The Servo Parallel Browser Engine Project

Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64-bit macOS, 64-bit Linux, 64-bit Windows, 64-bit OpenHarmony, and Android.

Servo welcomes contribution from everyone. Check out:

• The Servo Book for documentation
• servo.org for news and guides

Coordination of Servo development happens:

• Here in the Github Issues
• On the Servo Zulip
• In video calls advertised in the Servo Project repo.

Getting started

For more detailed build instructions, see the Servo Book under Getting the Code and Building Servo.

macOS

• Download and install Xcode and brew.
• Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh
• Install rustup: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
• Restart your shell to make sure cargo is available
• Install the other dependencies: ./mach bootstrap
• Build servoshell: ./mach build

Linux

• Install curl:
  • Arch: sudo pacman -S --needed curl
  • Debian, Ubuntu: sudo apt install curl
  • Fedora: sudo dnf install curl
  • Gentoo: sudo emerge net-misc/curl
• Install uv: curl -LsSf https://astral.sh/uv/install.sh | sh
• Install rustup: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
• Restart your shell to make sure cargo is available
• Install the other dependencies: ./mach bootstrap
• Build servoshell: ./mach build

Windows

• Download uv, choco, and rustup
  • Be sure to select Quick install via the Visual Studio Community installer
• In the Visual Studio Installer, ensure the following components are installed:
  • Windows 10/11 SDK (anything >= 10.0.19041.0) (Microsoft.VisualStudio.Component.Windows{10, 11}SDK.{>=19041})
  • MSVC v143 - VS 2022 C++ x64/x86 build tools (Latest) (Microsoft.VisualStudio.Component.VC.Tools.x86.x64)
  • C++ ATL for latest v143 build tools (x86 & x64) (Microsoft.VisualStudio.Component.VC.ATL)
• Restart your shell to make sure cargo is available
• Install the other dependencies: .\mach bootstrap
• Build servoshell: .\mach build

Android

• Ensure that the following environment variables are set:
  • ANDROID_SDK_ROOT
  • ANDROID_NDK_ROOT: $ANDROID_SDK_ROOT/ndk/28.2.13676358/ ANDROID_SDK_ROOT can be any directory (such as ~/android-sdk). All of the Android build dependencies will be installed there.
• Install the latest version of the Android command-line tools to $ANDROID_SDK_ROOT/cmdline-tools/latest.
• Run the following command to install the necessary components:

  sudo $ANDROID_SDK_ROOT/cmdline-tools/latest/bin/sdkmanager --install \
   "build-tools;34.0.0" \
   "emulator" \
   "ndk;28.2.13676358" \
   "platform-tools" \
   "platforms;android-33" \
   "system-images;android-33;google_apis;x86_64"
  

• Follow the instructions above for the platform you are building on

OpenHarmony

• Follow the instructions above for the platform you are building on to prepare the environment.
• Depending on the target distribution (e.g. HarmonyOS NEXT vs pure OpenHarmony) the build configuration will differ slightly.
• Ensure that the following environment variables are set
  • DEVECO_SDK_HOME (Required when targeting HarmonyOS NEXT)
  • OHOS_BASE_SDK_HOME (Required when targeting OpenHarmony)
  • OHOS_SDK_NATIVE (e.g. ${DEVECO_SDK_HOME}/default/openharmony/native or ${OHOS_BASE_SDK_HOME}/${API_VERSION}/native)
  • SERVO_OHOS_SIGNING_CONFIG: Path to json file containing a valid signing configuration for the demo app.
• Review the detailed instructions at [Building for OpenHarmony].
• The target distribution can be modified by passing --flavor=<default|harmonyos> to mach <build|package|install>.
