Keeweb

KeeWeb provides a password manager that works with KeePass database files across desktop and web environments. It runs as native applications on macOS, Windows, and Linux, and also offers an offline web version that operates in modern browsers without installation. The software supports opening multiple databases, searching across all of them from a single query box, and synchronizing files through cloud services such as Dropbox, Google Drive, OneDrive, or a personal server.

The interface includes dark and light themes, color‑coded favorites, tag management, drag‑and‑drop for attachments, and customizable entry icons. Users can generate passwords of arbitrary length, hide protected fields, view entry history with rollback capability, and employ advanced search filters including regular expressions. Keyboard shortcuts and a table view aid quick navigation, while an inline image viewer displays attached pictures.

All features are available offline, with changes syncing automatically when connectivity returns. KeeWeb is open‑source, free of trial limitations, and can update itself automatically or via user‑controlled notifications.
