## Setup Time & Developer Experience
### Clerk β 5-10 minutes
Fastest
Clerk offers the best developer experience for React/Next.js. Pre-built components like `` and `` work out of the box with minimal configuration.
npm install @clerk/nextjs
### Auth0 β 4-8 hours
Most Complex
Auth0 is powerful but requires more configuration. Universal Login setup, callback URLs, and custom rules take time. Great docs, but steeper learning curve.
### Supabase Auth β 1-2 hours
If using Supabase
Seamless if you're already using Supabase. Auth is built-in with the JS client. However, you'll need to build your own UI components for sign-in/sign-up flows.
## When to Use Each
### Choose Clerk if...
* β You're building with Next.js or React
* β You want beautiful pre-built auth UI
* β You need B2B features (organizations, team management)
* β Developer experience is a priority
### Choose Auth0 if...
* β You need extensive compliance certifications
* β You're building enterprise software
* β You need advanced security features (anomaly detection)
* β Budget isn't a primary concern
### Choose Supabase Auth if...
* β You're already using Supabase for database
* β You want the most generous free tier
* β You prefer open-source solutions
* β You're comfortable building custom UI
