Fast builds

Fast builds

Optimize your Bazel configuration so you can spend less time waiting on CI and more time shipping code to production.

Reduced compute costs

Reduced compute costs

Minimize cloud costs with self-hosted, auto-scaling CI runners that leverage Bazel’s built-in incrementally

Remote cache & execution

Aspect Workflows remote cache & remote execution clusters are self-hosted on your AWS or GCP cloud account.

Comprehensive Solution

Features to support each part of the development process, so you can focus on delivering exceptional products.

“Aspect Workflows has made Bazel an order of magnitude easier to deal with and also more valuable."

Jimmy Tanner, Software Engineer

"We saw significant improvements in build consistency. Optimized dependencies led to fast and cost-effective AI training and inference cycles."

Decreased wait time

“If we showed this to all the engineers at Sourcegraph there would be a mutiny if we didn't buy it.

3.7x

More sub-2min builds

2.4x

Speedup of median build & test

40%

Reduced compute costs (despite higher usage)

“We went from having significant limits in CI and tools to where the limits are now just due to our code.”

Neal Norwitz, Software Engineer

10x

Faster no-op build from 11 min to 1 min

2-3x

Speedup of typical build & test

Streamline development across your organization while using your existing development workflows.

Aspect’s multi-language developer platform scales with your organization as you grow.

Features

Our platform delivers fast, scalable, developer workflows and infrastructure for Bazel out of the box, so your team can build the future, faster.

Aspect’s Web UI

Highlight critical information needed to resolve your build failures, so you stay in the flow.

GitHub Code Review App

Marvin delivers build and test results directly to pull requests, ensuring you receive immediate notifications when a build begins to fail.

CI Runners

Aspect Workflows configures CI to trust that Bazel is correct, ensuring builds are fast and compute costs are reduced.

Managed Buildbarn

Aspect leverages Buildbarn’s proven remote cache and execution—trusted by Apple developers—to boost Bazel performance.

Build File Generation

Write extensions in Starlark. The same language you use to configure Bazel! Tree-sitter grammars included.

Observability

We've added distributed tracing all the way from your CI pipeline down to individual actions, along with metrics that power your dashboard and alerting.

Why Teams Choose Aspect

Aspect Development seamlessly steered our build system transition from a jumble of various technologies to solely Bazel. The efficiency with which they completed a task that would have otherwise taken us many months is a testament to their unparalleled expertise. Above all, collaborating with every member of the Aspect Development team was an absolute pleasure.

As a Bazel monorepo, our frontend builds have always been difficult to understand and reason about. With Aspect's congenial, guided assistance, we've brought our production and local development build pipelines closer to each other. We've also brought Bazel's NPM management into a new and more hermetic structure, and we’ve unlocked future improvement paths via SWC and esbuild integrations.

FullStory

I cannot imagine building and testing Angular without Bazel. It's been a life-changer for us and enabled us to scale and iterate in ways that we couldn't have accomplished otherwise without sacrificing correctness and ultimately reliability of our CI infrastructure. Alex and Greg were key to our onboarding. I have a lot of respect for their unrelenting focus on increasing developer productivity at scale.

TL of Angular

We felt intimidated by Bazel at first, but Aspect accompanied us in implementing it in our TypeScript monorepo. We've drastically reduced our overall CI pipeline time from an hour to 7 minutes

CTO of WeMaintain

The team helped us to make improvements to local development: no more random bash scripts that you forget to run, incremental builds reduced to seconds from minutes.
