# Diawi Alternative That Handles UDIDs and Signing

> Diawi hosts your .ipa, but you still collect UDIDs and rebuild profiles. BuildFerry registers each iPhone and signs the build for you, with no Mac.

Diawi is a quick way to host a build that's already signed for the right iPhones. The catch comes when someone new needs it: the iPhone has to be in your provisioning profile first.

## The loop BuildFerry removes

With a hosting-only tool, a new tester usually means:

1. Asking them to find their UDID.
2. Adding it in your Apple Developer account.
3. Regenerating the provisioning profile.
4. Rebuilding or re-signing on your Mac.
5. Uploading again and sending a new link.

With BuildFerry, your tester opens the same link, you approve their iPhone, and the build is registered and signed in the cloud.

## What you get

- **Automatic UDID capture** through a one-time profile in Safari.
- **Device registration** with your Apple team, through Apple's API.
- **Cloud signing**, so you don't need a Mac.
- **New builds on the same link**, so testers don't need a fresh URL.
- **Your exact iPhone count** against Apple's limit of 100.

## When Diawi is the better choice

If your build is already signed for the iPhones you need, and you just want a temporary link with no Apple key connected, a hosting tool is simpler.
