That’s fair enough. I’ve gotten a number of non-devs hooked on docker containers for running self-hosted apps that didn’t have a desktop counterpart, but admittedly they were otherwise technically oriented. OP might want to look into it if they’re so inclined, but it’s easiest to just use Voyager from the website :)
Voyager is mobile-first, but can be run as a webapp frontend that you can host locally (out of a repo or docker container), or set up for web access. If it’s just keyword filtering you’re after you can also use ublock origin rules to do that (in fact there was a lemmy thread today talking about it somewhere) You can set rules like
lemmy.ml##.post-listing:has(.post-title:has-text(/trump|elon|musk|biden|kamala|rfk/i))
and the content will simply not render.
