Every TestFlight alternative for iOS runs into the same Apple rule: outside TestFlight and the App Store, an iPhone only installs a build that's signed for that exact device. So the real question for each tool is who handles the device ID and the signing.

There are three kinds of tool:

- **Hosting tools** put an already-signed .ipa behind a link. You still add each new iPhone and rebuild.
- **Device provisioning tools** register the iPhone with Apple and re-sign the build for it.
- **Release platforms** add CI, tasks and integrations around distribution.

## At a glance

| Tool | Kind | Registers iPhones and re-signs | Android | Free plan |
| --- | --- | --- | --- | --- |
| BuildFerry | Provisioning | Yes | No | 1 app |
| Diawi | Hosting | No | Yes | Yes, links expire |
| BetaDrop | Hosting | No | Yes | Yes, links last up to 7 days |
| InstallOnAir | Hosting | No | Yes | Yes, links last 7 days |
| Firebase App Distribution | Hosting with UDID collection | No | Yes | Free |
| TestApp.io | Release platform | Not listed | Yes | 1 app |
| Appcircle | CI and release platform | Device registration in its signing tools | Yes | 100 downloads a month |
| Expo EAS | Build service | Rebuilds with new devices | Yes | Limited builds |

## BuildFerry

BuildFerry is built for the step every other tool leaves to you. A tester opens your share link and allows a one-time profile. You approve the iPhone, BuildFerry registers it with your Apple account and re-signs your exported .ipa in the cloud. New builds reach the same link.

**Best for:** iOS developers and small teams whose testers change often. **Not for:** Android, or betas over 100 iPhones.

## Diawi

The original "upload and get a link" tool. Fast and familiar, with password protection and UDID tools. You manage profiles yourself. [BuildFerry vs Diawi](https://buildferry.app/diawi-alternative).

## BetaDrop

Free hosting for iOS and Android, with QR codes, feedback, analytics, a GitHub Action, a CLI and an MCP server. It collects UDIDs into a list, but doesn't sign builds. [BuildFerry vs BetaDrop](https://buildferry.app/betadrop-alternative).

## InstallOnAir

A free link and QR code for each build, with paid extensions when a link needs to last longer than a week. [BuildFerry vs InstallOnAir](https://buildferry.app/installonair-alternative).

## Firebase App Distribution

Google's free tool for iOS and Android, tied into Crashlytics and fastlane. It collects UDIDs and emails them to you, then you rebuild. [BuildFerry vs Firebase](https://buildferry.app/firebase-app-distribution-alternative).

## TestApp.io

A release workspace with tasks, playbooks and Jira, Linear and Slack integrations. [BuildFerry vs TestApp.io](https://buildferry.app/testapp-io-alternative).

## Appcircle

An enterprise mobile CI/CD platform with testing distribution, signing identities and an enterprise app store. A good fit if you want builds, signing and distribution from one vendor and have the budget for it.

## Expo EAS

If your app is built with Expo, EAS can register devices and build an internal distribution .ipa. New devices mean a new build. [Sharing React Native builds](https://buildferry.app/share-react-native-ios-app).

## How to choose

- **Your testers change every week:** pick a tool that registers devices and re-signs, so you don't rebuild for each one.
- **You need over 100 testers:** use TestFlight. No ad hoc tool can raise [Apple's device limit](https://buildferry.app/apple-device-limit).
- **You ship Android too:** a hosting tool or Firebase covers both, and you can still use BuildFerry for iOS.
- **You want CI, tasks and integrations:** a release platform like Appcircle or TestApp.io.

App Center used to fill the provisioning role until it was retired in 2025. [Here's what replaced it](https://buildferry.app/app-center-alternative).
