The short version

  • Only Syft has a free tier, so it costs nothing to try first.
  • Each has a real cost: OpenCities population-based pricing model limits scalability for growing municipalities; 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.
  • They diverge on capability: OpenCities covers Website Management, Syft covers Multi-format output.
  • 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.

OpenCities

  • Population-based pricing model limits scalability for growing municipalities
  • No self-hosted or on-premises deployment option
  • Limited code customization without vendor support

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

OpenCities: Does OpenCities work offline?

No, OpenCities is a cloud-based SaaS platform that requires an internet connection. All editing and management is done through web browsers.

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.

OpenCities: What accessibility standards does OpenCities meet?

OpenCities is maintained to comply with WCAG AA requirements, ensuring equitable access to government services and information for all residents.

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.

OpenCities: Can I integrate OpenCities with other government systems?

Yes. OpenCities integrates with Google Analytics, govDelivery for notifications, EngagementHQ for feedback collection, Legistar for meeting management, and Active Directory for intranet workflows.

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.
