Overview

What is Damselfly?

Damselfly is a server-side photo library manager, designed to index extremely large image collections and allow you to easily find a photo using its metadata: IPTC keywords, folder and file names, dates. It also includes automatic object and face detection to enhance search capabilities.

Indexing is fully automated in the background: as soon as an image is added or modified in the monitored folders, the catalog updates quickly. Since Damselfly is a server service with a web interface, the photo library is accessible from multiple devices without having to copy the catalog or database locally.

Built with Microsoft .NET and a Blazor WebAssembly frontend, and deployable via Docker, Damselfly manages accounts and access rights, image baskets, and metadata editing. Hosted on your VPS in France, it indexes and recognizes your images on your instance, without entrusting them to a third-party photo cloud.

Host Damselfly at DINAO

No managed container for Damselfly: this application is installed on a VPS hosted in France (2 vCPU / 2048 Mo / 10 Go minimum).

Damselfly needs a level of access to the machine that the managed container, shared between several customers, does not give. Two VPS hosted in France: DINAO installs and manages it for you, or you administer it yourself.

Technical reason: bind mount of a host path (named volumes only in the managed offer).

Frequently asked questions

You might be wondering…

About Damselfly 6 questions

Is Damselfly suitable for very large collections?

Yes, that's its primary purpose. Damselfly is designed to index extremely large image collections and enable fast search, even on hundreds of thousands or millions of photos.

How does search work?

You search by IPTC keywords, folder and file names, or dates. Automatic object and face detection further enhances searches without requiring manual tagging.

Do I need to copy my photos to each device?

No. Damselfly is a server service with a web interface: your photo library is accessible from any device, without duplicating the catalog locally.

Are my photos analyzed by a third party?

No. Everything is hosted on DINAO's infrastructure in France. Object and face detection runs on your instance; your images never leave to any third-party photo cloud.

Can I retrieve my images and catalog?

Yes. Your original files remain yours, and Damselfly is open source. You can export and migrate without proprietary lock-in.

Is this application tested before it is offered?

This application has not yet passed our automatic deployment test. It can still be installed, but we invite you to contact us before ordering: we will then test it as a priority. The deployment template used was last updated on 3 July 2026. Each new version released by the publisher triggers this test again: the date above therefore follows the version actually offered.
