The product
What Project Kestrel is building
Project Kestrel is a free, open-source desktop application for reviewing and organizing bird photographs. It groups photos into scenes, ranks images by sharpness, identifies species, and presents the result as a searchable timeline. The project also offers culling tools, export of ratings to photo editors, and optional cloud compute. Its site provides direct downloads for macOS and Windows and says the core workflow runs locally, with photos staying on the user's machine. A recent release added an App Store distribution path and workflow updates for photographers.
From the maker
A one-person, open-source workflow for sorting bird-photo backlogs
Project Kestrel's August 2, 2026 release brought the app to the Mac App Store and added updates to its analysis settings, metadata workflow, and cloud-compute experience. It is a notably specific, public-access product from a solo developer rather than a general-purpose photo SaaS, with a clear local-first stance and a practical download path for early adopters.
