9
Path Exploration / User Flows
The pathing tool visualizes the sequential flow of users through a site or app, starting from a specific event or working backward from a conversion. The Paths tool visualizes organic user navigation, allowing teams to map journeys based on pageviews, custom events, or screen names.
9
Cohort & Retention Analysis
The cohort tool enables teams to group users by shared characteristics (like acquisition date) to track retention, engagement, and conversion decay over time. Enables cohort and retention analysis by grouping users through complex behavioral triggers over custom timeframes.
9
Attribution Modeling
Uses data-driven models to distribute conversion credit across marketing touchpoints.
9
Raw Data Export (BigQuery/S3)
Exports complete, unsampled event data via native integration with Google BigQuery at no additional cost. The Data Pipelines feature allows seamless, automated export of raw, unsampled event data to external warehouses like BigQuery or S3.
9
Native SDKs
Mobile app measurement is supported through dedicated Firebase SDKs for both iOS and Android environments. It features automatic logging for standard app interactions alongside the ability to define custom events. Open-source SDKs for web, mobile, and backend, integrated with feature flags and session recording.
8
Data Sampling Control
To maintain platform speed during complex queries on large datasets, the system applies data sampling, estimating results based on a subset of data.
8
Proxy Deployment / Custom Domain

Custom Data Models
Custom data modeling operates entirely on an event-driven schema, allowing for unlimited custom event definitions rather than relying on rigid session tracking.
7
Automated Schema Management
The Data Management feature provides a centralized dictionary to verify, annotate, and govern custom events and properties across the organization.
7
Built-in A/B Testing
The experimentation framework uniquely integrates A/B testing and multivariate experimentation directly into the analytics platform alongside feature flags and session replay.

Bot Filtering
Automated filtering actively excludes traffic originating from known web spiders and bots based on internally maintained lists. This feature operates entirely in the background and cannot be customized or disabled by the user.
