Mitzu vs. Google Analytics 4 (GA4)

TL;DR

Compare GA4 and Mitzu to find the best analytics tool for your needs, considering features, usability, and privacy. Choosing the right analytics tool can make your team understands user behavior and product performance.

The difference between Mitzu & Google Analytics 4 (GA4)

1. Introduction

Choosing the right analytics tool can make your team understands user behavior and product performance. Mitzu brings analytics straight into your data warehouse, giving you full control over event data and a more privacy-conscious setup.

On the other hand, GA4 (Google Analytics 4) is the go-to for many teams thanks to its easy setup, free access, and tight integration with Google’s marketing tools. It’s built around event-based tracking, making it flexible for websites and apps alike.

In this guide, we break down the key differences, features, data access, and privacy, so you can figure out which one fits your workflow best.

4. Event Tracking & Schema

GA4 via GTM (Google Tag Manager)

javascript// GA4 - Web Tag gtag('event', 'purchase', { value: 23.07, currency: 'USD', product_id: 'A123', method: 'credit_card' });Notes:

  • Event parameters must be pre-registered in GA4 UI for custom dimensions.
  • Advanced event modeling (e.g., arrays, nested objects) is not supported.

Mitzu

Event tracking is available with 3rd-party solutions like Snowplow / RudderStack or similar solutions.

Notes:

  • Schema is user-defined in your data warehouse, enabling full support for nested, high-cardinality data.
  • No need to predefine properties in UI; auto-detected from schema.

5. Data exports

GA4:

  • Export: Set up BigQuery export in property settings.
  • Querying: Only GA4’s BigQuery schema is available, a denormalized event table per day per property.

Sample SQL for extracting recent purchases from BigQuery GA4 export:

SELECT user_pseudo_id, event_timestamp, event_params
FROM `myproject.analytics_123456789.events_*`
WHERE event_name = 'purchase'
  AND _TABLE_SUFFIX BETWEEN '20250701' AND '20250714'
LIMIT 1000;

Limitations: Not real-time (batch export) in free tier, and BigQuery billing applies to queries/storage.Mitzu:Mitzu makes it easy to export insights from your event data:

  • CSV Exports: Download query results directly from the Mitzu UI in CSV format for quick sharing or offline analysis.
  • Data Writebacks (Work in Progress): Mitzu can write data back into your data warehouse by creating Views based on your queries. These views stay synced and always reflect the latest data.
  • Data warehouse connections: Google BigQuery, Snowflake, Amazon Redshift, Databricks, Microsoft Fabric, ClickHouse, Presto, Amazon Athena, PostgreSQL

Mitzu’s exports ensure data stays in your data warehouse with no duplication or movement.

6. Privacy, security & compliance

Mitzu

  • Data remains in your data warehouse or data lakes; no data leaves your data stack.
  • Supports encryption at rest/in transit, column-level masking, customizable access roles, and audit trails.
  • Self-hosting capabilities are present. You can deploy Mitzu in your own cloud environment.

GA4

  • Data stored and processed by Google; subject to Google’s privacy policy and cross-border transfer policies.
  • Supports IP anonymization, IP masking, user deletion API, and built-in consent controls.
  • Customers relying on the free tier have less granularity and flexibility over PII redaction and compliance workflows.
