Migration Guide

The Modern CodePush Alternative

Microsoft retired Visual Studio App Center in March 2025. It's time to migrate to an enterprise-grade OTA update infrastructure built for modern React Native and Expo teams.

Why migrate from CodePush?

With App Center reaching end-of-life, teams relying on CodePush must find a migration path to maintain their ability to ship hot-patches and bypass app store review times. AppSpacer isn't just a drop-in replacement—it's a massive upgrade designed for scale, security, and developer experience.

Enterprise Security
