Ueli is a cross-platform app launcher compatible with Windows, macOS, and Linux, providing a consistent user experience across these operating systems. The Windows and macOS versions are similar in functionality and design, though the Linux version is untested. Ueli offers a uniform interface with plugins that function identically on both Windows and macOS, but lacks a synchronization feature for settings across devices. Users can customize various aspects of their experience, including themes and search engines, but face limitations such as the inability to define specific prefixes for launching extensions. Ueli includes around 20 extensions, many disabled by default, which limits its versatility compared to competitors like Raycast and Flow Launcher. A notable feature is the Workflows extension, allowing users to create custom task sequences with a single command, although linking applications within workflows can be cumbersome on Windows. Overall, Ueli shows promise but has limitations that prevent it from fully competing with established tools.
