See which auth tool is the better fit for your startup." source: https://appstackbuilder.com/compare/clerk-vs-nextauth retrieved: 2026-08-30 --- AuthResearched · June 2026 # Clerk vs NextAuth.js: Which is Better in 2026? Clerk and NextAuth (now Auth.js) have long been the two go-to authentication choices for Next.js apps, but the landscape shifted in 2026\. Clerk is a hosted authentication service with polished drop-in UI components and a managed backend. NextAuth/Auth.js is the free, open-source library that deeply integrates with Next.js — OAuth providers, passwordless and credentials login, JWT or database sessions — with no vendor lock-in. The crucial 2026 update: Auth.js (formerly NextAuth) is now in maintenance mode — security patches only, no new features — after the project’s momentum shifted toward Better Auth. That reframes this comparison: Clerk vs NextAuth is now mostly a question for teams already on NextAuth, while new projects increasingly weigh Clerk against Better Auth instead. Below: status & maturity, features, pricing, control & lock-in, and how to choose. Quick verdict Pick Clerk when you want fully managed, polished auth with drop-in UI, organizations, and a 50K-MAU free tier — the fastest path to production for a new Next.js app that doesn’t want to self-host. Pick NextAuth/Auth.js if you’re already running it, want a completely free, open-source library with no vendor lock-in, and are comfortable implementing advanced features yourself — but note it’s in maintenance mode in 2026, so for a brand-new project you should also seriously consider Better Auth. In short: Clerk for managed convenience, NextAuth for free open-source control (with its maintenance-mode caveat). ## Clerk vs NextAuth.js — Side by Side | | Clerk | NextAuth.js | | -------------- | ------------------------------------ | ----------------------------- | | Category | Auth | Auth | | Pricing | Free · paid from $25/mo | Free | | Starting price | Free tier available | Free tier available | | Free tier | ✓ | ✓ | | Rating | 4.8 | 4.7 | | Best for | Auth — authentication, authorization | Auth — authentication, nextjs | ## Clerk vs NextAuth.js: The Details That Matter ### 01Project status & maturity (2026) The single most important 2026 development: Auth.js (formerly NextAuth) is now in maintenance mode — receiving security patches but no new features — as the ecosystem’s energy moved to Better Auth. It remains a valid choice for projects already running it that don’t want to migrate. Clerk is actively developed and expanding, with frequent feature releases and a growing enterprise story. For a new build, Clerk is on an upward trajectory while NextAuth is in maintenance. NextAuth/Auth.js is in maintenance mode (security patches only) in 2026; Clerk is actively developed — a key factor for new projects. ### 02Features Clerk ships a full feature set out of the box: pre-built UI components, a user-management dashboard, OAuth/social login, session management, email/password auth, and organizations — with MFA, passkeys, and enterprise SSO available on paid tiers. NextAuth/Auth.js gives you OAuth providers, passwordless and credentials auth, and JWT or database sessions with strong security defaults — but there’s no built-in 2FA, passkeys, organizations, or RBAC, and no admin dashboard. You implement those yourself. Clerk includes UI, orgs, and a dashboard (MFA/SSO on paid tiers); NextAuth covers core OAuth/sessions but leaves 2FA, orgs, and RBAC for you to build. ### 03Pricing NextAuth/Auth.js is completely free and open source — your only costs are the database and infrastructure you already run. There’s no per-MAU billing at any scale. Clerk is free up to 50,000 MAU, then $25/mo plus $0.02 per additional MAU, with some features (MFA, enterprise SSO at \~$75/connection, SOC 2 on the Business tier) costing extra. Affordable early, but it climbs at scale — roughly $2,025/month at 100K MAU. NextAuth is free at any scale; Clerk is free under 50K MAU then per-MAU pricing that grows (≈$2,025/mo at 100K MAU), with some features gated. ### 04Control, lock-in & data NextAuth runs inside your Next.js app with no vendor lock-in: you own the flows, the data lives in your database, and auth flows are highly customizable — at the cost of building and maintaining the backend yourself. Clerk is a hosted service: user data lives on Clerk’s servers and you adopt its auth flows, which means vendor lock-in and less flexibility for highly custom logic — in exchange for zero maintenance. NextAuth = self-hosted, no lock-in, your data and flows; Clerk = hosted, less custom-flexible, but zero maintenance. ### 05How to choose (2026) Stay on NextAuth/Auth.js if you’re already running it, value a free open-source library with no lock-in, and don’t need its missing features urgently — just factor in that it’s in maintenance mode. Choose Clerk if you want managed, polished auth fast for a new Next.js app. And if you’re starting fresh and want open-source without the maintenance-mode caveat, weigh Better Auth (which absorbed Auth.js’s momentum) alongside Clerk. ## Pros & Cons ![Clerk](https://appstackbuilder.com/clerk.svg) [Clerk](https://appstackbuilder.com/tools/clerk) * ✓Excellent developer experience * ✓Prebuilt auth UI saves time * ✓Strong Next.js and React integration * ✓Handles organizations and roles well * ✗Pricing scales with MAUs * ✗Vendor lock-in for auth flows * ✗Less flexible for highly custom auth logic ![NextAuth.js](https://appstackbuilder.com/nextauth.png) [NextAuth.js](https://appstackbuilder.com/tools/nextauth) * ✓Completely free and open source * ✓Deep integration with Next.js * ✓No vendor lock-in * ✓Highly customizable auth flows * ✓Strong security defaults * ✗Requires backend setup and maintenance * ✗No built-in admin dashboard * ✗Not beginner-friendly compared to hosted auth services ## Key Features Compared ### Clerk * ✓First 10,000 monthly active users included * ✓Usage-based pricing for additional MAUs * ✓Email & password authentication * ✓Social logins * ✓User management dashboard * ✓Prebuilt UI components ### NextAuth.js * ✓Unlimited users * ✓OAuth providers (Google, GitHub, GitLab, etc.) * ✓Email / passwordless authentication * ✓Credentials-based authentication * ✓JWT and database sessions * ✓Built-in CSRF protection ### Choose Clerk if… * ✓You want fully managed auth with drop-in UI, organizations, and a dashboard — working fast. * ✓You’re under \~50K MAU and value Clerk’s free tier and zero maintenance. * ✓You want MFA, passkeys, and enterprise SSO available without building them yourself. * ✓You’d rather not host or maintain authentication infrastructure.
