Looker

Looker is a leading enterprise business intelligence and data exploration platform, now part of Google Cloud, that uses a unique semantic modeling layer called LookML to define business metrics, dimensions, and data relationships in a governed, reusable way. Founded in 2012 and acquired by Google in 2020, Looker serves thousands of data-driven organizations worldwide and has become a preferred platform for engineering-led analytics teams that prioritize data governance and consistency.

LookML (Looker Modeling Language) is the cornerstone of Looker's architecture, providing a Git-versioned, code-based semantic layer where data teams define metrics, dimensions, and business logic once and expose them to all business users as a consistent, governed view of the data. This approach ensures that every user across the organization works with the same definition of key metrics like revenue, customer lifetime value, or active users, eliminating the inconsistency and debate that arise when different teams calculate the same metrics differently.

Looker's Explore interface enables business users to self-serve data analysis by selecting dimensions and measures from the LookML-defined data model without requiring SQL knowledge. Users can filter, pivot, and drill into data with point-and-click interactions, creating custom analyses that respect all the governance rules and data access permissions defined in the LookML model.

Looker Studio (formerly Google Data Studio) provides a free, accessible data visualization and reporting tool that complements Looker's enterprise platform, enabling users to create shareable reports and dashboards from Google Analytics, Google Ads, BigQuery, and hundreds of other data sources through Google's connector ecosystem.

Looker's embedded analytics capabilities enable organizations to build data products and customer-facing analytics into applications, providing white-labeled, branded analytics experiences powered by Looker's governance and query infrastructure. Looker's integration with BigQuery, Vertex AI, and the broader Google Cloud ecosystem makes it a natural choice for organizations that have standardized on Google Cloud for their data infrastructure.
