Supabase Auth vs Clerk for social login

If your main goal is social login (Google, GitHub, Apple, etc.), both Supabase Auth and Clerk can do it well—but they optimize for different things.

Quick take

• Choose Clerk if you want the smoothest developer experience, polished UI components, and fewer auth headaches.
• Choose Supabase Auth if you already use Supabase/Postgres and want auth tightly integrated with your database and backend.
