Cloudflare Zaraz vs Google Tag Manager
Updated November 2026 · AppBreakup editorial
Cloudflare Zaraz
Tag manager that loads third-party scripts from Cloudflare's edge instead of the visitor's browser.
Google Tag Manager
Free Google tool for adding and managing website and app tracking tags without code changes.
The short answer
Google Tag Manager suits marketing teams on any site who want a free, widely supported way to manage analytics and ad tags, with a large template gallery. Cloudflare Zaraz suits sites already on Cloudflare that want fewer browser scripts, since it runs many tools at Cloudflare's edge and includes consent management. The biggest difference is where tags run: mostly the browser for GTM, Cloudflare's servers for Zaraz.
Cloudflare Zaraz or Google Tag Manager: our take
Both tools let you add analytics tags, ad pixels and other third-party scripts through a dashboard instead of editing site code. Both use triggers and variables, offer preview modes and version history, and let you roll back changes. The difference lies in how tags are loaded and what each needs from your setup.
Google Tag Manager works by adding a container snippet to your site once. You then define tags, triggers and variables, debug them in preview mode, and publish versions. Workspaces, user permissions and environments help marketing and engineering teams work separately, and a large community template gallery covers many third-party tools. The standard version is free for nearly all sites; Tag Manager 360 adds enterprise controls and support through Google Marketing Platform. A server-side container option exists but needs your own paid cloud hosting. Because tags run in the browser by default, a poorly governed container can slow pages and send data to vendors you didn't intend.
Cloudflare Zaraz is built into Cloudflare and runs most tools server-side at Cloudflare's edge, so fewer scripts load in the visitor's browser. It includes a web API for custom events and e-commerce data and built-in consent management with IAB TCF support, which GTM leaves to separate tools. Every Cloudflare account gets 1,000,000 events/month free, with heavier use billed at $5 per extra 1M events/month. It works best when the site is proxied through Cloudflare, has fewer native integrations than GTM's template library, and is harder to debug because browser extensions can't see server-side tools. Cloudflare recommends configuring tags directly in Zaraz rather than loading GTM through it.
Choose Google Tag Manager if your site isn't on Cloudflare, you rely on many third-party tags, or your team already knows the GTM workflow. Choose Zaraz if your site is already proxied through Cloudflare and page speed, fewer browser scripts and built-in consent handling matter more than the widest choice of integrations.
Which should you pick?
Choose Cloudflare Zaraz if…
- Sites already on Cloudflare that want to cut browser-side tag scripts and handle consent in one place.
- Runs many tools server-side, so fewer scripts load in the browser
- One million events a month free on every Cloudflare account
Choose Google Tag Manager if…
- Marketing teams that want to manage analytics and ad tags without waiting on developers
- Free for nearly all sites
- Preview, debug mode and version history for every change
About each app
What is Cloudflare Zaraz?
Cloudflare Zaraz is a tag manager built into Cloudflare. Instead of adding analytics tags, ad pixels and chat widgets as browser scripts, you configure them in the Cloudflare dashboard and Zaraz runs most of them server-side at Cloudflare's edge. The aim is faster pages and more control over what third parties receive. It includes triggers and actions much like Google Tag Manager, a web API for tracking custom events and e-commerce data, variables, a preview mode with version history, and a built-in consent management tool with IAB TCF support. Cloudflare recommends configuring tags directly in Zaraz rather than loading Google Tag Manager through it. It works best on sites already proxied through Cloudflare. Every Cloudflare account gets a monthly allowance of free events, and heavier use is billed per extra million events. It suits sites already on Cloudflare that want fewer browser scripts; teams that rely on a tag not yet supported as a native tool may need custom HTML or their own managed components.
What is Google Tag Manager?
Google Tag Manager lets marketers and analysts deploy tracking tags such as Google Analytics, Google Ads conversions, Meta pixels and other vendor scripts through a web interface instead of editing site code. You install a container snippet once, then define tags, triggers and variables, preview and debug them, and publish versions with rollback. Workspaces, user permissions and environments let marketing and engineering teams work on changes separately. A community template gallery covers many third-party tools, and a server-side container option moves tag processing to your own cloud server for better performance and data control. The standard version is free; Tag Manager 360, sold with Google Marketing Platform, adds enterprise controls and support. It runs in the browser and supports web and mobile apps through Firebase. Badly managed containers can slow sites down and leak data to vendors, so it needs governance.
