Strengths & Weaknesses
Clerk
Exceptional developer experience with pre-built UI components that work out-of-the-box in minutes
Comprehensive authentication features including MFA, social OAuth, passwordless, and custom session management
Built-in multi-tenancy and organization management ideal for B2B SaaS applications
Generous free tier with 10,000 MAUs making it cost-effective for startups and small projects
Costs can escalate quickly with add-ons - enhanced features like unlimited impersonation, multiple SAML connections, and advanced B2B features each cost $85-100/mo additional
Some users report frustration with low usage caps and the need for multiple add-ons to unlock full functionality
Enterprise features like SAML SSO are metered and can become expensive for applications with many connections
NextAuth.js
Free and open-source with no usage limits or pricing tiers to worry about as you scale
Native Next.js integration with excellent support for App Router, Server Components, and Edge Runtime
Extensive provider support with 60+ OAuth providers pre-configured and ready to use
Flexible session management supporting both JWT and database-backed sessions
Documentation can be outdated or incomplete, especially for newer Next.js App Router patterns
Custom authentication flows and advanced features like MFA require significant additional implementation work
Limited to Next.js ecosystem - not suitable for multi-platform applications requiring web, mobile, and desktop auth
