The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: mySidewalk it produces analysis and presentation rather than operational change, so the value has to be re argued at every renewal against services with more visible outputs.; 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: mySidewalk covers Prewired federal datasets, 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.

mySidewalk

  • It produces analysis and presentation rather than operational change, so the value has to be re argued at every renewal against services with more visible outputs.
  • Budget frequently comes from a grant, which means the subscription is exposed when the grant cycle ends rather than being protected as core infrastructure.
  • The prewired datasets are American, so the platform has effectively no value outside United States federal statistical sources.
  • Analytical depth is bounded by what the platform exposes, so an agency with a genuine analyst will hit the ceiling and move to a statistical environment.
  • Small area estimates remain small area estimates, and presenting them as polished dashboards can lend unwarranted confidence to figures whose error bars overlap.

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

mySidewalk: What problem does it actually solve?

Correct use of American Community Survey and federal health data for small geographies, which is difficult and is usually held by one person in an agency.

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.

mySidewalk: Is it useful outside the United States?

No. Its value is the maintained pipeline into US federal statistical datasets.

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.

mySidewalk: Who buys it?

Mostly public health departments and city planning or performance teams, often funded from a grant that requires the evidence it produces.

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.

mySidewalk: Can we see comparable contract values?

Yes. Agency contracts are public records and appear in council and health board agenda materials.

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.
