Hardware Requirements

    MuleSoft recommends a minimum of 4GB of free RAM available on a developer workstation. As applications become complex, consider adding more RAM.

  • 2GHz CPU.

  • 10GB free hard drive space.

Software Requirements

  • Java Environments:
    This version of Anypoint Studio requires AdoptOpenJDK 8 to run properly. Depending on which Mule runtime engine you want to use, you can configure different JDK versions within Anypoint Studio:

    • Mule 3.9.x requires Studio running on Java 8.

    • Mule 3.5.x requires Studio running on Java 7.

    • Other supported runtime versions work fine with both Java 7 or 8.

  • Operating Systems

    • macOS 10.10.0 through 11.0.0

    • Windows 7 (64-bit), Windows 8 (64-bit), Windows 10 (64-bit)

    • RHEL 7.0

    • Ubuntu 15.04 or later

Running real-time antivirus protection software on your operating system might have a negative impact on Anypoint Studio performance. Although this issue is prominent on Windows, it also occurs on Linux and macOS.

Although the steps to solve these performance issues vary depending on your antivirus software, a typical solution is to either allow or exclude the Anypoint Studio and java executables, the Studio install and workspace filesystem locations, or some combination of both. See examples of solutions for McAfee Viruscan, Windows Defender, and Symantec Endpoint Protection.
