## What it is
Remix Auth is a complete open-source authentication library for Remix and React Router applications, inspired by Passport.js and built on the Web Fetch API. It uses a strategy pattern where each authentication flow (form login, OAuth2, GitHub, etc.) is provided as a separate npm package plugged into a shared Authenticator class.

## Use cases
- add login with username and password to a Remix app
- authenticate users with OAuth2 providers like GitHub
- implement server-side session-based authentication in React Router
- build custom authentication strategies for a Remix app
- replace Passport.js in a modern Fetch API-based stack

## When to choose
- you are building a Remix or React Router app and need server-side authentication
- you want a Passport.js-like strategy ecosystem with full TypeScript support
- you need pluggable auth flows (form, OAuth2, social logins) with minimal setup

## When to avoid
- you need client-side-only authentication in a non-Remix SPA
- your framework is Next.js or another non-Remix/React Router stack
- you need a batteries-included auth service with built-in user management rather than a library
