aspect CLI is a drop-in replacement for the
bazel CLI that comes with Bazel.
Why Aspect CLI
Every organization has a different engineering culture and developer stack.
Bazel was designed for Google's workflows, not yours.
Many companies have found they have to write a wrapper around Bazel.
This starts out as a small need to shim something in the developer workflow, and is often an
untested Bash script living in
/tools/bazel which Bazelisk understands as a wrapper script.
Over time, the wrapper accumulates more code, and is a constant source of developer distress.

On MacOS, you can run
% brew install aspect-build/aspect/aspect
This installs the
aspect command and also links it to
bazel, just like the bazelisk installer does.
We plan to have a standard "core" homebrew formula so this will just be
brew install aspectin the future.
Bazelisk (MacOS / Linux / Windows)
On any platform, so long as you already have bazelisk installed, you can have bazelisk
install the Aspect CLI just like it can install the standard Bazel CLI.
Add this to your
.bazeliskrc in your project folder to install Aspect for all developers:
From the release you wish to use: https://github.com/aspect-build/aspect-cli/releases copy the
.bazeliskrc file to install Aspect for all developers in this repository.
Note that in all cases, the
.bazelversion file continues to indicate which version of the
Bazel tool is fetched and run beneath the wrapper.
Manual (MacOS / Linux / Windows)
On any platform, you can download the
aspect binary for your platform on our
Releases page and add it to your
Note, if you manually install for MacOS, you can bypass the "Unknown Developer" dialog by running
xattr -c $(which aspect) before launching
aspect help to see the available commands.
Some are the standard ones you know from Bazel, and others are new, such as
Write a plugin
Aspect's plugin system allows you to fit Bazel into your team's development process, with custom commands, behaviors, and integrations.
A plugin is any program (written in any language) that serves our gRPC protocol. The easiest way to get started is to clone our starter template repo.
See the Plugin Documentation for more information on how to write a plugin.
