GA4Spy is a useful developer tool - GetInlytics is a compliance audit
These tools serve different purposes. GA4Spy shows you what tracking tags are on a page in real time. GetInlytics audits whether those tags are legally and technically correct - scoring compliance against GDPR, CCPA, and ePrivacy. Most teams use both.

When you need more than tag detection
Tag detection tells you what is present. A compliance audit tells you whether it is correct.
Server-side scan - no extension needed
GA4Spy is a Chrome extension. GetInlytics runs entirely server-side from a URL - no installation, no browser, no permission grants. This matters when auditing client sites, running in CI, or sharing results with teammates who do not use Chrome.
GDPR compliance scoring
GA4Spy identifies what GA4 and GTM tags are present. GetInlytics goes further: it scores compliance against GDPR, CCPA, and ePrivacy, identifies consent violations, and generates a shareable report you can hand directly to a DPO or legal team.
Consent Mode v2 is now required
Since March 2024, Google requires Consent Mode v2 for all sites running Google Ads in the EEA. GA4Spy detects tags but does not verify whether Consent Mode v2 is correctly configured. GetInlytics checks all four consent signals and verifies they update after user interaction.
Cookie behavior testing, not just tag detection
Knowing that a GA4 tag is present is a starting point. Knowing whether it fires before consent is what matters for compliance. GetInlytics audits actual cookie behavior across pre-consent, Accept All, and Reject All states - then maps each cookie to its legal basis.
Frequently asked questions
What is GA4Spy?
GA4Spy is a free Chrome browser extension that detects GA4 measurement IDs, GTM container IDs, and dataLayer pushes on any website you visit. It is widely used by GA4 developers and analysts to quickly identify which analytics tags are present on a page. It operates client-side, reading the page as the browser renders it.
What does GetInlytics do that GA4Spy does not?
GetInlytics is a full compliance audit tool, not a tag detection extension. It runs server-side (no extension required), generates a GDPR/CCPA/ePrivacy compliance score, audits cookie behavior before and after consent, verifies all four Consent Mode v2 signals, reviews the GTM container for consent violations, and delivers a shareable scored report with per-issue fix recommendations.
Is GetInlytics free to use?
Yes. The full GA4 + GTM + consent + compliance audit is free with no login required. A shareable report is generated after every scan. Step-by-step fix guides for GA4 and GTM issues are available as purchasable downloads from the report page.
Do I need to install a Chrome extension?
No. GetInlytics is entirely server-side. You paste a URL and the tool scans the site from its own infrastructure. No browser extension, no Chrome, no local setup required.
