## BlueStacks (Android emulator)

BlueStacks generates its primary revenue through an Android emulator referred to as App Player. The basic features of the software are available for free, while advanced features require a paid monthly subscription. By February 2021, BlueStacks reported over 1 billion app downloads. The App Player provides support for mouse, keyboard, and external touch-pad controls.
In June 2012, the company introduced an alpha version of its App Player software for macOS, while the beta version was released in December of the same year. In December 2024, it released BlueStacks Air for Apple Silicon Macs.

### BlueStacks 3N

In January 2018, BlueStacks announced the release of the BlueStacks + N Beta, running on Android 7 (Android Nougat).This was notable as most Android emulators were running Android 4.4 (KitKat) at that time. This version was powered by an upgraded "HyperG" graphics engine that enabled the use of the full array of Android 7 APIs.

### BlueStacks 4

BlueStacks introduced a new version, BlueStacks 4, in September 2018, BlueStacks 4 demonstrated benchmark results up to 6 times faster than a 2018 generation mobile phone during testing. Dynamic resource management, a new dock and search user interface, an AI-powered key-mapping tool, and support for both 32-bit and 64-bit versions of Android 7.1.2 Nougat were included in this version.
In January 2019, BlueStacks released a 64-bit version of BlueStacks 4 through its early access program, offering improved performance and memory usage by running on a 64-bit version of Android 7.1.2. This version required a 64-bit version of Windows 8 or later with virtualization enabled and Hyper-V disabled. This 64-bit release allows the installation and usage of ARM64-v8a Android applications.

### BlueStacks 5

BlueStacks unveiled BlueStacks 5 in May 2021, still based on Android 7.1.2 but also offering compatibility with Android 9 (Android Pie) or Android 11, based on user choice.

### BlueStacks X

In September 2021, BlueStacks launched BlueStacks X, a cloud gaming service based on the Android platform. Bluestacks X utilizes throttling to adjust speed according to a user's internet connection, under the name of Hybrid Cloud. The servers for BlueStacks X's are hosted by now.gg, a subsidiary of BlueStacks.

### BlueStacks Air

In December 2024, BlueStacks launched BlueStacks Air, an Android emulator for Apple Silicon Macs.

## Minimum requirements

For Windows, BlueStacks App Player has minimum requirements of Windows 7 or above, 4 GB of RAM, 10 GB of disk space, and an Intel or AMD processor. BlueStacks Air currently supports Mac systems using Apple Silicon chips (M1-M4). For macOS, minimum requirements include macOS 11 (Big Sur) or higher Operating System, 8 GB RAM, and 12 GB disk space.

## Criticism

BlueStacks has faced criticism for the forced installation of BlueStacks X alongside BlueStacks 5, despite separate download buttons on the website. Even after uninstallation, BlueStacks X reappears with each BlueStacks 5 update. Starting around February 2023, the installer began forcibly installing a crypto wallet application from now.gg, Inc. (a sister company of BlueStacks, Inc.) as well as an icon on the system tray that runs on startup and cannot be disabled. This application has since been renamed to BlueStacks Services.
