I don't think "popo" is really a problem, but the name just doesn't sound good to me. It feels awkward to a native English speaker.

If it were my project, I would first look to the generic TLDs, and choose one that pairs nicely with the word "clip" or "clips", or something similar (but not Clippy LOL).

I would look through https://domcomp.com, filter by "gTLDs" (and maybe ccTLDs also).

Here are a few I see at a glance (not checking whois):

    clip.stream
    clip.link
    clip.dog (with a dog mascot / logo maybe)
    clip.show
    clip.watch
    clip.zone
    clip.rip
    clip.it / clips.it
    clips.lol

Good luck with your project :)

Thank you for response. I thought about clip.X, but didn't found any I like. Will think again. BTW opened site you linked only with www. added.

I wonder why Clippy is not and lol?)
