For a Fathom Lite evaluation, first identify the exact open-source repository and its maintenance state; similarly named hosted products may have different code and terms. Install it on a test site, generate known visits, and compare the resulting counts and referrers with expectations.
Review privacy, retention, backups, and an export path. If the lite edition is not actively maintained for your runtime, weigh that risk against an actively supported analytics tool. The goal is durable, appropriately minimal measurement—not just a simple-looking dashboard.
