The short version

  • Only Sigstore has a free tier, so it costs nothing to try first.
  • 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.; Xlinesoft the purchase includes one year of support and upgrades only; after that, newer versions require a paid upgrade.
  • They diverge on capability: Sigstore covers Fulcio, Xlinesoft covers Database to web application.
  • Prices and features above were last checked on 12 November 2026.

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.

Xlinesoft

  • The purchase includes one year of support and upgrades only; after that, newer versions require a paid upgrade.
  • Multiple database connections, REST API connections and single sign-on through Active Directory, Okta or SAML are Enterprise-only, which raises the price from $599 to $999 per developer.
  • Self-hosted only. Hosting, database administration, backups, runtime updates and access-control configuration remain the customer's job, as Xlinesoft's own product facts page states.
  • Applications built on Microsoft Access require a Windows web server.
  • PHPRunner and ASPRunner.NET are separate products with separate licences, so moving a project between PHP and .NET is not covered by one purchase.

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.

Xlinesoft: How much does PHPRunner cost?

PHPRunner Professional is $599, Enterprise Edition is $999 and MultiDev Edition, which includes three Enterprise licences, is $3,599. Professional and Enterprise prices are per developer, and each purchase includes one year of email support and free upgrades.

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.

Xlinesoft: Which databases does PHPRunner support?

MySQL, MariaDB, Microsoft SQL Server, PostgreSQL, Oracle, Microsoft Access, IBM DB2, Informix, SQLite and ODBC-compatible databases. Using multiple database connections in one project is an Enterprise Edition feature.

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.

Xlinesoft: Is there a free trial?

Yes. PHPRunner can be downloaded and evaluated for 21 days, and public live demos show the generated applications, with add, edit and delete disabled.

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.

Xlinesoft: Where do PHPRunner applications run?

On your own web server. The documented options are Apache and Microsoft IIS with a compatible PHP runtime and database extensions, and a built-in web server is available for local testing. The development application itself runs on Windows, macOS and Linux.

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.

Xlinesoft: What does the Enterprise Edition add?

Multiple database and REST API connections, data encryption, and enterprise authentication including Active Directory, Okta, Azure AD, OpenID and SAML, on top of all Professional features.

Source
Xlinesoft: What is ASPRunner.NET?

Xlinesoft's equivalent builder for ASP.NET. It generates database-driven ASP.NET web applications with the same kind of forms, reports, charts, permissions and Page Designer, and is sold separately from $599.
