Mitzu dashboards
Dashboards are fully customizable with drag-and-drop, no-code interfaces with auto-generated SQL. It is embeddable in Notion or Miro, and exportable as needed. Real-time, always powered by live warehouse data, results no extracts, no lag.
Posthog dashboards
Dashboards are interactive and modular, with support for visual builders and code-based customization. Technical users can build and share custom dashboards; non-technical users benefit from templates and guided workflows.
4. Event Tracking & Schema
Mitzu
Event tracking is available with 3rd-party solutions like Snowplow / RudderStack or similar solutions.
Notes:
- Schema is user-defined in your warehouse, enabling full support for nested, high-cardinality data.
- No need to predefine properties in UI; auto-detected from schema.
Posthog
- Provides instant autocapture on web/app events with a lightweight JS SDK or backend libraries.
- Users can add custom events and retroactively define event labels ("actions") through the UI.
- Event structure tends to be flatter; while extra properties can be attached, deep warehouse-level enrichment is not automated.
- Schema modifications and data modeling are limited
- Developers can send events via API or SDK and edit tracked properties post-factum
5. Data exports
Mitzu
Mitzu’s exports ensure data stays in your data warehouse with no duplication or movement.
- 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, Starburst, Amazon Athena, PostgreSQL
Posthog
- Provides exports through the UI, API endpoints, and direct integrations.
- Data can be exported as CSV, via plugins, or streamed to third-party destinations.
- Not natively coupled to data warehouses, but supports custom integrations for export/import (e.g., S3, BigQuery plugins).
- More reliant on plugin/API workflows; not all exports are in real-time at large scale.
6. Privacy, security & compliance
Mitzu
- Data remains in your data warehouse or data lakes, therefore, 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.
- Designed for strictest requirements in healthcare, fintech, gaming and heavily regulated data teams.
PostHog
- Open source and can be fully self-hosted, you can operate on their own infra to satisfy compliance.
- Major security certifications (e.g., SOC 2).
- Adopts industry standards for event retention, audit logging, authentication, and GDPR/HIPAA compliance.
- Privacy controls depend on how the platform is hosted, public cloud vs. private/on-prem.
