Seelen UI replaces major parts of the Windows 10 or 11 desktop, including the taskbar, dock, app launcher, window manager, notifications, and virtual desktops. Its CSS and JSON theming system and plugin widgets let users reshape both appearance and behavior, from minimal setups to denser power-user layouts. Microsoft Edge and the WebView runtime are required for the application to work correctly.

OpenWork is a desktop interface for running agent workflows on your own files, either through a local OpenCode host or a remote server. It supports many model providers with your own keys, plus installable skills, plugins, MCP servers, reusable templates, execution timelines, and explicit permission requests. macOS and Linux builds are directly available, while Windows access is currently offered through the project's paid support plan.

AB Download Manager organizes file transfers with download acceleration, queues, schedules, themes, and browser integration. It is useful for users who regularly manage batches of files or need downloads to run at specific times. Builds are listed for Android, Windows, Linux, and macOS through the project site, GitHub Releases, and platform package managers.

Loop lets Mac users choose a window position by holding a trigger key and moving the pointer through a radial menu, with a preview before the change is applied. Custom shortcuts and repeatable action cycles support faster keyboard workflows. It can be installed through Homebrew or a release download and requires macOS 13 or later.
