Rootless Pixel Launcher is different from other launchers such as Lawnchair, Lean Launcher, Ruthless, etc because it is based on Android’s open source Launcher3 and combined with decompiled Pixel Launcher sources.
Now the Rootless Pixel Launcher version 3.8 is available to download from the Google Play Store which will definitely expand its user base. However, you need another app called “Rootless Pixel Bridge” for the launcher to work.
In July 2018 Amair Zaidi (developer) launched Rootless Pixel Launcher 3.6 for non-pixel devices, which allow users to have the full features of the original Google Pixel Launcher to any phone without root.
In August, the Rootless Pixel Launcher 3.7 was launched and now the 3.8 version is available for a wide range of devices.
