| Deployment | Self-hosted deployments support Docker, Podman, Kubernetes, and OpenShift, and can keep source code, signing identities, and build artifacts within the customer's network. | Prow runs in Kubernetes clusters, and the deployment guide says it should work on any Kubernetes distribution with no or minimal changes. |
| Integrations | Appcircle lists hundreds of ready workflow steps, including Fastlane, SonarQube, BrowserStack, Firebase App Distribution, and AWS Device Farm. | Prow integrates with GitHub and can also work with Gerrit, though Tide and Hook do not work with Gerrit. |
| Purpose | Its stated mission is to simplify and automate mobile development workflows for teams of all sizes. | Prow is a Kubernetes based CI/CD system for running jobs and automating GitHub workflows. |
| Security | Appcircle says source code is fetched only during builds, build agents are isolated temporary virtual machines, and repository access uses read-only tokens. | Hook validates incoming GitHub webhooks using configured HMAC credentials. |
| Support | Appcircle offers documentation and community support, while dedicated SLA support includes ticketing, security and legal assessment assistance, prioritized feature requests, and a dedicated customer success manager. | The project directs users to open a repository issue, contact the #prow Kubernetes Slack channel, or contact code owners. |
