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 nuggets?

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.

nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.

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.

nuggets keeps compounding on the 2.0 rewrite — more pattern families, lighter install.

◆ Current state

nuggets searches for association rules, contrasts and other conditional patterns in the GUHA tradition, with a C++ core behind dig() and an interactive explore() app for reading results. Since the 2.0 rewrite of that core, every release has widened the same three surfaces: more pattern families to mine, more of explore() to inspect them in, and steady performance work underneath. The most recent tag optimises dig() on sparse crisp data with a sparse bit chain and adds clustering characteristics to explore() for association rules.

◆ Where it's heading

Two forces are shaping the package. One is coverage: baseline, complement and paired-baseline contrasts, correlations, tautologies, ancestors and clustering have all been added as first-class dig_ or explore_ surfaces, so the same search engine now answers a widening set of questions. The other is weight — Shiny packages moved from Imports to Suggests, BH and RcppThread dropped, XSIMD updated, parse_condition() rewritten in C++ — which keeps a package with an interactive app from forcing that app's dependencies on every user. Deprecations are handled through lifecycle rather than removed abruptly.

◆ Prediction

Expect the sparse-data optimisation to extend from crisp to fuzzy data, and explore() to keep gaining tabs as each new pattern family lands, on the roughly six-week cadence the 2.2 line has held.
