Aspect Workflows is a turn-key Bazel CI/CD system that works with your existing CI provider

Experience the 10x performance benefit of Bazel

Why Aspect Workflows?

Fast builds

Optimize your Bazel configuration with fast warming, auto-scaling CI workers, a horizontally scaling remote cache and auto-scaling remote build executors so you can spend less time waiting on CI and more time shipping code to production.

Monitoring & alerts

Monitor your build metrics over time & get alerted immediately when there is a build or test breakage on main or a performance regression to your build lands.

Reduced compute costs

Minimize cloud costs with auto-scaling CI workers that leverage Bazel’s built-in incrementally.

Less maintenance

Aspect Workflows is available as a fully-managed offering. We operate the services, tune infrastructure configurations, and ensure CI stays fast and cloud costs are minimized.

Most CI platforms are based on the premise that the build system is incorrect: incremental rebuilds can produce stale results, so they are all designed around clean, cold workers that re-do all the build and test work.

Bazel should be hosted the opposite way: re-build and re-test work can be minimized by leveraging Bazel’s built-in incrementally, and correctness is guaranteed.

Making Bazel fast

Check icon

Configure Bazel with CI specific flags

Check icon

Operate a horizontally scalable remote cache service

Check icon

Detect anomalies to know when code changes regress performance

Detect and report on non-determinism that causes cache misses

Coming soon

Parallelize your build by running build actions on auto-scaling remote executors with remote build execution

Coming soon

Elastic pool of CI workers

Check icon

Reduce datacenter costs by scaling down unneeded replicas off-peak

Reduce developer queue times by scaling up in anticipation of peak load.

Coming soon

Engagement model

Check icon

Aspect engineers deploy the infrastructure, either in our Cloud account or yours

Check icon

Aspect engineers are on-call for the service under our SLA

Warm CI workers

Avoid slow builds during scale-up periods when a developer’s request is dispatched to a fresh worker that has no local cache.

Check icon

Ensure that Bazel repository cache is persisted across machines

Check icon

Prevent analysis cache discards

Check icon

Populate local cache from remote cache before accepting user requests

Check icon

Execute Bazel repository rules before accepting user requests

Affectedness

Prevent changes in one project from negatively affecting build and test times in another by only building and testing the exact set of targets affected in each change set.

Build and test only the subset of targets that are affected by files modified in change sets

Coming soon

Workflows improves on current solutions which are very incorrect or slow

Coming soon

Formatting and linting

Check icon

Ensure that formatters were run and fail quickly, with a developer experience that guarantees quick repair

Ensure that linters run and can report warnings back to code review tool

Coming soon

Keeping main green

Provide a Buildcop service which ensures that an oncall engineer is alerted and can easily and quickly repair any breakage

Coming soon

Selective Delivery

Check icon

Determine which deterministic build outputs differ from previous green builds

Coming soon
Check icon

Re-build changed artifacts with version stamping enabled

Coming soon
Check icon

Publish these artifacts to external storage such as container registry or cloud storage buckets

Coming soon
Check icon

Ensure that PR/diff requests don’t have permission to push artifacts
