Should I self-host Fathom Analytics?

# Fathom Analytics — verdict log

- **Date:** 2026-08-10
- **Verdict:** YES — worth it
- **Protocol:** v1 (2GB reference env, Docker preinstalled, AI assistant: claude-code)

## Setup evidence (shared)

- This verdict rides on the same replacement verified for `plausible-plausible` — see `compose/plausible-plausible.yml` and its log.

## The call

Fathom charges $15/mo for privacy-friendly analytics; Plausible and Umami are the same promise as software you run. The Plausible compose on this scoreboard is already boot-verified — same replacement, same math, one more subscription that's really a database with a chart on top.
