Stape GTM Helper is a free Chrome extension designed to streamline Google Tag Manager (GTM) debugging. It enhances the GTM preview mode by adding features that improve navigation and error identification. One standout feature is tag type and status coloring, which uses colors and logos to differentiate between platforms like Meta, GA4, and Google Ads. This makes it easier to spot failed requests at a glance. Another helpful tool is the Entities Filter, allowing users to focus on specific tags or variables, which speeds up the debugging process. The extension also includes a JSON Formatter for better readability of incoming and outgoing JSON requests, and a Request URL Formatter that organizes URL query parameters into structured tables or JSON format. For those using server-side GTM, the extension shows the consent status directly in the preview, providing clarity on whether consent has been granted or denied. Designed for marketing agencies, developers, and analysts, Stape GTM Helper aims to make GTM debugging more efficient and user-friendly. The extension is lightweight at 90.75 KiB and was last updated on January 5, 2026.
