What is Aspect Build?
Aspect Build provides a developer productivity platform and expert services designed to reduce the time and complexity of operating Bazel at scale. It targets organizations and development teams using or looking to adopt Bazel for multi-language monorepos, offering solutions to common challenges like configuration, performance optimization, and developer enablement. The platform streamlines Bazel workflows, integrates with existing CI/CD tools, and provides options for both Aspect-hosted and self-hosted deployments to meet specific security, data control, and cost requirements.
The core offering, Aspect Workflows, automates Bazel's "busy work" and enhances its speed through optimized configurations, remote caching, and remote execution for massively parallelized workloads. It also includes tools for build file generation, GitHub code review integration, and a web UI for triaging build failures. Complementing the platform, Aspect offers consulting, training, and support services, providing direct access to Bazel experts to guide adoption, resolve issues, and upskill development teams.

Aspect Build FAQ
How does Aspect Workflows improve Bazel's performance beyond its native capabilities?
Aspect Workflows enhances Bazel's performance by optimizing configuration files, toolchains, and external dependencies. It provides remote caching to reuse build artifacts and remote execution to parallelize workloads across a distributed system, significantly speeding up build times and reducing resource consumption.
What is the Aspect Extension Language (AXL) and how does it benefit Bazel users?
AXL allows users to extend tasks anywhere within their Bazel environment. It provides a powerful mechanism to customize and automate specific build, test, or deployment steps, enabling greater flexibility and integration with unique development workflows that might not be directly supported by standard Bazel rules.
Can Aspect Workflows be deployed in an air-gapped network environment?
Yes, Aspect Workflows offers self-hosted deployment options, including the ability to run in an air-gapped network. This provides enhanced security and data control for organizations with strict compliance requirements, ensuring that build data and processes remain entirely within their private infrastructure.
How does the GitHub Code Review integration with Marvin assist developers?
The GitHub Code Review integration, powered by Marvin, automatically tests code quality and provides live build result updates directly in GitHub PR comments and Buildkite annotations. It also surfaces lint results, format checks, and code generation checks as suggested fixes, streamlining the code review process and improving code quality.
What level of customization is available for CI Runners within Aspect Workflows?
Aspect Workflows' CI Runners offer extensive customization, including autoscaling persistent runners, pre-warming of new instances, and the ability to define custom machine types and images per runner group. It also supports bare-metal execution, Docker-in-Docker actions, and FUSE mount to remote cache, allowing for highly optimized and tailored CI/CD environments.
What is the difference between Aspect-hosted and self-hosted deployment options for Aspect Workflows?
Aspect-hosted deployment means Aspect manages the infrastructure for your Bazel workflows. Self-hosted options allow you to deploy Aspect Workflows on your own cloud infrastructure or on-premise. Self-hosting provides greater control over security, data, and costs, and enables low-latency, high-bandwidth integrations, which is crucial for organizations with specific compliance or performance needs.
