Why the models rank Clerk — on best authentication provider for web apps
“Best developer experience in the category — drop-in prebuilt UI components, first-class Next.js/React SDKs, built-in B2B organizations/multi-tenancy, MFA and session management that work out of the box, generous 10k-MAU free tier; assumes the typical practitioner is a product team shipping a SaaS app fast rather than an identity specialist. Near-tie with Auth0 — Clerk wins on speed-to-ship, Auth0 on breadth.”
