The short version

  • Each has a real cost: Stytch free tier limited to 10,000 monthly active users; scaling beyond this requires custom pricing negotiation; Syft lockfile parsing can drop packages silently. An open issue filed in August 2026 reports the yarn v1 cataloguer returning 118 of 745 packages with no error raised, which means a complete bill of materials and an 84 percent incomplete one look identical to the caller.

Where each one falls short

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

Stytch

  • Free tier limited to 10,000 monthly active users; scaling beyond this requires custom pricing negotiation
  • Fraud prevention capabilities billed at $0.005 per fingerprint for usage exceeding 10,000 free checks
  • Additional SSO or SCIM connections beyond the 5 included in free tier cost $125 each
  • Brand customisation and email removal require one-time payment of $99
  • HIPAA and advanced fraud protection only available in Enterprise tier
  • No native UI builder; requires custom frontend development for fully-branded auth flows

Syft

  • Lockfile parsing can drop packages silently. An open issue filed in August 2026 reports the yarn v1 cataloguer returning 118 of 745 packages with no error raised, which means a complete bill of materials and an 84 percent incomplete one look identical to the caller.
  • Fidelity varies sharply by ecosystem. Conan for C and C++, Haskell and Terraform get cataloguer support with no licence data, no dependency relationships and no file ownership, so a C and C++ shop gets the least from it.
  • Binary classification yields no licence or dependency metadata, and vendored or statically linked code is exactly where supply chain risk hides, so the blind spot and the risk overlap.
  • Incorrect CPE values and CPE collisions are recorded as open issues, and since Grype matches on CPE and PURL, an inventory error becomes a false negative in the security report downstream.
  • An inventory is not a risk assessment. Even a perfect bill of materials says a vulnerable version is present, never that the vulnerable function is called, and the triage burden lands entirely on the reader.

Answered from the vendors’ own pages

Stytch: What is included in Stytch's free tier?

The free tier includes 10,000 monthly active users (human and AI agents), unlimited organisations, 5 SSO or SCIM connections, and 1,000 machine-to-machine tokens with full authentication features.

Source
Syft: Does Syft find vulnerabilities?

No. It produces an inventory. Grype, from the same company, matches that inventory against vulnerability feeds. They are separate tools and the distinction is frequently lost.

Stytch: Does Stytch support AI agent authentication?

Yes. Stytch provides native AI agent authentication and authorisation, with support for the Model Context Protocol (MCP) for authenticating AI agents accessing external systems.

Source
Syft: Does anything in the Anchore stack do reachability analysis?

No. Neither Syft, Grype nor the commercial Anchore platform performs call graph or reachability analysis, so none of them tells you whether a vulnerable code path is actually invoked.

Stytch: What fraud prevention features does Stytch offer?

Stytch includes bot detection with 99.99% accuracy, device fingerprinting, invisible CAPTCHA, and zero-day device intelligence built into all tiers.

Source
Syft: Is it a CNCF or OpenSSF project?

No. It is single-vendor open source owned by Anchore, with no foundation governance. That is a different licence risk profile from Sigstore.

Syft: What does Anchore Enterprise cost?

Not published. The pricing page is contact-sales only, with named but unpriced commercial and federal tiers.

Syft: How do I know my SBOM is complete?

You largely cannot, which is the honest answer. Silent partial parsing is a known open defect, so a bill of materials used for compliance should be spot-checked against a known dependency list.
