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.
Nullstone
Nullstone is a developer platform for launching and managing applications on cloud providers such as AWS. It can run workloads as containers, serverless apps, static sites, or applications on servers. Preview environments can be created from a pull request or branch and removed after review or testing. Teams provision infrastructure with Terraform modules they can fork, customize, or create from scratch. Nullstone launches infrastructure in customers’ cloud accounts and says it does not access their data; secrets remain in that account in a vault such as AWS Secrets Manager. Its security information lists SOC 2 Type II certification and role-based access controls. Listed integrations include Datadog, NewRelic, SumoLogic, CircleCI, Jenkins, and GitHub Actions. The open-source CLI supports deployments, infrastructure provisioning, data retrieval, and module management on macOS, Windows, and Linux. The Individual plan is free at free; Startup costs $50 a month and includes two users, two environments, and 30 deploys per week. The SaaS service is hosted only and cannot be independently run or installed by customers.
