A Mac application called Kugelblitz has been released as a three-dimensional globe and atlas that draws on open mapping sources rather than requiring a user account. The application presents Earth terrain with imagery, roads, topographic layers and 3D buildings, while also providing access to public map services collected in an in-app library.
The developer says Kugelblitz runs on Apple-silicon Macs with macOS 27 or later. Its downloadable disk image is 77 MB, although the geographic data viewed in the application is fetched as needed. Loaded material remains in a local cache, and users can optionally let multiple Kugelblitz installations on the same network share cached data.
OpenStreetMap supplies the main road map through a tile service operated for the application. Rather than asking users to choose and download a fixed region, Kugelblitz requests tiles for the area and detail level currently visible. The software also identifies the origin of displayed information in status windows and lists data providers and licenses in a dedicated sources panel.
The globe supports imagery, road and topographic views placed over terrain rather than displayed only as flat layers. Buildings can appear in three dimensions. Saved scenes restore a prepared viewpoint, and an atlas mode can display the same material using five flat projections at scales ranging from a complete sheet to detailed imagery.
A library feature connects to directories and geographic portals offering aerial photographs, satellite imagery, elevation models, conventional maps and building data. Services can be previewed on the globe and saved to a personal collection. The application is available in German and English and lets users choose measurement units.
Navigation works with a keyboard, mouse or trackpad. Kugelblitz also supports 3Dconnexion's SpaceMouse directly, allowing simultaneous movement controls without a separate driver, according to the developer. A Mac can stream an immersive view to Vision Pro through a built-in command without installing a separate headset application. The developer reports testing that function with an M1 Mac and a headset running version 27.2.
Beyond contemporary maps, Kugelblitz can place time-based natural events on the globe. Its site lists computed eclipses spanning 5,000 years along with records of earthquakes, eruptions, tsunamis and fireballs. A time control allows those events to appear and disappear chronologically.
Kugelblitz enters a category dominated by large web mapping platforms, but its distinguishing approach is a native Mac interface tied to openly available geographic sources and explicit licensing information. Claims about smooth performance, including operation on a 16 GB M1 Mac mini, come from the developer and have not been independently benchmarked.
