What is Clerk?

Clerk shipped a CLI for humans and agents, monetized API Keys, and graduated SCIM — auth for the agentic era.

April was a strategically dense month. Clerk shipped a new CLI that the company explicitly frames as a tool for both developers and their agents to manage authentication and billing. API Keys went GA with usage-based pricing live (1,000 free creations and 100,000 verifications monthly, then per-unit). SCIM Directory Sync went GA with custom attribute mapping and IdP-group role assignment in beta. Smaller items rounded it out: Expo JSON theming for native components, infinite-scroll dashboard tables, test-user filtering in analytics, and Clerk Billing additions (annual-only plans, seat-limited plans). The captured feed also picked up the marketing landing page mentioning a $50M Series C.

What is Depot?

Depot turns its build-acceleration compute into a metered backend for AI agents.

Depot is shipping fast across two fronts: hardening its CI platform and opening its compute to AI workloads. Recent CI work includes native step retries, durable cache disks, and a generally available API and CLI with full dashboard parity. On the AI front it added SOCI v2 to cut startup time for large CUDA and PyTorch images and launched a Sandbox SDK to run untrusted or agent-generated code in ephemeral, billed sandboxes.

Clerk shipped a CLI for humans and agents, monetized API Keys, and graduated SCIM — auth for the agentic era.

◆ Current state

April was a strategically dense month. Clerk shipped a new CLI that the company explicitly frames as a tool for both developers and their agents to manage authentication and billing. API Keys went GA with usage-based pricing live (1,000 free creations and 100,000 verifications monthly, then per-unit). SCIM Directory Sync went GA with custom attribute mapping and IdP-group role assignment in beta. Smaller items rounded it out: Expo JSON theming for native components, infinite-scroll dashboard tables, test-user filtering in analytics, and Clerk Billing additions (annual-only plans, seat-limited plans). The captured feed also picked up the marketing landing page mentioning a $50M Series C.

◆ Where it's heading

Two arcs are converging. First, Clerk is staking out auth-for-agents: the CLI is designed to be agent-callable, API Keys are the substrate agents need to act on behalf of users, and the metered billing model lets that scale without per-seat friction. Second, Clerk is closing the enterprise B2B feature gap with SCIM Directory Sync GA — the move that lets it sell into IT-procurement-driven deals where WorkOS has been winning. The Billing surface continues to deepen, increasingly looking like a real billing product rather than just an auth add-on.

◆ Prediction

Expect the Clerk CLI to gain MCP-friendly commands and scripted-onboarding templates within a release or two, and the SCIM beta features (custom attributes, role assignment) to graduate quickly given the GA framing. Clerk Billing's monetization surface should keep widening — usage-based metering for more primitives, possibly tied to AI/agent activity directly.

Depot turns its build-acceleration compute into a metered backend for AI agents.

◆ Current state

Depot is shipping fast across two fronts: hardening its CI platform and opening its compute to AI workloads. Recent CI work includes native step retries, durable cache disks, and a generally available API and CLI with full dashboard parity. On the AI front it added SOCI v2 to cut startup time for large CUDA and PyTorch images and launched a Sandbox SDK to run untrusted or agent-generated code in ephemeral, billed sandboxes.

◆ Where it's heading

Depot is extending from build and CI acceleration toward being a general compute backend for agents. The Sandbox SDK, the agent-friendly GA API, and ML-image startup optimizations point the same way: sell fast, isolated, metered compute that AI tools and pipelines can drive programmatically. The CI improvements keep the core product sticky while the platform broadens.

◆ Prediction

Expect the Sandbox SDK to move toward general availability with more language and filesystem surface, and continued convergence of CI and sandbox compute under one metered, API-first platform.
