PRIVATE REGISTRY COMPARISON
AWS CodeArtifact is a managed package repository integrated with AWS identity and infrastructure. PrivateNPM offers hosted npm, PyPI and Files registries with dedicated publisher and recipient credentials. Compare AWS integration with the experience of the people installing your packages.
Reviewed by the PrivateNPM team. This is a vendor comparison; official sources and assumptions are linked below.
THE DECISION
CodeArtifact is a strong candidate for teams already managing build identities and package access in AWS. PrivateNPM is worth testing when customers need to install packages without adopting your AWS authentication workflow.
Your package consumers include external customers, and you want separate download credentials and package grants rather than asking them to use an AWS-oriented login process. You want published organization plans for supported formats.
Your build system already relies on AWS identities, regions and services. CodeArtifact's managed infrastructure and integration with that environment may be more valuable than introducing another account and registry service.
CAPABILITIES AND TRADEOFFS
| Requirement | PrivateNPM | AWS CodeArtifact |
|---|---|---|
| Identity | Publisher keys, supported CI OIDC and separate recipient keys. | AWS credentials and CodeArtifact authorization tokens. |
| Token lifecycle | Manage recipient keys independently of publishing credentials. | npm login authorization defaults to 12 hours; plan periodic refresh. |
| Billing inputs | Plan allowances and download overage, subject to published limits. | Storage, requests and chargeable transfer; inspect regional rates and exemptions. |
| Best evaluation context | Customer delivery across supported registry formats. | Package workflows that benefit from AWS infrastructure and identity integration. |
PrivateNPM features Plan limits and pricing Competitor documentation
ESTIMATE YOUR MONTH
Enter decimal GB (1 TB = 1,000 GB), human publisher seats and hosted packages across formats. Amounts are USD per month before tax. Customers using download keys are not publisher seats.
PrivateNPM estimates use the published monthly billing catalog, whole GB of excess transfer and the default overage cap of one monthly plan price. The first overage month is waived; these are ongoing-month examples. Annual billing, trial rules and a changed spend cap affect the bill. Registry count, download-key count and other feature requirements are not modeled: check all plan limits.
WORKED EXAMPLES
Compare CI inside AWS with a customer's install outside AWS. Record the region, request volume, transfer destination and token refresh method. AWS documents a default 12-hour authorization period after login, so test renewal as well as the first successful install.
These are illustrative monthly workloads, not customer results or vendor benchmarks. Each PrivateNPM estimate selects the lowest-priced plan eligible for the shown storage, seat and package counts. Other plan limits still apply.
10 GB stored · 100 GB downloaded · 5 seats · 20 packages.
PrivateNPM: $29/month. Growth · monthly billing, default overage cap
AWS CodeArtifact: evaluate this workload using the provider's pricing model and your additional requirements. No competitor bill is estimated.

MIGRATION CHECKLIST
Start with one package and one consumer. Keep the existing service available until you have verified publishing, allowed installs, denied access and rollback. Package bytes can be copied; identities, permissions and audit history require separate planning.
Use a publisher key to publish, then a read-only download key in a clean consumer project. Confirm that an allowed package installs, an ungranted package is denied and revocation blocks new downloads after the authorization cache expires. Already downloaded content cannot be revoked from a customer's disk.
Follow the publish-and-install quickstart, then configure the registry route and host-specific credential. For CI, use the trusted publishing guide. These are PrivateNPM walkthroughs; the checklist above is a migration plan, not a claim that every provider has been tested end to end.
Preserve an inventory of required versions, integrity values and dist-tags. Use package-manager commands to update lockfiles and inspect resolved URLs. Do not delete the source packages or revoke the old credentials until consumers have switched and you can restore the previous configuration.
CodeArtifact pricing depends on requests and transfer paths as well as storage, with regional and free-tier considerations. Showing a precise figure from storage and downloads alone could misrepresent the bill.
AWS documents a default 12-hour authorization period after login and periodic renewal. Verify the lifetime and renewal method used by your specific client and CI workflow.
