container audit
GTM-MRW746Q
This container can hand execution to 19 third parties — more than 97% of the 46,522 containers we have measured. Each serves code it controls, which can change at any time.
- 17 custom HTML tags carrying 114 KB of JavaScript — more than 70% of the 46,522 containers we have measured. This runs on every page the container loads on.

What we observed
A real browser loaded quantummetric.com a month ago and recorded every request it made. This is what happened, as distinct from what the container is configured to do. It is one page load — anything that fires only deeper in the site did not fire here.
Container loaded from
googletagmanager.com — GoogleMeasurement sent to
google-analytics.com — GoogleConsent
a consent platform is present, but our browser could not complete the accept step — so the before-and-after comparison did not run here. Google recorded
gcs=G111 (all granted).Third parties contacted
25 hosts — cdn.sanity.io, clients.abmatic.ai, static.claydar.com, cdn-cookieyes.com, www.googletagmanager.com, js.hsforms.net, waga1ps5is.kameleoon.io, visitor.abmatic.ai, and 17 more

Where the data goes
Not observed — on the page we loaded, measurement went to Google and nowhere else. observed on quantummetric.com More info »
Findings
Ordered by consequence. review has a concrete cost when it bites; info is real but depends on your setup. Seen is how common it is across the containers we have measured — reported separately on purpose, because common and harmless are different claims.
reviewNo consent signal in the container (1)
Nothing in this container sets, reads, or gates on a consent state.
WhyThe container itself neither sets a Consent Mode default, holds any tag back for consent, nor references a known consent platform. Either enforcement lives entirely outside GTM — where it cannot be audited from here — or tags fire regardless of what a visitor chose.
CheckIf a consent platform blocks scripts before GTM loads, this is fine — confirm that is actually the case. If not, tags are firing on a choice nobody recorded.
Seenseen in 52.1% of 46,522 containers measured
infoLoads JavaScript from another host (7)
7 pieces of custom code fetch and run JavaScript from another host.
WhyWhatever that host serves executes with full access to the page — it can read the DOM, cookies and form fields. The code is not in this container, so it can change at any time without any change here.
CheckConfirm you recognise every host below and that someone owns the relationship. A host you cannot name is the one to chase.

infoUses browser storage (1)
1 piece of custom code read or write localStorage or sessionStorage.
WhyBrowser storage persists across visits and is not covered by cookie consent tooling, so it is easy to overlook when auditing what you keep on a visitor's device.
CheckConfirm nothing personal is being kept there, and that it is covered by your privacy notice.

Third parties it can reach
Each host is a party that can execute code or receive data in a visitor's browser. Follow one to see who else loads it. More info »

Re-audit
This reading is from a month ago. A container can be republished at any time, and nothing here updates on its own — a fresh read is the only way to know whether it still says this. Running it again replaces this page in place, so the link keeps working.
Put this container under version control. Tagora exports it to a repository you own, so every change arrives as a pull request. How it works »
