The short version

  • Each has a real cost: Nx Cloud requires Nx workspace setup; integration limited to Nx build system; Sigstore the security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
  • They diverge on capability: Nx Cloud covers Nx Replay, Sigstore covers Fulcio.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Nx Cloud

  • Requires Nx workspace setup; integration limited to Nx build system
  • Free tier restricted to 5 contributors; larger teams require paid plans
  • Credits system adds complexity to cost prediction vs flat-rate competitors
  • Self-hosted Enterprise deployment requires significant operational overhead

Sigstore

  • The security model depends on somebody watching the log. The documentation states that compromise of an identity provider or of Fulcio itself is detectable only if third parties monitor the transparency log, the monitoring tool is a community-tier rather than core project, and almost no consumer runs one.
  • It is a 99.5 percent objective with no service level agreement, which permits several hours of downtime a month and offers no remedy. A pipeline that signs on every build has taken a hard dependency on a free service with no contract behind it.
  • Log scale is a live engineering problem rather than a theoretical one. The active shard holds billions of entries, the log has already been sharded twice, and sharding version 1 requires stopping traffic, which is why a replacement was built.
  • Ten-minute certificates make trust depend on log availability. Verifying an older signature relies on the log entry proving it was made inside that window, so a lost or unreachable entry can render a valid artifact unverifiable.
  • Migration debt is substantial and ongoing. Version 2 of the log is generally available but not the public default, the signing client has an announced breaking release ahead, some official clients lag the new log format, and a post-quantum migration is named as the next break after that.

Answered from the vendors’ own pages

Nx Cloud: What is included in the free Hobby plan?

The Hobby plan includes 50,000 monthly credits, support for 5 contributors, 10 concurrent CI connections, and basic analytics at no cost with no credit card required.

Source
Sigstore: Is the public instance really free?

Yes, with no contract and no paid tier. That is also the weakness: a 99.5 percent objective with no agreement, no remedy and support through Slack.

Nx Cloud: How are overages charged on the Team plan?

The Team plan starts at $29/month with included credits. Additional credits cost $5.50 per 10,000 credits, extra contributors cost $19 each, and additional CI connections cost $2.25 each.

Source
Sigstore: Has the public log moved to Rekor v2?

No. Version 2 reached general availability in October 2025 and self-hosters can use it, but the public instance still defaults to version 1 and the project has said it will for the foreseeable future.

Nx Cloud: Can Nx Cloud be self-hosted?

Yes, Enterprise customers can deploy Nx Cloud on-premises or on managed infrastructure to maintain full control over data and infrastructure.

Source
Sigstore: Does Sigstore make my dependencies safe?

No, and this is a category error worth avoiding. It tells you who published something. It has no knowledge of what the artifact contains or whether it is vulnerable.

Sigstore: What are the rate limits?

Not published. Only the 100KB cap per attestation upload is documented, so do not design a high-volume pipeline around assumed throughput.

Sigstore: Should we self-host it?

If a public record of every signature is unacceptable, or if a free service with no agreement cannot sit in your build path, then yes. Otherwise the public instance is what most projects use.
