Clerk
Mentioned 8x by users

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.

Firebase Authentication

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.
