Features Overview
Clerk made auth enjoyable. We added sign-up, sign-in, user profiles, and organization management to a Next.js app in 15 minutes. The pre-built components are customizable, look professional, and handle edge cases like email verification and password reset automatically. The first-class Next.js middleware integration is the best in the industry.

Deep dive: Auth0 full analysis
Features Overview
Auth0 was the auth standard before Clerk arrived. It handles every auth scenario — social login, SAML, LDAP, machine-to-machine, passwordless. For B2B SaaS selling to enterprises that require specific identity providers and compliance certifications, Auth0 is still the safe choice. But the Okta acquisition brought price increases and the setup remains significantly more complex than Clerk.
Pricing Breakdown (April 2026)
| Plan | Price | Key Features |
|---|---|---|
| Free | $0 | 7,500 MAU, 2 social connections |
| Essential | $35/mo | 500 MAU included, custom domains |
| Professional | $240/mo | 1,000 MAU, MFA, advanced roles |
| Enterprise | Custom | SAML, SSO, SLA, dedicated support |
Who Should Choose Auth0?
- B2B SaaS selling to enterprises requiring SAML
- Apps needing machine-to-machine authentication
- Compliance-heavy industries (healthcare, finance)
- Teams needing 30+ identity provider options

Who Should Choose What?
→ Choose Clerk if:
You're building a modern web app with Next.js, React, or any JS framework and want auth done in 15 minutes with beautiful components. Best for B2C SaaS, startups, and teams that value developer experience.
→ Choose Auth0 if:
You're building B2B SaaS for enterprise clients who require SAML, specific identity providers, machine-to-machine auth, or complex role-based access control. Best for compliance-heavy industries like healthcare and finance.

For free open-source auth, Supabase Auth or NextAuth.js are solid options. For simple apps with basic login, Firebase Auth works well and is free for most use cases.

Frequently Asked Questions
Editor's Take
I've implemented auth with both. Clerk took 15 minutes. Auth0 took 2 hours and three Stack Overflow tabs. The Clerk components just work — sign-up, sign-in, user profile, organization management. If your enterprise clients don't specifically demand SAML or LDAP, don't overcomplicate it. Go Clerk.
