About GTM & CMP Helper
GTM & CMP Helper - The companion for web analysts and developers
GTM & CMP Helper (formerly "Insert GTM" / "GTM Helper") is a Chrome extension that simplifies debugging Google Tag Manager containers and managing Consent Management Platforms (CMPs).
CORE FEATURES:
1. Intelligent CMP Reset
Reset consent status with just one click. The extension automatically detects common CMPs (such as Cookiebot, Usercentrics, OneTrust, Borlabs, CMP19, and many more) and specifically deletes the associated cookies and storage entries. Ideal for testing consent banner logic without manually clearing cookies.
2. GTM Container Injection
Inject any GTM container code (GTM-XXXXXX) into any website. Test new tracking setups in live environments before they are implemented in the source code.
- Supports GTM Environments (gtm_auth & gtm_preview).
- GA4 Debugging: Automatically activates GA4 DebugView by passing preview tokens – without needing the official Tag Assistant.
- Flexible positioning in <head> or <body>.
3. Google Tag & Container Detection
Automatically detects Google tags loaded on the current page — always on, no configuration, no extra permissions. Classifies the load method — standard (googletagmanager.com), first-party (server-side GTM / Google Tag Gateway), custom path, or base64 tunnel.
Container count on the toolbar badge, a "Detected Google tags & containers" popup section (ID · method · host), and a console log per new detection.
4. dataLayer Tools
Send dataLayer push events or execute custom JavaScript code on the current page. Perfect for quick testing of event handlers.
5. GTM Workspace Integration
When working in the GTM interface, the Helper detects this and provides a direct link to the Analytrix GTM Checkup to verify your container for best practices.
6. GTM Interface Comfort
- Submit dialog warning: colors the submit button orange whenever the selected action only creates a version instead of publishing.
- Pending changes highlighted: on the overview page, the workspace header is tinted as soon as anything is waiting to be published — three small counters are easy to miss.
- Pinned navigation: navigation stays visible while scrolling long lists instead of scrolling out of view.
- Pinnable search bars: a toggle in the title bar of tag, trigger, and custom variable lists keeps title, search, and buttons at the top while scrolling.
- Workspace search on Alt+S (default hotkey, configurable): the search in the header is one keystroke away, however far you have scrolled — the page jumps back to the top, the cursor lands in the field, and a term already there is selected. While a dialog is open the key stays inert and belongs to the browser.
- Section switching on Alt+1, Alt+2, Alt+3 ((hotkeys configurable): tags, triggers, and variables open straight from the keyboard, with the menu carrying the selection along.
- Sorting for parameter tables: lookup tables, event parameters, and comparable key/value lists can be sorted alphabetically in both directions — by input or output column. A control inserts an empty row below the current one, where appending at the end is not enough.
- Remembered list state: the sort order of tag, trigger, and variable lists survives a section change instead of falling back to name-ascending. Search terms optionally do too, for as long as the tab stays open.
- Clear origin: every control the extension adds names itself in its tooltip, so it stays apparent which extension a button belongs to.
- Hide built-in variables: a switch permanently collapses the rarely needed list so the user-defined variables are reachable without scrolling.
- Edit variables straight from input fields: when a field of a tag or trigger references a {{variable}}, a chip appears below it. One click opens that variable’s definition directly above the tag, so closing it puts you back where you were instead of in the variable list.
- Everything switchable: each of these features can be turned off on its own — or all at once — in the popup. All on by default, except remembering search terms — that one hides rows, so it ships off.
DESIGN & USABILITY:
- Dark Mode by default (with Light Mode option).
- Available in English and German.

CHANGELOG
---------------------
v3.8
- Tags, triggers, and variables open from the keyboard: Alt+1, Alt+2, Alt+3.
- All four keyboard shortcuts can be chosen freely in the popup.
- Detected tag and container IDs are copied to the clipboard with one click.
v3.7
- Pending changes are highlighted in the workspace overview.
- Lists keep their state across section changes: the chosen sort order always, the search term optionally (off by default, since it hides rows).
- Insert a row below in parameter tables, for lists where the order carries meaning.
- Workspace search on Alt+S: one keystroke scrolls back to the top and puts the cursor in the search field.
v3.6
- Edit variables straight from input fields: a chip under any field that references a {{variable}} opens its definition directly above the tag; closing it returns you to your work instead of the variable list.
- Reworked popup interface.
- All GTM interface features can be switched off individually (or all at once)
v3.5
- GTM interface improvements: permanently visible section navigation, optionally pinned title and search bar in the tag, trigger, and custom variable lists, alphabetical sorting for parameter tables (lookup tables, event parameters, custom templates...), and a switch to hide built-in variables.
v3.4
- the CMP reset now knows about 130 CMPs (previously 70+). h/t to Joachim Nickel who kindly provided a list of CMPs that was extracted from his tool "exatics".
v3.3
- New GTM submit-dialog warning: a CSS-only hint colors the submit button orange and tints the selected "Create Version" option whenever the chosen action only creates a version instead of publishing in GTM.
v3.2
- fixed timing problem in "Clear Consent" function: As this variant deletes all known consent cookies - ins…
