Cloudflare Zaraz

Cloudflare Zaraz is a server-side tag-management layer for websites that shifts many third-party tools to Cloudflare’s edge. It is a strong fit for teams coordinating analytics, advertising, chatbots, embeds, or marketing automation around specific events, especially when page performance matters. The free allocation lowers the barrier to entry, while growing sites must watch event volume and take ownership of consent configuration.

Overview

Zaraz centralizes third-party tools instead of leaving each script to load independently in the browser. Its supported categories include analytics, advertising, marketing automation, recruiting, embeds, and customer data platforms, making it useful for sites with a varied marketing stack. Offloading processing to Cloudflare’s edge is intended to improve speed and security, so the product is best viewed as an operational layer for web tools rather than an analytics-reporting suite.

It can also serve domains that are not otherwise proxied through Cloudflare, but doing so requires a separate proxied domain or subdomain to deliver the Zaraz script. That requirement is manageable for an organization already using Cloudflare, and an extra deployment step for everyone else.

Key features

• Broad tool coverage: Ready-made support spans measurement, advertising, recruiting, embeds, marketing automation, and customer data platforms. For tools outside those categories, Custom HTML, Custom Image, and HTTP Request integrations provide practical escape routes, although custom integrations demand more configuration care than a supported connector.
• Event-driven loading: The client-side Web API sends events and data that can create triggers and launch tools when they are needed. This helps teams avoid treating every tag as permanently active and gives event-aware control over marketing and measurement activity.
• Consent controls: A configurable consent modal can restrict tools to purposes a visitor has accepted. GDPR compliance still depends on the site owner assigning each tool to the appropriate purpose, so Zaraz supplies a control surface rather than removing that governance responsibility.
• Custom managed components: Custom Managed Components are converted into Cloudflare Workers in the user’s account, extending the platform beyond its standard integrations. They do not support manager.registerEmbed, manager.registerWidget, manager.proxy, or manager.serve, which can rule out component designs that rely on those methods.
• Server-side operation and history: Zaraz supports server-side tagging and version history, useful for keeping changes organized and reducing dependence on browser-loaded scripts. Sending Zaraz event logs to external storage through Logpush is restricted to Enterprise settings, however.

Pricing

Zaraz Free — 0.00 USD: The free plan provides a monthly allocation of 1,000,000 Zaraz Events per Cloudflare account. It suits smaller sites, pilots, and teams that can keep usage below the account-wide ceiling without enabling paid billing.

Zaraz Paid — $5 a month: Each additional 1,000,000 Zaraz Events costs $5 per month. Additional event usage is billed on that basis, and all features and tools are available on all accounts. This is a straightforward growth path, but event-heavy sites should budget for usage rather than assume a fixed subscription price.

Without paid usage billing, exceeding 1,000,000 events in a month disables Zaraz until the next billing cycle. That hard stop makes monitoring essential for production sites where tags support advertising, conversion measurement, or customer communications.

Platforms

Zaraz is available through an API and on the web, supporting websites and Cloudflare-proxied domains. Its deployment model is particularly aligned with web properties already routed through Cloudflare.

Who it's for

Choose Zaraz if your website runs several third-party scripts and you want centralized, event-triggered control with edge-based processing. It is especially relevant to teams managing analytics, advertising pixels, chatbots, embeds, or marketing automation that need consent-aware loading. It is a weaker fit if you mainly need a standalone analytics product, require the unsupported custom-component methods, or cannot tolerate service interruption after crossing the free event ceiling.

Pros and cons

Pros

• Moves supported third-party tools to Cloudflare’s edge, targeting better speed and security.
• Provides a 1,000,000-event monthly free allocation and usage-based paid expansion.
• Combines event triggers, consent gating, server-side tagging, and version history.
• Custom HTML, Custom Image, and HTTP Request options cover tools without native support.

Cons

• The free account-wide cap can disable Zaraz for the remainder of a cycle when paid billing is off.
• Consent-purpose assignment for GDPR remains the site owner’s responsibility.
• Custom Managed Components omit four manager methods, limiting some implementations.
• External Logpush storage for Zaraz event logs is Enterprise-only.

Verdict

Cloudflare Zaraz is a sensible choice for website teams that need one place to coordinate diverse third-party tools, trigger them selectively, and keep a million monthly events within a free allowance. Choose it for edge-based, consent-aware tag operations; look elsewhere if your traffic makes the event ceiling risky, your custom components need unsupported methods, or your priority is analytics reporting rather than tag orchestration.
