The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: ArchiveSocial coverage depends entirely on third party platform APIs, so when a network restricts or reprices its API the archive's completeness changes for reasons the vendor does not control.; 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: ArchiveSocial covers Continuous capture, 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.

ArchiveSocial

  • Coverage depends entirely on third party platform APIs, so when a network restricts or reprices its API the archive's completeness changes for reasons the vendor does not control.
  • Pricing scales with the number of archived accounts, so an agency where every department runs its own page pays repeatedly for the same compliance obligation.
  • It archives rather than governs, so it will faithfully preserve a policy violation without preventing it, and agencies still need social media policy and training.
  • Since the 2021 CivicPlus acquisition the product is part of a municipal suite, so buyers avoiding that vendor for other reasons are still buying from them.
  • The value is entirely insurance shaped, which makes it a perennial target during budget cuts right up until the first records request it would have answered.

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

ArchiveSocial: Why not just export data from the platforms?

Platform exports do not reliably capture deleted or edited content and carry no chain of custody, which is what makes an archive usable as evidence.

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.

ArchiveSocial: Are public comments on our posts records?

In many United States jurisdictions yes, and deleted comments have been the subject of litigation against agencies.

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.

ArchiveSocial: Who owns ArchiveSocial?

CivicPlus, which acquired it in 2021 and sells it alongside its municipal website and communications products.

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.

ArchiveSocial: How is it priced?

By archived accounts, quoted rather than published. Comparable agency contracts are public records.

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.
