Trace, track, and trust
your data & AI.
Automated, column-level lineage stitched across 100+ connectors — helping teams conduct root cause and impact analysis in minutes, make trusted decisions, and deliver context-aware AI that performs reliably in production.
"In just the first few months, Atlan had lineage across systems like our on-prem Oracle databases, BigQuery data warehouse on Google Cloud, and Looker for visualizations."
"Questions about downstream impact used to take allocation of a lot of resources and at least four to six weeks, but [with Atlan] I solved that within 30 minutes, saying 'If you're changing the column name or adding an extra column, this is what it's going to break or impact."
"I have Atlan as the metadata plane across our tech stack. We have one place to define the data, understand what it means, and where it comes from."
See How Your Business, Data, and AI All
Work Together. Instantly.
Automatically map every relationship across your data and AI estate — from business-level data products to column-level details — all stitched into one connected lineage graph.
Column Lineage For Data Engineers & Architects
Atlan auto-stitches column-level lineage across your stack so you can debug faster, design smarter, and trust every model, metric, and migration.
AI Lineage For ML Teams & AI Governance
Follow data, training sets, and models end-to-end for complete visibility into how your AI is trained, deployed, and making decisions.
Data Product & Domain Lineage For Business Teams
See how every metric and data product is built across domains so business teams understand context instantly.
Bring Your Own Lineage For Everything Else
Not everything in your stack comes with a native extractor — and that's fine. Atlan lets you import lineage via CSV, build it visually, publish it via API, or stream it through OpenLineage.
Lineage Context that Meets Humans & AI
Where They Work
Bring lineage into the tools, reviews, and automations your teams already use, so humans and AI agents get the right context exactly when they need it.
Quality Signals for Faster RCA
Atlan surfaces upstream errors and impacted assets directly in lineage so teams can pinpoint issues in minutes, not hours.
Proactive Impact Analysis in GitHub & GitLab
See the full downstream impact of dbt model changes inside your pull requests, giving every developer instant, context-rich code review.
Auto-Propagate Metadata Along Lineage
Tags, glossary terms, and descriptions automatically travel across lineage and sync bi-directionally with tools like Snowflake and Databricks.
AI Access via MCP
Give AI agents and automations direct access to lineage context through Atlan's MCP Server so they can work smarter, safer, and with full awareness.
"With Google DataPlex, lineage only showed part of the story. Our business operates across many systems and we needed complete, enterprise wide lineage. Atlan's platform was more intuitive, delivered on complex end-to-end lineage, and had a strong library of connectors. We also used OpenLineage for Spark jobs to tie operational lineage to our data platform."
