What is Clerk?

Clerk is building auth for machines: API keys, a CLI agents can drive, per-verification pricing.

Two threads dominate. The first is machine authentication: API keys reached general availability with usage-based billing at $0.001 per creation and $0.00001 per verification, and a new CLI is described as a tool for developers and their agents to manage auth and billing. The second is enterprise readiness — Directory Sync (SCIM) generally available with custom attribute mapping and IdP role assignment, plus an Application Logs event stream across auth, billing, and organizations. Dashboard polish and Expo theming fill in around them.

What is Grype?

Grype's entire roadmap is false positives — and it just went code-aware to cut them.

Almost every release in this window targets match accuracy rather than coverage. Go has taken the brunt of it: merging govulndb GO-* records with their GHSA aliases, scoping GHSA twins by shared CVE, disabling stdlib CPE matching by default, and ignoring compiler CVEs when an image contains only a compiled binary. Coverage still widens at the edges — Zarf packages, Ubuntu ESM, Chainguard OSV data, CycloneDX 1.7 input — but it is not where the effort sits.

Clerk is building auth for machines: API keys, a CLI agents can drive, per-verification pricing.

◆ Current state

Two threads dominate. The first is machine authentication: API keys reached general availability with usage-based billing at $0.001 per creation and $0.00001 per verification, and a new CLI is described as a tool for developers and their agents to manage auth and billing. The second is enterprise readiness — Directory Sync (SCIM) generally available with custom attribute mapping and IdP role assignment, plus an Application Logs event stream across auth, billing, and organizations. Dashboard polish and Expo theming fill in around them.

◆ Where it's heading

Clerk is extending from human sign-in toward credentials for software acting on a user's behalf, and pricing that surface by the call rather than by the seat. The CLI framing makes the direction explicit: the control plane should be operable by an agent, not only by a person in a dashboard. Meanwhile SCIM, logs, and billing controls are the enterprise checklist that lets it sell upmarket while that bet plays out.

◆ Prediction

Expect the machine authentication suite to deepen around delegated and scoped access for agents — finer-grained key permissions or short-lived credentials — with usage-based pricing extended to whatever ships next.

Grype's entire roadmap is false positives — and it just went code-aware to cut them.

◆ Current state

Almost every release in this window targets match accuracy rather than coverage. Go has taken the brunt of it: merging govulndb GO-* records with their GHSA aliases, scoping GHSA twins by shared CVE, disabling stdlib CPE matching by default, and ignoring compiler CVEs when an image contains only a compiled binary. Coverage still widens at the edges — Zarf packages, Ubuntu ESM, Chainguard OSV data, CycloneDX 1.7 input — but it is not where the effort sits.

◆ Where it's heading

The arc runs from naive SBOM-to-CVE matching toward evidence-based matching. Reachability analysis is the clearest marker: grype is beginning to reason about whether vulnerable code is actually reachable rather than merely present. The parallel stream of ecosystem-specific correctness work — RHEL minor version streams, RHSA duplication, distro version parsing — suggests the same per-ecosystem treatment is being worked through one package manager at a time.

◆ Prediction

Reachability shipped for Go only. Extending it to a second ecosystem is the obvious next step, and Java or JavaScript are the likeliest targets given where SBOM false positives concentrate.
