Next.js Anleitung Best Authentication for Next.js (2026)
Compare the best authentication solutions for Next.js 14+. We review Clerk, Auth.js, Supabase Auth, and more with App Router compatibility and Edge Runtime support.
Choosing the right authentication solution for Next.js is critical. You need something that works with the App Router, supports Edge Runtime, and doesn't add complexity to your codebase. We've tested the top options to help you decide.
Warum es wichtig ist
Next.js 14's App Router and Server Components change how auth works. Session management, middleware, and protected routes all need to work seamlessly with React Server Components. Edge Runtime compatibility matters if you're deploying to Vercel's edge network. The wrong choice can mean auth bugs, poor DX, and hours of debugging.
Wichtige Überlegungen
App Router Compatibility
Does the auth library have first-class support for Next.js 14's App Router, Server Components, and Server Actions? Legacy libraries designed for Pages Router may not work correctly.
Edge Runtime Support
If you're using middleware for auth checks or deploying edge functions, the library needs to work in Edge Runtime (no Node.js APIs like fs or crypto).
Session Strategy
JWT (stateless, edge-compatible) vs Database Sessions (more secure, requires DB calls). Your choice affects where you can deploy and latency.
Social Providers
Which OAuth providers do you need? Most solutions support Google, GitHub, and common providers. Enterprise SSO (SAML, OIDC) requires specific solutions.
Managed vs Self-Hosted
Managed services (Clerk, Auth0) handle everything but cost more. Self-hosted (Auth.js) is free but requires more setup and maintenance.
Unsere Empfehlungen
Clerk
Beste Gesamtlösung Ausgezeichnet Unterstützung Offizielles SDKClerk has the best Next.js integration, period. First-class App Router support, Edge-compatible middleware, drop-in components, and excellent docs. The free tier (10k MAU) is generous for indie projects. Only downside: it's a managed service with vendor lock-in.
npx create-next-app@latest --example with-clerk 
Auth.js
Beste Selbst-gehostet Ausgezeichnet Unterstützung Offizielles SDKAuth.js (formerly NextAuth.js) is the go-to for self-hosted auth. Full App Router support in v5. Free and open source. Requires more configuration than Clerk but gives you full control. Great for privacy-focused apps or when you need database sessions.
npm install next-auth@beta 
Supabase Auth
Beste mit Supabase DB Gut Unterstützung Offizielles SDKIf you're using Supabase for your database, their auth is a natural choice. Good Next.js support with SSR helpers. Free tier includes auth. Not ideal if you're not using Supabase as your database.
npx create-next-app -e with-supabase 
Kinde
Bester Kostenloser Plan Gut Unterstützung Offizielles SDKKinde offers a very generous free tier (10.5k MAU) and solid Next.js support. Good alternative to Clerk with competitive pricing. Newer but growing fast.
npm install @kinde-oss/kinde-auth-nextjs 
Auth0
Beste für Unternehmen Gut Unterstützung Offizielles SDKAuth0 is battle-tested for enterprise with SAML, LDAP, and advanced security features. Next.js SDK works with App Router. Higher learning curve and pricing than Clerk. Best for B2B apps needing enterprise SSO.
