Everything here is free. Use it, break it, tell me where it fell short.
GA4 Auditor
Runs 56 checks on your GA4 property and tells you what to fix first. Free, read-only, takes about a minute.
Sign in with Google, pick a property, and get a health score with the issues sorted by how much they matter.
It checks the setup (data retention, Google Signals, enhanced measurement, key events, custom definitions, links to Google Ads and BigQuery) and the data itself (duplicate transactions, personal data in URLs, odd traffic sources, sudden jumps).
It only asks for read-only access. It cannot change anything in your account, and it does not keep your data.
An open-source Claude Code plugin that turns Claude into a GA4 analyst - what-changed reports, health checks and the context it needs to explain why.
Totals hide the story. Revenue can look flat while one product drops and another carries it. The plugin checks every breakdown for you and explains what moved.
You need Claude Code. Install it with one command from the GitHub page, then run /ga4-setup.
