Users switch for transparent pricing, better developer experience, and frontend-first approach. Clerk's Organizations feature and React/Next.js components are praised. Simpler than Auth0 for most use cases.

Developers migrate for built-in biometric and Web3 authentication, composable APIs, and detailed migration guides from Auth0. Fraud prevention features included. Better for modern authentication needs.

Teams switch for the generous free tier (50,000 MAU), tight integration with Firebase ecosystem, and lower cost. Best for mobile apps and projects already using Google Cloud.

Open-source alternative for teams who want full control. Self-hosted means no MAU-based pricing. Eliminates vendor lock-in. Popular choice for privacy-conscious organizations.

Developers building on Supabase switch for integrated auth with their database. Simple, affordable, and avoids the complexity of standalone auth providers. Good for indie hackers and startups.
