These Homepage services really fall into a gap of usefulness. They don't provide the level of monitoring you actually want, yet they're complete overkill for just a bookmark UI. They also need to work with everyone's jank so they get overly complicated.
If you just want links, just write the HTML and spend an afternoon fiddling with the CSS. If you want some level of monitoring, you can write some JS to see if they can connect to the service. Any more monitoring and you'll want something like Prometheus/grafana.
