We agree with Plausible about almost everything. Where we differ is scope.
Skomi covers apps as well as sites. Native SDKs for iOS, Android, Flutter, React Native, Unity and desktop report into the same account as your sites. Plausible is sites only.
Skomi shows you the page, not only the numbers. Heatmaps and session recordings are part of the same product, so "which page loses people" can be followed by "watch somebody lose it". Plausible does not do these, by choice, and it is not an omission on their part.
Skomi collects what your visitors say, too. Feedback boards, voting and a widget sit alongside the analytics, so the reason behind a number has somewhere to live.
Our script is bigger, because it does more. It is 11.7 KB gzipped, and here is what is in it. Plausible's is smaller, and if that matters more to you than heatmaps do, that is a real answer and Plausible is the better tool.
