GalleryHopper
An app for museum content creators and culture enthusiasts that tracks where displaced artifacts, paintings, and sculptures are right now — on loan, in storage, or on display across museums worldwide.
Art history YouTubers, museum bloggers, and serious culture enthusiasts who want to know 'where is the Rosetta Stone today?'
- Live map of artifact locations pulled from open museum data feeds and Ex Situ-style indices
- Watchlists that notify you when a tracked artifact moves between museums or exhibitions
- Trip planner that chains together 'chase the painting' museum stops across cities
- Exportable location-stamped images and metadata for video thumbnails and blog graphics
Ex Situ proves the underlying open-source index is feasible but no consumer-facing layer makes it usable; museum tourism and art YouTube content are both booming
Art/museum YouTube is a real category with sizable channels (e.g., MoMA at 556K subscribers) and Ex Situ's HN post drew 38 points/22 comments, but the specific 'track a single artifact's current location' use case is a narrow subset of curator/enthusiast behavior rather than mass demand.Top 20 YouTube Channels - Arts & Crafts Museums 2026 ↗Show HN: Ex Situ - Open-source spatial index of displaced cultural artifacts ↗
The B2B museum collections-management space is saturated (PastPerfect, Argus, Lucidea, etc.), but no consumer-facing app aggregates 'where is this artifact right now' across institutions — the gap exists precisely because Ex Situ is only an open index, not a productized consumer experience.GitHub - hburakyel/exsitu-public ↗
Museum collections databases charge institutions tens of thousands, but the consumer audience (YouTubers, bloggers) is small, price-sensitive, and can already get much of this free from museum sites, Wikipedia, and Ex Situ itself — limited clear willingness-to-pay signal.Museum Software ↗Argus Museum Collections Management Software | Lucidea ↗
Museum collections are century-stable institutions and art-history interest is durable; artifact loan tracking remains relevant as long as museums continue touring works, which is structural, not trend-driven.Best Museum Database Software | 2026 Expert Picks ↗
Ex Situ already provides an open geospatial index so the data layer is free, but a polished consumer product still needs ongoing loan data ingestion, museum partnerships, and a UX on top — moderate build, not trivial.GitHub - hburakyel/exsitu-public ↗
