The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mark43 no published pricing on homepage; sales contact required for all cost details; 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: Mark43 covers Computer-Aided Dispatch, 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.

Mark43

  • No published pricing on homepage; sales contact required for all cost details
  • Only reference to pricing is 'early bird pricing' for 2027 conference registration
  • No transparent pricing structure visible for public evaluation

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

Mark43: Does Mark43 publish pricing online?

No, Mark43 pricing is not published on the public website. The only pricing reference is early bird conference registration. Prospective customers must contact Mark43 through 'Book A Demo' or 'Let's Connect' for pricing consultation.

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.

Mark43: What payment methods or financing options does Mark43 offer?

No information about payment methods or financing options is disclosed on the public homepage. Pricing and payment details are handled through direct sales consultations.

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.

Mark43: Are there volume discounts or specialized pricing for different agency sizes?

Mark43 website does not disclose any volume pricing, per-user costs, or specialized rates for agencies of different sizes. All pricing inquiries require direct contact with sales team.

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.
