| Architecture | Config Sync includes hosted components running in Google Cloud and open source components running on the GKE cluster. | The control plane is a web service exposing UI, API endpoints and metadata storage, while piped is a lightweight agent that runs plugins. |
| Self-hosting | The public repository documents installation of OSS Config Sync directly on Kubernetes, while GKE and Anthos users can install through Google Cloud GUI or CLI. | Operators can install the control plane themselves and run piped as a Kubernetes pod, ECS container, serverless function or local process. |
| Support | Google Cloud offers support packages including 24/7 coverage, phone support, and access to a technical support manager. | The project directs users to documentation, GitHub issues and discussions, and the CNCF Slack #pipecd channel for help. |
| What it does | Config Sync automates synchronization of Kubernetes configurations and policies from a central source of truth to multiple clusters. | PipeCD is a GitOps continuous-delivery platform intended to give one deployment and operations interface across applications and platforms. |

In their own words
Google Config Sync
Google Config Sync keeps configuration and policies aligned across Kubernetes clusters by monitoring a source of truth and reconciling cluster state. It can sync files from Git repositories, OCI images and Helm charts, and apply Policy Controller constraints to registered and connected clusters. Namespace management supports multi-tenancy through namespace-scoped policies such as RBAC roles. Config Sync supports Autopilot and Standard GKE clusters, plus GKE-attached clusters including EKS and AKS. Clusters must be registered to a fleet before the service can be enabled. Its architecture combines hosted Google Cloud components with open-source components running on GKE. For OCI repositories, it can integrate with an admission webhook signature verification server to help ensure only trusted images are used. Config Sync is included with Google Kubernetes Engine at free, subject to a GKE-supported cluster version and fleet registration. It runs only on x86-based nodes, not Arm nodes. The drift-prevention admission webhook can use high memory and cause out-of-memory errors in clusters with many custom resources.
PipeCD
PipeCD is a self-hosted continuous delivery platform that coordinates deployments through Git pull requests. Its shared deployment interface supports Kubernetes, Terraform, GCP Cloud Run, AWS Lambda, AWS ECS and other targets, while plugins let teams add custom applications or platforms. PipeCD says deployment setup needs a pipeline definition and application manifests, without changes to CRDs or application manifests. Built-in analysis assesses deployment impact with metrics, logs and emitted requests; the platform can roll back after analysis or pipeline-stage failures, detect configuration drift and launch deployments from defined events. Its UI presents deployment pipelines, per-deployment logs, live application state and delivery-performance insights. A centralized Control Plane works with piped agents that run deployments using plugin binaries. Security features include single sign-on and role-based access control, and credentials stay outside the Control Plane. PipeCD is open source under Apache 2.0 and costs nothing. For private Git repositories, piped needs a private SSH key and its corresponding public key added to the repository.
