AWS Cognito

Setting up AWS Cognito for SSO is unreliable with multiple bugs and non-functional components. The integration experience is messy and frustrating, lacking stability and clarity.

AWS Cognito's December 2024 pricing restructuring introduced three tiers (Lite, Essentials, Plus) that increased costs 3-5x for many existing users. The pre-built hosted UI remains restrictive with limited customization options.

Auth0's SDK required weeks to support Next.js App Router compared to Clerk's day-one support. The SDK still requires significantly more configuration for equivalent functionality, and Cognito's documentation is confusing with unnecessarily complex configuration patterns.
