PiGallery 2

PiGallery2 serves as a self‑hosted photo and gallery that presents images directly from an existing folder hierarchy. By pointing the application at a directory, it builds a web interface that mirrors the on‑disk structure without altering any files, making it a read‑only solution. The design emphasizes speed and low resource consumption, allowing it to run comfortably on modest hardware such as Raspberry Pi.

The software is distributed under the MIT license and is intended for users who want a simple, directory‑first gallery that can be deployed with minimal configuration. It is packaged for Docker, which is the recommended installation method, while a native Node.js setup is possible for advanced users. Documentation covers configuration, user rights, and contribution guidelines.

PiGallery2 is open source, free‑tier, and does not require a subscription, positioning it as a lightweight alternative for personal or small‑scale photo collections where server resources are limited.
