What Is a Patcher?

A patcher modifies an existing app by applying code changes (patches) locally. ReVanced takes a base YouTube APK and applies community patches on your phone instead of serving a pre-modified download.

ReVanced patcher workflow

ReVanced Manager bundles a patcher that downloads the recommended YouTube version, applies selected patches, and outputs an installable APK. ReVanced CLI offers the same flow for advanced users.

Why patch locally

Local patching lets you choose which features to enable and reduces reliance on third-party mirrors that may bundle malware or outdated builds.

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.
