Clerk
Clerk is what I use for authentication and billing because it turns what used to take days—providers, tokens, sessions, login UI—into minutes. In this build, it’s not just sign-in; it’s also subscription plans and enforcing limits so you can actually monetize your app.
You'll be taken to Jsm to complete your purchase.
Pros
- +Fast auth setup with minimal code
- +Handles user sessions and user management cleanly
- +Built-in billing support for subscriptions and plan limits
Cons
- -Some newer native UI components can require dev builds for Expo
