Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Skopeo
- Single-purpose: it neither builds nor runs images, so it is one tool in a chain rather than a solution
- Command syntax with transport prefixes such as docker:// is unusual and trips people up initially
- Documentation is sparse compared with the rest of the container ecosystem
Socket
- Team plan requires minimum 5-developer commitment, expensive for small teams
- Business plan $50/dev/month becomes costly for teams exceeding 20 members
- Enterprise pricing requires custom consultation with no transparent pricing
- Free plan limited to individual developers without team collaboration
- Reachability analysis improvement (90% false positive reduction) only on Enterprise

Answered from the vendors’ own pages
Skopeo: Is Skopeo free?
Yes, open source with no licence fee.
Socket: How many zero-day attacks does Socket detect?
Socket detects over 100 zero-day attacks weekly across JavaScript, Python, and Go ecosystems.
SourceSkopeo: Why copy images without pulling them?
A registry-to-registry copy avoids downloading and re-uploading gigabytes, which is faster and much cheaper on bandwidth in CI.
Socket: What is precomputed reachability analysis?
Socket's precomputed reachability analysis cuts CVE false positives by 60% automatically on Team plans, and up to 90% on Enterprise plans through function-level analysis.
SourceSkopeo: Can Skopeo run containers?
No. It only inspects, copies, signs and deletes images. Running them is Podman’s or Docker’s job.
Socket: Is there a discount for annual billing?
Yes. Socket offers a 20% discount for annual commitments across all subscription tiers.
