What Is MicroG / GmsCore?

MicroG (now GmsCore in ReVanced) is a lightweight open-source implementation of Google Play Services APIs. It enables sign-in, notifications, and sync in sideloaded apps without root.

In the Vanced context

Vanced MicroG powered Google login for YouTube Vanced. The project is discontinued and no longer maintained; login failures are increasingly common on legacy installs.

In the ReVanced context

GmsCore is the actively maintained replacement for non-root ReVanced setups. Download it only from the official ReVanced GitHub repository and pair it with the recommended YouTube version.

Before you install

Always download patchers, GmsCore, and APK bases from official project pages or trusted mirrors listed in our safety guides. Mismatched versions are the most common cause of playback and login failures after setup.
