| Integrations | The README says gallery images were post-processed in darktable; it does not describe a software integration. | Contribution masks can be loaded as layer masks in an image editor, and Pro supports EXIF passthrough. |
| Purpose | ChimpStackr is an open-source application for focus stacking. | Rekall Fusion aligns focus-stack frames and fuses them into a single image sharp from front to back. |
| Requirements | Building from source requires Python 3.9–3.13. | It requires 64-bit Windows 10 version 1809 or Windows 11 and the .NET 10 desktop runtime; 8 GB RAM minimum is specified. |

In their own words
ChimpStackr
ChimpStackr is a free, open-source application for focus stacking, with graphical and headless command-line interfaces. It offers Laplacian Pyramid, Weighted Average, Depth Map, and Exposure Fusion methods. Automatic alignment supports translation, Euclidean rotation, similarity rotation and scale, and affine correction. Its 16-bit pipeline preserves bit depth from RAW input to output, and automatic cropping removes black edges caused by alignment shifts. Users can drag image files or folders into the app, compare input and output with a slider, and pause, resume, or cancel long-running stacks. Auto-tuning detects parameters from image resolution. Downloads are listed for Windows as a ZIP, macOS as a DMG, and Linux x86-64 as an AppImage; TIFF and PNG are listed output formats, and RAW files are supported. The project uses the GPL-3.0 license. Exposure Fusion is described for images with varying exposure or lighting, rather than focus stacking. Building from source requires Python 3.9–3.13, and builds can only be made for the current platform.
