# Aspect Workflows

> Aspect Workflows gives Bazel a remote cache, the Build Results UI, remote execution, CI runners and selective delivery. Start free on Aspect Cloud, or run an isolated Aspect Enterprise deployment. The Aspect CLI and rulesets are free and open source.

**Aspect Workflows** is a remote cache, the Build Results UI, remote execution, CI runners and selective delivery for Bazel. With the free, open-source Aspect CLI and rulesets, it makes up the Aspect platform. Your pipelines keep calling `bazel`, and your BUILD files don't change.

It runs on one of two offerings: **Aspect Cloud**, Aspect's multi-tenant service, and **Aspect Enterprise**, an isolated deployment for your organization. [Choosing Aspect Cloud or Aspect Enterprise](/docs/aspect-workflows/platform/choosing) compares them side by side.

## Aspect Cloud

[Aspect Cloud](/docs/aspect-workflows/cloud/overview) is running in minutes: sign up, log in with the Aspect CLI, and point Bazel at it. There's nothing to provision.

* **A remote cache shared by CI and every developer.** Add it to the CI runners you already have with one [setup step](/docs/aspect-workflows/cloud/ci-setup).
* **The [Build Results UI](/docs/aspect-workflows/platform/features/webui)** for every invocation, from CI and local development. Logs stream while the build runs, flaky tests are separated from real failures, and JUnit cases are parsed out of large suites.
* **Free to start.** Aspect Cloud has a Free tier and a Team tier. See [pricing](/pricing).

## Aspect Enterprise

[Aspect Enterprise](/docs/aspect-workflows/enterprise/overview) is an isolated deployment for your organization, with infrastructure and data no other customer shares. CI runners and remote execution are available on it today, so it's for teams that need them now, or whose policy requires isolation. It's [hosted by Aspect](/docs/aspect-workflows/enterprise/hosted/overview), [self-hosted](/docs/aspect-workflows/enterprise/self-hosted) in your AWS account or GCP project, including air-gapped and GovCloud, or on-prem (coming soon), deployed with a Helm chart on your own hardware.

Every deployment includes every Aspect Workflows capability. Also available: SSO, your own identity provider in place of Aspect sign-in, SCIM provisioning, private endpoints, VPC peering, endpoints on your own DNS domain, remote execution workers on your own hardware, and a choice of who operates it.

[Talk to us](/contact) about a 30-day [trial of Aspect Enterprise](/docs/aspect-workflows/enterprise/evaluation/greening) on your own repository.

## Free and open source

The [Aspect CLI](/docs/cli/overview) connects your builds to Aspect Workflows and adds status checks, PR comments and inline lint findings on GitHub and GitLab. It runs formatting, linting, BUILD file generation and delivery as tasks that behave the same on a laptop and in CI. Aspect also maintains [rules\_py, rules\_js, rules\_ts and rules\_lint](/docs/bazel). Both are free, with or without Aspect Workflows.

## Security

Aspect is SOC 2 Type 2 certified. [Security and data handling](/docs/aspect-workflows/platform/security) covers what Aspect Cloud and an Aspect Enterprise deployment store, where, and who at Aspect can reach it. The [security overview](/security-overview) covers compliance.
