Hi @iskurbanov
I’m following your guide on implementing a multi-tenant architecture for one of our existing products. However, we have a situation where our client already has separate hosting for domain.com and app.domain.com. Could you let me know if using wildcard subdomains might interfere with these existing domains?
Thanks!

Same question here, I've also implemented a multi-tenant app with i18n next-intl and it works but I still facing some conflict problems in the app structure, cuz I need to set up localization for the dashboard and landing page only without affecting the dynamic route like [domain]

Would it be possible for customers to bring their own custom domain instead of the wildcard ?

I've implemented analagous logic with the App dir and it's working perfectly well! If fact your file structure in the App dir will look exactly the same, just create the "site" logic in a page.tsx file instead of index.tsx.

I also added the following to route both my domain and localhost to another folder such that I could work with that instead of the root domain defualting to the DEFAULT_HOST like in this tutorial. Helped with running locally and debugging!

// rewrite root application to `/home` folder if ( hostname === "localhost:3000" || hostname === process.env.NEXT_PUBLIC_ROOT_DOMAIN ) { return NextResponse.rewrite( new URL(`/home${path === "/" ? "" : path}`, req.url), ); }

Same logic :)

Add the following logic for user1.hosted-url.com/about

if (url.pathname.startsWith('/about')) { url.pathname = `/sites/${data?.subdomain}${url.pathname}`
