I had an old website that was still on Google Analytics; and I just converted it to @plausible . First observations:
a) The ease! (script inclusion isn't some weird code, but just the request domain that identifies the requests)
b) Firefox suddenly started showing up again (from 0 to ~6%)
c) Just one page, again the simplicity overall, with all the statistics you want not 10 clicks away but in one screen.
Overall, very good! (likely to convert to paying)
