Key Points
- Drop-in UI components:
<SignUp/>,<SignIn/>, profile management, org switcher, billing plans - B2B multi-tenancy with custom RBAC roles, invitations, and org auto-join
- Billing beta: subscription management via drop-in React components, no custom payment code
- Auth features: MFA, social SSO, passkeys, magic links, OTP, bot detection, session management
- SDKs for all major frameworks; free for first 50K monthly retained users
- MCP server available for agent integrations
Insights
Clerk occupies the “auth-as-a-service” space that used to require Auth0 or building in-house. The addition of billing (subscriptions) alongside auth is a notable moat expansion — combining identity and payments data under one umbrella simplifies B2B SaaS bootstrapping significantly. The free tier generosity (50K MAU) is a land-and-expand strategy common among developer tools.
