Cosmoner Container Registry vs OpenRegistry

Cosmoner Container Registry is a managed private registry backed by Amazon ECR for storing container images used by apps. Developers can push and pull images from a laptop or CI system with Docker and a Cosmoner API key. Images in a project registry appear in the Apps image deployment flow, where deployments authenticate without a pull secret. Scanning on push is enabled by default and checks images against known vulnerabilities. Images use AES256 encryption by default, with a customer KMS key available for repositories created afterward. Retention settings can keep a selected number of recent images and expire untagged images after a chosen number of days. Repositories are private by default; public repositories require a monthly egress cap and revert to private when it is reached. The product lists nine regions across North America, Europe, and Asia Pacific, and a registry’s region cannot be changed after creation. Uploads are not charged; egress, storage, and a registry fee are billed separately. The registry fee is $1 a month, prorated from creation; storage is $0.25 a month per GB, and egress is $0.15 a month per GB after the first 10 GB per organization per billing period.
