Tons of red flags here.

I've been around for a while and have never heard of this client.
Browsing the site, all the pages dedicated to code or developer documentation are non-existent or lead to placeholders.
I reached out to Will Binns whose name is given as the maintainer of
the ostensible &quot;Bitcoin client&quot; Bitly Core on the &quot;developer
documentation page&quot; (which looks like it was scraped from
bitcoin.org). Will Binns tells me that he is unaffiliated with the
project.

The obvious explanation is that the software is either malware or part of a scam. I would recommend that you do not install it, do not let it interact with any wallet backups, and regard anyone who recommended its use with suspicion.
