UncrustifyX

The application provides a graphical interface for browsing and managing the extensive option set of the Uncrustify code‑formatting tool on macOS. Options are organized into categories, searchable and filterable, and can be dragged from the documentation panel into a table where a live preview shows the effect on a sample snippet. Users can import and export Uncrustify configuration files, run a chosen configuration on multiple source files or on direct code input, and integrate the tool with Xcode via a bundled plugin.

Typical users are developers who need to customize Uncrustify formatting for languages such as Objective‑C, and who prefer a visual workflow over editing raw configuration files. The software simplifies configuration creation, testing, and application without requiring command‑line interaction.

Distinctive features include the drag‑and‑drop option management, real‑time preview of formatting changes, and in‑application updates through Sparkle. The project is released under a modified BSD license and supports macOS 10.8 or later, with source and binaries available on its releases page.
