The short version

  • Each has a real cost: 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.; Visual Studio community edition is free only for individual developers, classroom use, academic research and open-source contribution, not general commercial use

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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.

Visual Studio

  • Community edition is free only for individual developers, classroom use, academic research and open-source contribution, not general commercial use
  • Monthly subscriptions are $45 per user per month for Professional and $250 per user per month for Enterprise, and do not include perpetual use rights the way annual Standard subscriptions do
  • A standalone perpetually licensed Visual Studio Professional 2022 costs $499 as a one-time purchase, separate from the subscription tiers

Answered from the vendors’ own pages

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.

Visual Studio: What are the pricing differences between subscription types?

Standard subscriptions include access to more benefits, such as Azure dev/test pricing, monthly Azure individual credit, software and download access, services, training, and support. Monthly subscriptions offer flexibility but fewer benefits.

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.

Visual Studio: Are discounts available for startups?

There aren't any discounts available to start-ups, however an unlimited number of users within an organization can use Visual Studio Community for specific scenarios like open source work.

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.

Visual Studio: Who can use Visual Studio Community for free?

In non-enterprise organizations, up to five users can use it. Enterprise organizations (greater than 250 PCs or greater than $1M annual revenue) cannot use it beyond academic/open-source scenarios.

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.

Visual Studio: What's the renewal pricing structure?

Enterprise standard renews at $214.09/month (after initial $499.92); Professional at $66.59/month (after $99.99).

Source
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.
