Look is built for self-hosted libraries: ⢠Browse a fast, full-screen photo grid ⢠Search by filename, tag, camera metadata, and path ⢠View albums and smart collections from your server ⢠Open photo details with EXIF, dimensions, file type, tags, and location metadata ⢠Long-press photos to enter multi-select ⢠Save selected photos back to your device when you choose ⢠Connect with a Tailscale MagicDNS name or private Tailscale IP address ⢠Use an optional API key when your server requires one Look does not provide cloud photo hosting. You need a running Look server that your device can reach over Tailscale or another trusted private network.
