https://d2c.io is pretty decent. Not open-source but self-hosted and does clustering well. They have a Discord channel I nudged them to setup but it only gets a post every few months. Decent project though and some solid app-stacks packaged for one-click installs.
@robi everything you referenced to the install lol worked for ATT installing U-verse and I've seen all types of IW - single family homes, multi dwelling unit, duplex, from band new homes with ethernet to every jack an a nice patch panel to 100+ year old Victorians with no cat5 and where you cant drill anywhere lol I understand Star Links hands off approach could be good for local techs but yeah the complexities of install a new connection into an existing home network is not always as simple as: "run the line and connect it"
