Khufu is available as a standalone docker container. Just tell it where to find TIFF files and you are ready to view gigantic images locally. TIFFs must be tiled to be viewable.

podman usage on Windows :

podman run -p 3333:8000 -d --name Khufu --env EXTERNALPORT=3333 -v C:\path_to_tiled_tiffs:/mnt/tifroot docker.io/delhoume/khufu

then point your browser to http://localhost:3333 and voila !
