PiGallery2 review
A free, open-source gallery that keeps folders central while adding search, maps, metadata, and sharing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PiGallery2 is a self-hosted web photo gallery for people who want to browse photos and videos through their existing folder structure. Its directory-first approach keeps storage organization visible rather than replacing it with a purely library-based interface. The product is designed for low-resource servers, including Raspberry Pi devices, and supports responsive viewing on desktop and mobile browsers. It is free and open source under the MIT License, with Docker available for deployment instead of a vendor-hosted subscription service.
The feature set extends well beyond basic folder browsing. PiGallery2 displays EXIF information, supports slideshows, and offers Boolean, wildcard, metadata, date, rating, location, and person search. GPS maps can use OpenStreetMap, Mapbox, custom tile providers, and GPX paths. Saved searches can become logical albums, while password-protected links support controlled sharing. Adobe XMP face-region metadata can be displayed, but the product does not provide built-in facial recognition or AI-powered search. These capabilities make it a strong fit for organized personal archives where metadata and location matter.
Its ecosystem is centered on self-hosting: Docker, ffmpeg, MySQL, SQLite, OpenStreetMap, Mapbox, and ORCID are supported, and authentication can use built-in options or ORCID. On-demand thumbnail generation offers multiple sizes, which suits servers with limited resources. Choose PiGallery2 if preserving folders, controlling deployment, and avoiding subscription plans are priorities. Choose another product if you want cloud synchronization, automated face recognition, AI discovery, or a managed hosting experience.
