Alation Data Intelligence Platform vs DataHub

Alation Data Intelligence Platform brings data context, policies, definitions, and relationships into a shared reference for people, agents, and data applications seeking trusted data. Its Data Catalog uses machine learning to interpret natural-language searches and surface relevant assets, while automated column-level lineage traces relationships from source to destination. ALLIE AI recommends metadata descriptions, and the platform offers agents for documentation, data quality, and data product building. Organizations can create risk and compliance policies through the Data Governance Policy Center. Alation combines metadata with quality metrics and connects to external quality and observability tools through its Open Data Quality Framework. It lists more than 120 connectors, with an SDK for developing additional ones, and provides REST APIs for integrations and bulk transfers of glossaries or documents. Examples include Snowflake, Tableau, AWS Glue, Databricks, MongoDB, and Salesforce; data can also be brought into Excel, Teams, and Slack. Deployment options include on-premises and multi-cloud environments, including Azure. Pricing is on request: the listed plan uses a pool of consumption units whose size is estimated with Alation.

DataHub brings technical metadata, business knowledge, and documentation together for enterprise data and AI agents. It is available as self-hosted Core or as managed DataHub Cloud. Cloud provides natural-language search, an Ask DataHub chat agent, smart ranking, and a hosted MCP server that connects AI tools to its catalog. Its observability tools run automated schema, freshness, volume, and custom quality checks, with AI anomaly detection and incident workflows. Cross-platform, column-level lineage traces data from sources through transformations and AI models to downstream assets. DataHub Cloud has more than 100 pre-built connectors and names Slack, Microsoft Teams, Chrome, and BI tools among its native integrations. Cloud is described as SOC 2 compliant, with role- and attribute-based access controls and an in-VPC execution option for sensitive sources. Cloud availability is described as SLA-backed at 99.5%. DataHub Core is free to deploy, but requires users to handle installation, configuration, upgrades, uptime, and troubleshooting. Cloud pricing depends on data volume, users, and selected capabilities. A Google Cloud offer advertises a 21-day Cloud trial with a dedicated instance and full platform access.
