About

Clerk provides ready-made sign-in, sign-up, and user-profile components plus a Backend API for user management. The Hobby plan is free and, since February 2026, includes 50,000 monthly retained users, which counts users who return at least a day after signing up. It handles sessions, organizations, and social logins out of the box with polished UI components. The Backend API uses a secret key bearer token for admin tasks like listing users.
