NikGapps is a custom Google Apps package developed by Nikhil Menghani. Unlike the more traditional "Open GApps" project, NikGapps is designed with a specific philosophy: to install only the applications that cannot simply be downloaded from the Play Store.
While Open GApps often includes various libraries and frameworks that the user might never use, NikGapps focuses on a "lean and mean" installation. It avoids installing apps like Gmail, Google Maps, or YouTube via the recovery zip (forcing users to download the latest versions from the Play Store instead), and focuses strictly on the proprietary Google framework required for the OS to function correctly with Google services.
NikGapps is a popular, open-source project maintained by a developer named Nikhil. It offers modular Google Apps packages for various Android versions (10 through 14). Unlike the monolithic Open GApps (which has been largely unmaintained for newer Android versions), NikGapps is continuously updated and offers incredible customization.
The project is unique because it allows users to create their own addon.d survival scripts, meaning your GApps can survive an OTA update without needing to be reflashed.

In the world of custom Android development, Android 12L (internally known as 12.1 or "SL") arrived as a major shift, specifically tailored for large screens and foldables. While custom ROM enthusiasts jumped to flash these new builds, they faced a familiar hurdle: getting the Google Play Store and essential services onto a system that ships without them.

Users wanted the Play Store, but they didn't want the performance hit. The Solution: NikGapps Core

It includes only the bare essentials needed to get the Google Play Store running: Google Play Services Google Play Store Google Services Framework Google Calendar Sync and Contacts Sync The Android 12L Experience

Extreme Performance: By avoiding heavy apps like Chrome or Maps at the system level, the UI remained snappy, letting the new taskbar and split-screen features of 12L shine.
Total Control: Since only the "Core" was installed, users could download exactly what they wanted from the Play Store as user apps, making them easier to uninstall later.
