Run a Private Docker Registry on Your iPhone

Portable, Local, and Private with the RepoFlow iOS App

Update November 10, 2026

We’ve taken down the RepoFlow iOS app. It began as a free project at a hackathon, but its relationship to the broader RepoFlow product wasn’t clear. We’ve removed it to avoid confusion and focus our efforts on supporting the core RepoFlow product.

If you’ve used the iOS app and have questions, we’re here to help at support@repoflow.io. If you found the app useful and would like to see it return, we’d love to hear about your experience at hello@repoflow.io.

We built something unusual during a weekend hackathon: a fully working Docker registry that runs directly on iOS. No servers, no external setup, and no cloud required. Just install the app and your iPhone becomes a portable registry.

This is ideal for demos, CI environments, air-gapped testing, or just having a local registry you can carry in your pocket.

Why We Built It

We’ve been working on RepoFlow, a self-hostable and cloud-ready alternative to Artifactory and Nexus. It supports Docker, npm, PyPI, Maven, and more.

As a side project, we decided to explore whether the Docker registry API could be implemented natively on iOS. It turns out, it can.
