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: 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.
In short
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.
In short
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.
In short
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.
In short
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.

Which is rated higher, Clerk or NextAuth.js?⌄
In our catalog, Clerk rates 4.8 out of 5 and NextAuth.js rates 4.7 out of 5, so Clerk has a slight edge on reviews.
Is NextAuth still maintained in 2026?⌄
Only in maintenance mode — Auth.js (formerly NextAuth) receives security patches but no new features in 2026, as the ecosystem’s momentum shifted to Better Auth. It’s still fine for projects already running it, but for a brand-new app you should also consider Better Auth or Clerk.
Is Clerk or NextAuth cheaper?⌄
NextAuth is cheaper at scale — it’s completely free and open source with no per-MAU billing; you only pay for your existing database and infrastructure. Clerk is free under 50K MAU, then $25/mo plus $0.02/MAU, reaching roughly $2,025/month at 100K MAU, with some features costing extra.
Does NextAuth have built-in 2FA and organizations like Clerk?⌄
No — NextAuth/Auth.js covers OAuth providers, passwordless/credentials login, and JWT or database sessions, but there’s no built-in 2FA, passkeys, organizations, or RBAC; you implement those yourself. Clerk includes organizations and a dashboard out of the box, with MFA and SSO on paid tiers.
Should I use Clerk or NextAuth for a new Next.js app?⌄
Because NextAuth/Auth.js is in maintenance mode in 2026, a new Next.js app is usually better served by Clerk (for managed convenience) or Better Auth (for open-source control). Choose plain NextAuth mainly if you’re continuing an existing project that already depends on it.
