Brave Core
Brave Core is a set of changes, APIs, and scripts used for customizing Chromium
to make the Brave browser. Please also check
https://github.com/brave/brave-browser which only holds the issues, releases and
the wiki.
Overview
This repository holds the build tools needed to build the Brave desktop browser
for all platforms. In particular, it fetches and syncs code from the projects
defined in package.json and src/brave/DEPS:
- Chromium
- Fetches code via
depot_tools.
- Sets the branch for Chromium (ex: 65.0.3325.181).
- brave-core
- Mounted at
src/brave.
- Maintains patches for 3rd party Chromium code.
- adblock-rust

Install prerequisites
Follow the instructions for your platform:
Clone and initialize
Once you have the prerequisites installed, you can get the code and initialize
the build environment.
Clone the repo. brave-core must be checked out into ./src/brave within a
pre-existing project folder:
git clone [email protected]:brave/brave-core.git path-to-your-project-folder/src/brave
cd path-to-your-project-folder/src/brave
Initialize the build environment. This step will download the Chromium
source, which has a large history (10's of gigabytes of data). This might take a
really long time to finish depending on internet speed.
# Most builds:
pnpm run init
# Android builds (replace `arm` with whichever CPU type you want to build for):
pnpm run init --target_os=android --target_arch=arm
# iOS builds:
pnpm run init --target_os=ios
Additional config needed to build are documented at
https://github.com/brave/brave-browser/wiki/Build-configuration
Internal developers can find more information at
https://github.com/brave/internal/wiki/Build-configuration
Build Brave
The default build type is component.
# start the component build compile
pnpm run build
To do a release build:
# start the release compile
pnpm run build Release
brave-core based android builds should use
pnpm run build --target_os=android --target_arch=arm
brave-core based iOS builds should use the Xcode project found in
ios/brave-ios/App. You can open this project directly or run
pnpm run ios_bootstrap --open_xcodeproj to have it opened in Xcode. See the
iOS Developer Environment
for more information on iOS builds.
Build Configurations
Running a release build with pnpm run build Release can be very slow and use a
lot of RAM, especially on Linux with the Gold LLVM plugin.
To run a statically linked build (takes longer to build, but starts faster):
pnpm run build Static
To run a debug build (Component build with is_debug=true):
pnpm run build Debug
NOTE: the build will take a while to complete. Depending on your processor and
memory, it could potentially take a few hours.
Run Brave
To start the build:
pnpm start [Release|Component|Static|Debug]
Update Brave
pnpm run sync [--force] [--init] [--create] [brave_core_ref]
This will attempt to stash your local changes in brave-core, but it's safer to
commit local changes before running this
pnpm run sync will (depending on the below flags):
- 📥 Update sub-projects (chromium, brave-core) to latest commit of a git ref
(e.g. tag or branch)
- 🤕 Apply patches
- 🔄 Update gclient DEPS dependencies
- ⏩ Run hooks
