Alation

Alation is a data catalog platform that uses machine learning to help teams find, understand, and govern their data. It automatically crawls your databases, warehouses, and BI tools, builds a searchable catalogue of tables and dashboards, and learns from how people use data to recommend the most trusted assets. It is designed to make data discovery as easy as a web search.

Key Features

• Machine-learning-powered data catalog
• Automatic discovery across databases and BI tools
• Searchable catalogue with usage-based recommendations
• End-to-end lineage and governance
• AI-generated documentation and tagging

How it works

The platform covers cataloguing, lineage, governance, and collaboration: users can see where data comes from, who uses it, and whether it is trusted, while data stewards manage policies and quality. Its AI features generate documentation, suggest tags, and answer questions about data assets, and it integrates with the major cloud platforms and data tools.

Alation is priced by quote with no public price list and no permanent free plan. It fits mid-size and large organisations that need a governed, searchable catalog. For small teams the cost is hard to justify, and simpler documentation practices may be enough.
