Authentication
Authentication and user management platform with prebuilt UI, sessions, organizations, and MFA. Clerk has official SDKs and quickstarts for TanStack React Start and React Router. It is especially relevant for teams building with Start, Router.
Clerk is a current TanStack partner, and we think they are a strong option for teams building in this part of the stack.
Clerk packages the painful parts of auth, including sign-in, sign-up, sessions, organizations, and MFA, into a well-documented product with good UI primitives.
Their official TanStack React Start and React Router support makes it easier to add auth without fighting route protection, session handling, and user flows.
