Cloudflare Zaraz vs MetaRouter Server-Side Tag Management

Cloudflare Zaraz lets website owners manage third-party tools and run them through Cloudflare’s edge, with the stated aim of improving site speed and security. Its supported categories include analytics, advertising, marketing automation, recruiting, embeds, and customer data platforms. For other tools, custom integrations include Custom HTML, Custom Image, and HTTP Request. A client-side Web API can send events and data used to create triggers and launch tools. Zaraz also provides a configurable consent modal that can load tools according to purposes users have agreed to; users remain responsible for assigning tools to purposes when needed for GDPR compliance. The free plan includes 1,000,000 Zaraz Events per Cloudflare account each month. Additional usage costs $5 a month for each additional 1,000,000 events, and all features and tools are available on all accounts. Without paid usage billing, Zaraz is disabled until the next billing cycle if monthly events exceed 1,000,000. It can serve its script on a domain not proxied through Cloudflare if a separate proxied domain or subdomain is set up for the script. Zaraz is available through web and API platforms.

MetaRouter Server-Side Tag Management collects first-party customer data on a server and routes it to advertising, marketing, and analytics destinations. Its single code library handles page data, behavioral data, identity data, and third-party identifier resolution. Before sending events onward, customers can map, transform, and filter incoming parameters. Sync Injector adds addressable cookie-based IDs and URL decorators to support third-party identity resolution. Listed integrations include Google Analytics, Google Ads, Meta, Amazon Redshift, BigQuery, Braze, Salesforce, and Snowflake. Organizations can deploy on their own Google Cloud, AWS, or Azure environment, or use a single-tenant MetaRouter-hosted environment on those clouds. Self-hosted customers pay infrastructure resource costs estimated from expected event volume and integrations. The product supports websites, server-side tagging, and consent management. Pricing is on request under a custom enterprise plan scoped to use cases, event volume, and infrastructure footprint, with no per-user or per-profile fees.
