I think there is some confusion here.

Paperwork is a desktop application, not a web application. (eh, self-hosting doesn’t necessarily always imply web applications ! :). I for one use Nextcloud and nextcloud-desktop to keep my Paperwork work directories in sync on all my computers.

Paperless is a web application. Paperwork is a desktop application.

Paperwork seems to fit most of the bill except for one thing: it won’t scroll to where the search hit is (but it will highlight the matching keywords).

Just beware Paperwork won’t just create an index. It’ll organize the PDF its own way in its own work directory.

(full disclosure: I’m its main dev)

I use OPNSense virtualized on top of Proxmox. Each physical interface of the host system (ethX and friends) is in its own bridge (vmbrX), and for each bridge, the OpenSense VM also has a virtual interface that is part of the bridge. It has worked flawlessly for months now.
