. It supports over 30 SQL snippets per dialect. The Schema Browser allows users to explore and manage databases, tables, columns, indexes, foreign keys, views, routines, triggers, sequences, enums, and extensions. The Data Grid features virtual-scrolled grid with in-cell editing, filtering, sorting, column resize/reorder, multi-row selection, bulk operations, and undo/redo capabilities. ER Diagrams offer interactive entity-relationship diagram visualization. Import and export functions support CSV, JSON, SQL, and Excel formats. Security is ensured with SSL/TLS connections, SSH tunneling, and OS-level credential storage. The Process Monitor allows viewing and managing active database processes, while the Command Palette provides quick access to all actions via Cmd+K / Ctrl+K. Zequel supports a dark/light theme that follows system preferences or can be manually toggled. It is cross-platform with native builds for macOS (Intel + Apple Silicon), Windows, and Linux.
