The short version

  • Each has a real cost: REST Client VSCode limited to Visual Studio Code; not available as a standalone application; 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: REST Client VSCode covers REST Client, 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.

REST Client VSCode

  • Limited to Visual Studio Code; not available as a standalone application
  • No support for WebSocket, gRPC, or other advanced protocols
  • No cloud sync or team server features; requires Git-based workflow

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

REST Client VSCode: How much does REST Client VSCode cost?

REST Client VSCode is completely free and open source. It is available on the Visual Studio Code Marketplace with no subscription or licensing fees.

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.

REST Client VSCode: What authentication methods does REST Client support?

REST Client supports Basic Auth, Digest Auth, SSL certificates, Azure AD, and AWS Signature v4 authentication for API requests.

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.

REST Client VSCode: Can I save and manage multiple requests?

Yes. REST Client supports multiple requests per file using ### delimiters, request history with auto-save, environment variables for different configurations, and code snippet generation for multiple programming languages.

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.

REST Client VSCode: How do teams collaborate with REST Client?

REST Client requests are stored as text files that can be version-controlled in Git repositories. Teams collaborate by sharing requests through Git, making the API specs part of the codebase.

Source
Syft: What does Anchore Enterprise cost?

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

REST Client VSCode: What protocols does REST Client support?

REST Client primarily supports HTTP/HTTPS and GraphQL. It does not support WebSocket, gRPC, or other advanced protocols available in desktop clients like Insomnia.

Source
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.

REST Client VSCode: Is there cloud sync for REST Client requests?

No. REST Client has no built-in cloud sync or team server features. All collaboration and sharing relies on Git repository management.
