Fossil (https://www.fossil-scm.org) is superior for this use case in almost every way I can think of. It was in many ways designed for this use case.
A fossil repository is a single-file SQLite database. You can copy that single file to another computer and treat it like a remote, sync with it, etc. with a simple "fossil sync" command. The single file includes all the ticketing (issues), wiki, discussion forum and all branches, and those are all synced as well. There's no need to do any special packaging or bundling. Plus you get a built in web UI.
