Krabs

Multi-tenant Express.js middleware for Next.js

Krabs is an Express.js middleware that allows you to serve hundreds of different websites using only one Express.js and Next.js instance.

Multitenancy is a reference to the mode of operation of software where multiple independent instances of one or multiple applications operate in a shared environment. The instances (tenants) are logically isolated, but physically integrated. (source)

Thanks to Krabs, we can host multiple websites inside of our Next.js instance and serve them separately depending on the domain that the user is browsing:
