Why are there two websites — Alokify.com and Alokify.net?

Because they serve different purposes:

Alokify.com → My custom frontend website, where I share my story, philosophy, and guide you in choosing the right product.
Alokify.net → My GoDaddy Reseller Storefront, where you browse services and place orders.

The separation is required because the reseller storefront runs on a different domain or subdomain from the custom frontend.
