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.
2. Generic comparison
| Feature | Mitzu | GA4 |
|---|---|---|
| Event Tracking Model | Event-based; event schema equals table schemas; supports unlimited custom props & join-based enrichment. | Event-based; custom events allowed, but limited by structure and parameter caps. |
| Data Retention | Unlimited (based on warehouse storage) | 14 months (free), extended with GA4 360 |
| Real-time Reporting | Instant, unsampled, warehouse-powered | Real-time, but limited and aggregated |

GA4 Dashboards
Feature pre-set visualizations, attribution panels, and standard Ecommerce/Acquisition/Realtime reports.

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.
7. Use cases & suitability
| Scenario / Need | GA4 | Mitzu |
|---|---|---|
| Small website/blog | Easy, free, quick setup. UI oriented for marketers. | Overkill; better suited for large datasets. |
| Large SaaS or B2B product | Lacks advanced journey/retention/product analytics. | Built for product analytics, advanced cohort analytics, funnels, and retention. |
| High data cardinality/complexity | Limits on parameters, sampling at scale. | Unlimited complexity, no sampling, full SQL flexibility. |
| Advanced BI/ML integration | Possible with BigQuery, but batch/lagged; paid limitations. | Native, use the same warehouse for BI, ETL, CDP or reverse ETL. |
| Advanced inbuilt BI capabilities | Basic built-in reports; advanced requires BigQuery. | Full inbuilt BI; self-serve and code-based analytics unified. |
| Privacy & compliance focus | Some anonymization; limited local options. | Full isolation; no data sharing; 100% privacy and compliance friendly. |
| Data team with SQL skills | Only via BigQuery export; not real-time. | SQL-first; ad hoc, no-code and code-based queries. |
| Marketing attribution | Strong with Google Ads; limited customization. | Custom models; not ad-centric, but broader view. |
| Non-technical stakeholder access | Prebuilt dashboards easy for basic overview. | Drag-and-drop, no-code UI for custom analysis. Self-service. |
| Long-term event history | 14mo cap in GA4; must export/archive. | Retention limited only by warehouse scale/costs. |
