The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: CitizenLab citizenLab has rebranded to Go Vocal and the product now sells under govocal.com; 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: CitizenLab covers Participatory Budgeting, 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.

CitizenLab

  • CitizenLab has rebranded to Go Vocal and the product now sells under govocal.com
  • No prices are published on the plans page; every tier requires scheduling a demo
  • The Essential plan allows only 1 active project and 1 admin seat, with no project manager seats
  • Standard is limited to 4 admin seats and 5 project manager seats, and Premium to 8 admin seats and 25 project manager seats
  • Standard restricts Sensemaking to Light, capped at 30 inputs; auto-insights require Premium
  • The integrated Konveio document annotation and Echo blended engagement methods are excluded from Standard and require Premium
  • Auto-translation on Premium is limited to 3 languages
  • Custom fonts and other premium styling options are Premium only
  • Priority support is Premium only
  • Plans are split by population band, with separate ladders for cities under and over 100K population

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

CitizenLab: How many projects can Essential tier teams manage?

The Essential tier is designed for teams starting small and is limited to 1 active project with 1 admin seat and no project manager seats.

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.

CitizenLab: How many projects can Standard and Premium tiers manage?

Both Standard and Premium tiers support unlimited projects. Standard includes 4 admin seats and 5 project manager seats, while Premium includes 8 admin seats and 25 project manager seats.

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.

CitizenLab: Does Enterprise tier have any user seat limits?

No, the Enterprise tier is designed for organizations aiming to embed engagement deeply within their infrastructure and includes unlimited admin seats and project managers.

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.

CitizenLab: What are the specific pricing amounts for each tier?

Specific pricing amounts are not disclosed on the plans page. The company directs interested organizations to talk to their team for personalized pricing offers.

Source
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.
