Hi Product Hunt 👋 I built Domino because comparing images on Mac still felt surprisingly fragmented. I often needed to switch between windows, zoom into the same detail repeatedly, collect candidates from different folders, and record comparison results somewhere else. Domino started as a fast image viewer, but gradually evolved into a workspace built around visual decision-making. Today, you can collect images in the Staging Tray, compare up to 6 images with synchronized zoom and pan, inspect pixels, ROI and histograms, use overlay/difference views, and finally review, rate, rank and export the results. The workflow has become: Browse → Collect → Compare → Inspect → Review → Report Domino is built natively for macOS and is especially designed for photographers, designers, AI creators, computer vision engineers, and anyone who frequently needs to compare similar images. I’d especially love feedback on the comparison and Review/Ranking workflows — these are the areas I want to keep pushing further. Thanks for checking it out!
