Best for
Clerion Founders and small teams with no analyst, who want the interpretation done for them rather than another dashboard to read.
Fathom Agencies and anyone running many small sites, since the base plan already covers 50 of them.
Watch out for
Clerion It is built for site-wide traffic and growth questions. If you need programmatic event pipelines for a complex product funnel, a dedicated product-analytics tool fits better.
Fathom No free tier at all, and like Plausible it shows you the numbers without telling you what to do about them.

A simpler dashboard still has to be read
Fathom strips analytics to one clean screen with no cookies and no banner. Simpler is not the same as answered. You still scan the numbers each week and decide what matters. Clerion writes the decision.
When Fathom is the right tool
If you want straightforward, private traffic numbers on a fast dashboard, Fathom is a solid choice. Clerion fits when you want the briefing written for you.
Switching from Fathom
Export your Fathom data as CSV and drop it in. Clerion reads it in your browser and keeps two years of history. Paste one line, remove the Fathom script, and you are done.
