Authentication
Auth providers such as Clerk, Auth0, and Supabase Auth — and how to pick the right one for your app.
Authentication handles user identity: sign-up, sign-in, sessions, and permissions. Choosing the right provider early avoids painful migration later.
What StackPilot recommends
- Clerk — drop-in UI and session management, great for modern web apps.
- Auth0 — enterprise-grade identity with many integrations.
- Supabase Auth — built into the Supabase platform with Postgres.
- NextAuth.js — open-source auth for the Next.js ecosystem.
How to choose
- Need social login and magic links quickly? Choose a hosted service like Clerk.
- Already using Supabase for your database? Use Supabase Auth.
- Want to self-host and control everything? Pick an open-source option.
