Last updated on Oct 7, 2026 You can accelerate Bazel builds with Incredibuild Linux. You do not need to change your source code or build scripts. Wrap your existing Bazel command with ib_console, as described in Executing Your Builds Using Incredibuild Linux.

​
Prerequisites

  • Incredibuild Linux is installed and your grid is available.
  • Your Bazel build already completes successfully without Incredibuild.
  • The Initiator meets the Minimum local cores for build setting in Agent Settings. Otherwise the build will not start. See Executing Your Builds Using Incredibuild Linux.

​
Default profile

The default profile at /opt/incredibuild/data/ib_profile.xml marks Bazel and related sandbox helpers (including linux-sandbox and similar wrappers) as intercepted. You do not need a custom profile for typical Bazel projects. If you require any profile customization, contact the Incredibuild Performance Engineering Team or Support.

​
Running a build

Run a Bazel build using the ib_console command. For example:
Set <N> to reflect your grid capacity. As with other Linux build tools, set the concurrency level about 20% higher than the total cores available in your Incredibuild grid. See Executing Your Builds Using Incredibuild Linux. It is recommended to use Build Avoidance flags such as --avoid-user or --avoid-shared when they apply to your workflow. See Build Avoidance.
