Clerk
I used Clerk to handle sign-in, sign-up, and account management without wasting time building auth from scratch. The best part is the built-in billing, so I can lock premium AI tools behind a subscription and manage plans directly from the user’s account.

- +Built-in billing and plan management for subscriptions
- +Makes it easy to gate premium features based on user plan
Cons
- -Requires setting up keys and configuration in the dashboard
- -Billing features may need extra setup depending on region and plan
