We built something unusual during a weekend hackathon, a fully working Docker registry that runs natively on iOS.

Just install the app and your iPhone becomes a self-hosted Docker registry.

RepoFlow App - Docker registry

Why?

This started as an experiment: could we build a real, standards-compliant registry that works entirely on-device, with no backend or network dependency? Turns out, yes.

This app is part of a larger project called RepoFlow, which aims to simplify package management for teams that self-host.
