Authentication is handled by NextAuth.js in app/api/auth/[...nextauth].ts. This file configures the auth providers and handles the session strategy.

How it works

From repo URL to contributing - in three steps

01

Paste a GitHub URL

Drop in any public repository URL. Day Zero fetches the structure, key files, and architecture so you don't have to read through everything yourself.

02

Pick your role and level

Tell us whether you're Frontend, Backend, Full Stack, or DevOps and whether you're Junior, Mid, or Senior. Your kit is built around you, not a generic developer.

03

Get your personalized kit

Receive an architecture overview, a first-hour setup guide, hidden gotchas, a suggested first task, and a live chat - all grounded in the actual codebase.
