I guess the benefit of piku comes with the ease of use for developers who don't know lots about system administration/infrastructure.

Spinning up a server and installing a repo on it is easy. Depends on your use case and on what you know/have.

I prefer ansible or jenkins+scp-build-to-server+run-deploy.script

I added it to my tools list in case i need sth quick'n working for a small team/to recommend when there's no ansible/sysadmin knowledge available.

(I haven't looked into piku but i guess you'll hit its limitation once you have more complex deployment schemes, privilege/access management, ...)
