What's your definition of Rails clone? MVC? If it is, sure, yeah, this and a whole bunch of other frameworks are Rails clones. Laravel is a Rails clone. Django is a Rails clone. We're all Rails clones!
Does the design of some of the logic look heavily-inspired by Rails? Sure, and I think it's a great choice.
But in reality, calling it a Rails clone is a disservice to Rails. Rails is much more than MVC and patterns implemented from Patterns of Enterprise Application Architecture. The power of Rails isn't in any single one of the patterns — sure, it may have started that way when it was common to ship PHP copy-pasted from php.net and deployed using Filezilla (or explorer.exe!) — but since, what, 2.3? the power of it has been it's ecosystem: nothing can come close to the vastness and maturity of Rubygems.
I don't know, the vastness of the JS ecosystem seems bigger to me? I have come across many third party service providers that do not offer Ruby SDKs but do for JS,Java,Python etc...
