Immich is a self-hosted platform for managing personal photo and video libraries. It is aimed at people who want a private alternative to cloud photo services, with a strong focus on high-performance browsing, mobile backup, and web-based administration. The project supports both mobile and web clients, letting users upload media, automatically back up photos from a phone, and organize content with albums, shared albums, favorites, tags, folders, and partner sharing. It also includes search across metadata, objects, faces, and CLIP-based recognition, plus map and EXIF views, public sharing, read-only gallery access, and administrative user management. The README highlights offline support on mobile and presents the project as a fully self-hosted solution.

PhotoPrism is a self-hosted photo and video management application designed for people who want a private way to browse, organize, search, and share their media. The README presents it as an AI-powered system that can tag content, recognize faces, and surface photos through powerful filtering and search, while emphasizing privacy and independence. It is aimed at users who want a browser-based experience across desktop and mobile devices, with a PWA that can be installed like a native app. The project also supports media ingestion and access through tools such as WebDAV and compatible backup apps, making it useful both as a personal photo library and as a syncing/backup hub for phones and computers.

LibrePhotos is a self-hosted photo management application aimed at users who want to organize and search personal media on their own infrastructure. It focuses on automatically enhancing large photo libraries with machine-learning features such as face recognition, object detection, semantic search, and image captioning-related capabilities. The project is built as a web application with a Django backend and a React/TypeScript frontend, and it is designed to run in Docker-based environments. It is suitable for people managing family or personal photo archives, especially those who want timeline browsing, event-based album generation, metadata search, and support for raw photos and videos. The README also points to interactive API documentation, which suggests it can be integrated with other tools.

The project emphasizes fast retrieval and workflow-friendly management. It supports broad image format coverage, full-text and advanced search, non-destructive EXIF keyword updates, background indexing, thumbnail generation, and selection baskets for downloading or exporting images. It also includes AI-assisted capabilities such as face detection, face recognition, object detection, and image color classification. Damselfly is designed for multi-user deployments, with user accounts, roles, and shared or user-specific baskets. The README indicates it runs on Windows, Linux, macOS, and Docker, and that its latest face recognition works locally and offline.

It combines gallery browsing with built-in editing tools, making it suitable for personal libraries as well as small teams that want to organize images without relying on external cloud services. The project emphasizes speed and simplicity: it uses virtual scrolling to browse large sets of images quickly, supports drag-and-drop organization and multi-select bulk actions, and applies edits non-destructively through URL-based transformations. The quick start shows a Docker-based setup with SQLite and a mounted local image folder, and the README points users to hosted documentation for deeper configuration and usage details.
