The short version

  • Each has a real cost: Descope free tier capped at 7,500 MAU; Pro tier at 10,000 MAU, Growth tier at 25,000 MAU, forcing migration to Enterprise for larger organisations; 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.

Where each one falls short

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

Descope

  • Free tier capped at 7,500 MAU; Pro tier at 10,000 MAU, Growth tier at 25,000 MAU, forcing migration to Enterprise for larger organisations
  • HIPAA compliance only available in Growth tier ($799/mo) and above; not included in lower-priced plans
  • No-code UI builder provides pre-built flows but still requires custom frontend development for fully-branded authentication experiences
  • All paid tiers billed annually; no monthly billing option for commitment-free flexibility
  • Bot protection features available only in Growth tier and above

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

Descope: Can I build custom authentication flows without code?

Yes. Descope's drag-and-drop workflow interface allows you to construct and modify signup, login, MFA and SSO flows without code changes.

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.

Descope: Does Descope support AI agent authentication?

Yes. Descope supports building identity journeys for AI agents and MCP servers, including scoped OAuth tokens and delegation chains.

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.

Descope: Is Descope HIPAA compliant?

HIPAA compliance is available in Growth tier and above, starting at $799/month.

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.
