I would like to suggest you to support the linking between papeeria and gitlab folders: really often gitlab does not provide .git protocol, but only https or ssh ones.
I had to mirror private gitlab in github to achieve the sync with papeeria, but I would really like to stick to my private gitlab instead of using a public access git mirror.
Many thanks, kind regards

you can sync Papeeria project with repository hosted on GitLab over SSH protocol if you upload your public key into your GitLab account. It works for private projects as well, provided that you're using paid plan on Papeeria (just've tested it).
