Once you have the prerequisites installed, you can get the code and initialize the build environment.
git clone [email protected]:brave/brave-browser.git cd brave-browser npm install # this takes 30-45 minutes to run # the Chromium source is downloaded, which has a large history npm run init
brave-core based android builds should use
npm run init -- --target_os=android --target_arch=arm (or whichever CPU type you want to build for)
You can also set the target_os and target_arch for init and build using:
npm config set target_os android npm config set target_arch arm
The default build type is component.
# start the component build compile npm run build
To do a release build:
# start the release compile npm run build Release
brave-core based android builds should use
npm run build -- --target_os=android --target_arch=arm or set the npm config variables as specified above for
Running a release build with
npm 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):
npm run build -- Static
To run a debug build (Component build with is_debug=true):
npm run build -- Debug
Brave staff may also want to try Goma for faster builds.
To start the build:
npm start [Release|Component|Static|Debug]
npm 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
npm run sync will (depending on the below flags):

||updates chromium if needed and re-applies patches. If the chromium version did not change, it will only re-apply patches that have changed. Will update child dependencies only if any project needed updating during this script run.
**Use this if you want the script to manage keeping you up to date instead of pulling or switching branches manually. **
||updates both Chromium and brave-core to the latest remote commit for the current brave-core branch and the Chromium ref specified in brave-browser/package.json (e.g.
**Use this if you're having trouble and want to force the branches back to a known state. **

||Will not update the chromium version when applicable. Useful if you want to avoid a minor update when not ready for the larger build time a chromium update may result in. A warning will be output about the current code state expecting a different chromium version. Your build may fail as a result.|
npm run sync brave_core_ref to checkout the specified brave-core ref and update all dependent repos including chromium if needed.
