Hugin vs Xpano

Hugin is a free, open-source toolchain for stitching overlapping photographs into panoramas, including immersive panoramic images. Its automated Assistant can assemble multi-row photos, while control points support perspective correction. The tutorials also address lens calibration, blend masks, and exposure fusion. Hugin uses Enblend to blend seams and Enfuse to combine bracketed exposures. It supports RAW input, HDR or exposure blending, control-point editing, and batch stitching, and is listed for both panorama types. Hugin runs on Linux, macOS, and Windows. Windows downloads include a 64-bit installer; 32-bit support is limited to versions through Hugin 2017.0. The listed Mac bundle targets macOS 10.9 and newer but does not run on newer arm64 Macs. Linux users can use distribution package managers, Flatpak, or AppImage builds. The project offers a manual, tutorials, FAQs, and the PanoTools wiki, with discussion on its mailing list and bug reports through Launchpad. It is free to use, modify, and share.

Xpano imports a directory of images, finds groups that can be stitched into panoramas, and exports the computed results. Before export, users can preview panoramas, zoom and pan around them, crop, fill boundaries automatically, choose projection types, and adjust pitch, yaw, and roll. The app uses OpenCV and its stitching module for image processing, and exports full-resolution panoramas with EXIF metadata. It also supports automatic command-line processing, with a --gui flag to launch the graphical interface. The maximum panorama size is selectable and defaults to 100 MPx. Xpano is available for Linux, macOS, and Windows, and is distributed under the GPL-3.0-or-later license. The listed Xpano plan is free, with no price or usage limits stated. The project names Tomas Krupka as maintainer and contact. Its release page says build logs can be used to verify the source commit hash and SHA-256 checksum.
