What is Bazel?

Discover the power of Bazel, an open-source, multi-language build tool designed by Google to revolutionize development processes. By leveraging Bazel, developers can experience significant time savings through faster and reproducible builds and tests.

Bazel operates by intelligently caching and distributing builds, enabling incremental and efficient development workflows. When developers make changes to their code and initiate a build or test, Bazel taps into its cache of previous builds. It selectively rebuilds and tests only the specific changes made, eliminating unnecessary repetitions and drastically reducing build and test times.

At Aspect, we take pride in being an active contributor to the Bazel community.

Multi platform


Build binaries and deployable packages for multiple platforms.


Work with multiple user bases and repositories, or a huge monorepo. Bazel handles codebases of any size, and it helps scale your Continuous Integration system.


Extend Bazel to support any other language or framework.

Fast and reliable

Get fast, incremental builds by rebuilding only what's necessary.

Remote Execution

Bazel also allows for remote execution, which distributes the build to remote servers, further speeding up build & test.

Why Use Bazel?

Bazel maximizes developer productivity and helps your team deliver more reliable builds. When developers can iterate faster and test more frequently, they create more stable software.

How does Bazel work?

When running a build or a test, Bazel does the following:

1. Loads

Loads the BUILD files relevant to the target.

2. Analyzes

Analyzes the inputs, applies the specified build rules, and produces an action graph.

3. Executes

Executes the build actions on the inputs until the final build outputs are produced.

4. Reuses

Bazel can identify and reuse cached artifacts and only rebuild what’s changed.

Who uses Bazel?

Bazel is widely adopted by companies seeking to optimize their build and test workflows.
