Foldergram is a self-hosted web application that turns your local folders of photos and videos into an Instagram-style gallery. It scans a root directory, indexes supported media files, generates thumbnails and previews, and delivers a fast, feed-based Progressive Web App experience with home feed, explore, library, and per-folder profile views, all without cloud sync or multi-user accounts. In this step by step guide I will show you how to install Foldergram on your Synology NAS using Docker & Portainer.
This guide works perfectly with the latest Foldergram v1.0.6Ā release.
