Piwigo is open source photo library and digital asset management software for managing, sharing and organizing photos and videos. It is offered as Piwigo Cloud, hosted in France, or as a self-hosted installation on the user's own infrastructure. Both versions share the same open source core and offer API access. Users can import media from multiple sources, organize it with albums, sub-albums, tags and metadata, and grant upload rights to third parties.
