The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • Each has a real cost: DocuWare complex setup requiring significant IT effort before full functionality is achieved; 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: DocuWare covers Document Storage, 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.

DocuWare

  • Complex setup requiring significant IT effort before full functionality is achieved
  • Limited user interface customization restricting tailored workflows and branding
  • Performance slowdowns when processing large document volumes or handling many simultaneous users
  • Search requires exact matches and is case-sensitive, limiting usability
  • Limited offline access with mobile app offering reduced functionality
  • Integration challenges with major ERP platforms
  • Steep initial investment, particularly for migrating older systems

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

DocuWare: Is DocuWare available as cloud or on-premises?

DocuWare is available as both a cloud-based SaaS solution and as an on-premises deployment option.

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.

DocuWare: What platforms does DocuWare support?

DocuWare is available as a web-based platform accessible via browser, with mobile apps available on iOS and Android.

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.

DocuWare: Does DocuWare offer offline access?

DocuWare has limited offline access capabilities. The mobile app offers fewer features compared to the desktop version.

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.
