Looker is Google Cloud's enterprise BI platform with a unique semantic layer approach. It's powerful for organizations that need governed, consistent metrics across teams. But it requires learning LookML (a proprietary modeling language), Git workflows, and significant data team investment before business users can self-serve. Here's the full comparison.

The LookML Problem
Before a business user can ask a question in Looker, a data team must first build LookML models that define your data relationships, metrics, and dimensions. This modeling process takes weeks. And LookML is a proprietary language — your team needs to learn it, maintain it, and version-control it with Git. Sourcetable works immediately: connect your data, ask questions in plain English, get answers.
Git Workflows for Analytics
Looker's LookML models are stored in Git repositories. This is a feature for data engineers who value version control. For business analysts and financial teams, it's an unfamiliar workflow that adds friction. Sourcetable doesn't require any code repository — your analysis lives in the platform.
Google Cloud Lock-In
Looker is optimized for Google Cloud, particularly BigQuery. While it supports other data sources, the best experience is in the Google ecosystem. Sourcetable is cloud-agnostic — we connect to any data source through our 500+ API connectors without vendor lock-in.
