Running Multiple Apps Under a Single Domain with Vercel

I own the copdips.com domain, and need to point it at several Vercel apps so that:

• https://apps.copdips.com/app1 routes to https://app1.vercel.app
• https://apps.copdips.com/app2 routes to https://app2.vercel.app
• direct https://app1.vercel.app, still works as before
• direct https://app2.vercel.app, still works as before

This is a standard Multi-Tenant Routing with Context Awareness scenario. To serve both the root domain (app1.vercel.app) and the subpath version (apps.copdips.com/app1) from the same deployment, each app must become host-aware-effectively detecting whether the request comes through the main router or directly and adjusting asset URLs and links accordingly.

OIDC (OpenID Connect)

OIDC (OpenID Connect) is an authentication layer (verify identity + obtain profile) built on top of the OAuth2 protocol (authorization layer). It allows Web-based, mobile, and JavaScript clients to verify the identity of end-users based on the authentication performed by an authorization server (aka AS or IdP), as well as to obtain basic profile information about the end-user in an interoperable and REST-like manner. It eliminates storing and managing people's passwords.

Google Chrome DevTools MCP

Chrome DevTools MCP (Model Context Protocol) allows you to interact with Google Chrome programmatically through AI coding agents like Claude Code, Copilot, Codex, etc. This enables automated testing, debugging, and inspection of web applications directly from the command line.
