Point FastLoupe at the folders you already have — or at your Lightroom Classic catalog, ratings and albums intact — and scroll all of it at full speed. Your files stay exactly where they are. Buy it once. No subscription, no cloud account, no upload. Most photo apps get slow because they reach for the original file — a 45 MB raw — every time you scroll past it. FastLoupe never does. Browsing reads from two purpose-built local stores, so the size of your library stops being the thing that hurts. Every filter, date bucket and search runs against a local SQLite index with full-text search. Thumbnails live in memory-mapped pack files ordered by capture date, so scrolling reads sequentially instead of thrashing your disk. Ratings, flags, rotation and adjustments are stored as data; browsing never touches an original. Point FastLoupe at a folder and it catalogues the photos where they are. Or open an Adobe Lightroom Classic .lrcat directly: FastLoupe never writes to it, so Lightroom keeps working exactly as before while you try this. Star ratings, picks and rejects, colour labels, keywords and collections arrive with the photos — not just the filenames. FastLoupe is built for the part of the job that happens most often: getting photos in, finding the good ones and getting them back out. It is not a retouching suite.
