I think we see "frontend monitoring" in two different buckets: "metrics-oriented" and "incident-oriented". Metrics are about things like lighthouse scores, optimizing your frontend bundle, etc.. which tend to only become relevant for larger companies as only at that point do these things affect conversions to a significant level. Incidents, however, are more about one-off issues happening in your web app, and that' what we're focusing on at highlight.io (at least right now). Examples include customer support issues, bugs that affect a user's experience, etc..

Both are important for larger companies, but for smaller companies, the only thing that we see as relevant are frontend "incidents".

So to answer your question, I'd ask yourself what types of issues are you trying to track down? Does that make sense?
