I am writing it as a Linux user who is seeking for the client app of this network.
When selecting first download option - Patchwork, i am linked to https://ahdinosaur.github.io/patchwork-downloader/ where is a link to https://github.com/ssbc/patchwork/releases/tag/v3.18.1 and this page shows a banner "This repository was archived by the owner on May 12, 2021. It is now read-only." and it says that the development stopped.
Second download option - Patchbay I can find https://github.com/ssbc/patchbay/releases where the last release is around 6 years ago ( https://github.com/ssbc/patchbay/issues/393 ).
Last possible option - Manyverse at Manyverse at https://gitlab.com/staltz/manyverse/-/releases shows last release 2019, but https://www.manyver.se/ shows version just one year old.
More apps/clients are linked from: https://handbook.scuttlebutt.nz/applications
After checking these, i have found: https://github.com/rogeriochaves/feedless?tab=readme-ov-file (release 5 years ago, no instructions on how to use .zip file on a release page).
I ended up installing Manyverse .deb since it is reasonably up to date ATM. Connecting the networks seems to be problematic and not easy to figure out: since i know no user of this network, i went to https://github.com/ssbc/ssb-server/wiki/%23ssbrooms#public-rooms where i have created invite on the linked servers (only minority server web pages loaded), clicking invite link opened Manyverse app, but nothing happened (Debian 13 + KDE). Connections tab shows "Not connected". "Other choices" button has option to paste invite code.
Pasting there the "net:ssb-*" starting lines from above linked page: net:ssb-room.64-225-52-67.nip.io:8008~shs:uJXk9Aq2zRnIWUXipnDJkKsnLRzVoLGAY5SGaX3x1UY=:SSB+Room+PSK3TLYC2T86EHQCUHBUHASCASE18JBV24=
net:ssb-room.lohn.in:8006~shs:4FiUoVBSr0Byo2njngIrqUDs2QJOEzALzysYIuqQ4zA=:SSB+Room+PSK3TLYC2T86EHQCUHBUHASCASE18JBV24=
after like 10 minutes, the Connections tab shown: "Too few connections".
Above linked rooms page also mentions room maintainers addresses and when i paste these into the search field (magnifier icon), it loads user and i can follow them.
App feels pretty slow regarding network. Public tab does not seems to load content for minute/s. After like 15 minutes of waiting and trying, it connected properly and shows post of a followed users (i have followed several as mentioned earlier. Though these users are not my area of interest and makes me wonder if unfollowing them or if single room server goes offline, would decrease my connections count/disconnect me.
