Diodon review
A focused Linux clipboard history manager with plugins for extra actions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Diodon is an open-source clipboard manager for Linux desktops, with a particular focus on Unity integration. It stores clipboard items through Zeitgeist and normally keeps them in a database, so clipboard history remains available after reboot. The application-indicator integration provides desktop access, while plugin support extends the basic history workflow. It is suited to Linux users who want persistent clipboard history without a broader cross-platform feature set.
Its strongest fit is the combination of persistence and desktop integration. Zeitgeist provides the clipboard history storage, while Unity desktop and application-indicator integrations connect Diodon to supported Linux environments. Plugins add numbered clipboard menu items, allow users to paste all recent items, enable editing of the active clipboard item, and remove an item after pasting. Installation paths include an official Ubuntu PPA, with source or release-tarball options for other systems. These options make the project relevant to users comfortable choosing a Linux-specific installation route.
The main consideration is the project's maintenance direction and platform scope. The maintainer announced low maintenance mode in July 2026, with packaging, translation, and security issues expected to receive attention. Wayland support is partial, which matters for Linux users on newer desktop sessions. Diodon makes the most sense for someone seeking a straightforward, persistent clipboard history manager on Linux, especially where Unity or application-indicator integration fits the desktop. Users who need broader platform coverage, full Wayland support, or an actively expanding feature set should consider an alternative clipboard manager.
