Tonfotos leads for a family archive where finding people matters most, followed by PhotoPrism for a private server library and Piwigo for shared online collections.
Its face recognition and photo face search features help turn a scattered collection into something you can browse by the people who appear in it.
Photo face search here means finding someone within your own photo library.
Albums, tags, date browsing, maps for geotagged pictures and duplicate management give you other routes through the collection.
Key advantages: detailed search, face grouping and access through a browser.
