Piwigo

Piwigo is a self‑hosted, open‑source web application for organizing, managing, and sharing photo and video collections. It runs on a standard web server with PHP 7.4+ and MySQL/MariaDB, and can use ImageMagick or GD for image processing. Users can install it via a simple NetInstall script or manually upload the package, and a hosted option is also available.

The software targets organisations, teams, and individuals who need to handle large volumes of media, offering hierarchical albums, batch operations, keyword tagging, and permission controls that allow private or restricted access to specific galleries. A plugin and theme ecosystem lets users extend functionality and customise the appearance of their galleries.

Developed since 2002 and maintained by an active community, Piwigo is released under GPL‑2.0, providing a free, auditable codebase without subscription fees. Its long‑term stability and extensibility make it suitable for museums, educational institutions, non‑profits, and professional photographers who require reliable, web‑based photo management.
