GitHub Container Registry
Pros
- + Free storage and bandwidth for public images with anonymous pulls — strongest OSS distribution offer
- + Images live with the code: one account, one permission model, GITHUB_TOKEN in Actions
- + OCI-compliant (Docker V2 manifests, foreign layers), internal visibility and fine-grained package permissions
- + Container image storage currently free even for private images, with a one-month notice policy before changes
- + Spending limits available to cap overage; metered billing beyond plan quotas
Cons
- - Private plan quotas are small (500 MB on Free) and shared with GitHub Actions artifacts
- - Free private container storage is a policy, not a contract — changeable with one month's notice
- - No published SLA or regional placement for ghcr.io
- - Retention and promotion tooling lag purpose-built registries like Harbor or Artifactory
Portainer
Pros
- + Business Edition free forever for 3 nodes with the complete feature set; Community Edition fully open source
- + Published per-node pricing — rare transparency with no contact-sales wall before Starter and Scale
- + One license covers Docker, Swarm, Kubernetes, and Podman environments together
- + Strong governance: RBAC, SSO/LDAP, audit logs, GitOps, fleet policies with drift remediation
- + Edge capability is real: offline-first, air-gap capable, industrial fleets at scale
Cons
- - Self-hosted only — you own the servers and the underlying platform problems
- - Starter's 16 vCPU-per-node cap and community-only support push upgrades sooner than expected
- - Cost scales with both node count and node size; Enterprise is quote-only
- - A UI over Kubernetes does not remove deep Kubernetes debugging when things break
