2. Pioneers of the active metadata category

Active metadata is the key to preventing enterprise data catalogs from becoming expensive shelfware. Atlan leads the way as the only active metadata platform, pioneering this critical category.

Atlan activates metadata by connecting context, automation, and recommendations into everyday workflows across your stack.

This unlocks automation and enables powerful programmatic use cases, ensuring your catalog is ready for modern concepts like data fabric and data mesh.

Top use cases include:

• Cost optimization through:
  • Dynamic data pipeline optimization, reducing unnecessary data processing
  • Cleaning up the data landscape by removing stale, unused, or duplicate assets
• Enhancing BI tools with enriched metadata to improve user experience
• Defining access control policies at scale
• Automatically assigning freshness statuses to data assets

3. DIY setup in weeks, not months, leading to faster ROI

When you invest in a data catalog, speed matters—you need it operational in weeks, not months.

Alation deployments commonly require months of configuration, stewardship, and professional services. Atlan delivers value in weeks through a DIY setup, native connectors, automated metadata ingestion, and prebuilt workflows.

Many reviewers on G2 consistently highlight Atlan’s ease of setup when compared to Alation, making it the smarter, more efficient choice.

As a result, data teams commonly witnessed 10X faster rollout and faster ROI (within weeks) when using Atlan, as compared to legacy tools like Alation.

4. A smart, intuitive UX designed for broad adoption (90%+ active usage)

Your data catalog is as good as the data that’s cataloged in it. Adoption and usage are thus crucial to drive value from an enterprise data catalog tool.

Given the diverse nature of data consumers and producers that exist in an enterprise, your data catalog must be able to handle the diversity and granularity of modern data and metadata.

Diversity in data teams, tools, assets, and use cases requires a tool that can handle them to drive adoption. Image by Atlan.

While Alation’s legacy UX is optimized for stewards and analysts, Atlan offers personalized, context-rich experiences for engineers, analysts, ML teams, and business users—leading to 90%+ adoption within 90 days.

“After taking a look at the best catalogs on the market, I chose Atlan, and I would choose Atlan again if I had to. It’s the best UX, best experience, and best adoption.” - Otávio Leite Bastos, Global Governance Lead, Contentsquare

5. Embedded context and collaboration that makes your work flow

Where Alation requires users to switch into the catalog, Atlan brings context to their workflow.

Atlan offers personalized experiences, bidirectional metadata sync with source systems like Snowflake and Databricks, and embedded collaboration for uninterrupted, context-aware work.

Here’s what this embedded context and collaboration look like:

• Metadata in BI tools
• Lineage in GitHub/GitLab pull requests
• Quality signals in dashboards
• Definitions and owners inside notebooks
• Governance signals inside Snowflake, Databricks and other modern data stack tools

This is a major driver of Atlan’s industry-leading adoption rates.

6. An open, interoperable metadata context plane (and not a closed catalog)

Unlike Alation’s legacy setup, Atlan’s open architecture delivers:

• Open metadata lakehouse to unify context and future-proof your data stack
• Bidirectional metadata sync with Snowflake, Databricks, Looker, Tableau, Power BI, Airflow, dbt, and more
• Endless extensibility with numerous connectors and open APIs
• App framework to build AI-native apps on Atlan

This is critical for cloud-native, multi-engine, and AI-driven data estates, and that’s why Atlan is a top Alation competitor for future-forward enterprises.

7. Data Quality Studio to keep bad data out of your business

Atlan integrates with upstream data quality tools, and combines discovery, governance, and quality in a single control plane. This provides a unified, trusted view of data health.

You can embed data quality signals into contracts, AI guardrails, and a 360° reporting hub, ensuring that your data is fit for purpose and AI ready.

8. Superior, future-forward data and AI governance

Alation relies more on manual stewardship, which can cause bottlenecks.

Atlan offers superior governance and policy automation, with tag propagation across lineage paths and embedded governance signals inside warehouses, notebooks, BI tools, and more.

Moreover, Atlan’s AI governance drives your AI initiatives forward while ensuring trust and transparency with centralized AI asset management and end-to-end data flow mapping across the AI lifecycle, and more.

9. Dedicated customer success for mission-critical outcomes

A data catalog is valuable only when:

1. Most of your favorite data tools connect to it
2. Most of your data operations can be managed through it
3. Most of your data users actively use it

Alation requires heavier training and manual stewardship programs.

With Atlan, you get a partner, not a vendor, committed to ensuring your data catalog aligns with your goals and delivers measurable impact.

Atlan’s customer success team, including dedicated Customer Success Managers (CSMs) and Customer Solution Architects (CSAs), collaborates with organizations to drive key data initiatives.

In addition, Atlan empowers its customers through significant investments in data governance and enablement programs, such as Atlan University, DataOps leadership programs and customer-led masterclasses, to foster continuous growth and innovation.

10. Atlan is built for the AI era

Legacy tools like Alation merely catalog data. Atlan activates it to drive innovation, automate governance, and accelerate insight where teams work.

With Atlan, future-forward enterprises get:

• An AI-ready metadata foundation
• App framework to build AI-native apps on Atlan–the context OS for AI
• Automated trust signals for AI agents & copilots
• Lineage-driven explainability for data products, business domains, AI models, etc.
• Policy enforcement integrated across the lifecycle

That’s why modern enterprises like Mastercard, North, Elastic, Unilever, Yape, and Autodesk choose Atlan as their data + AI control plane.

Real stories, real customers: Why modern enterprises chose Atlan for cataloging and governance

From Manual Documentation to Automated Discovery: How Autodesk Did It

“We use a combination of a data lake and a data warehouse. Our data warehouse is Snowflake, the data lake is AWS, and of course, all the technology sits on top of the lake and warehouse to run transformations, queries, and analytics. We needed something that could help bridge the [context] gap. Atlan is the layer that brings a lot of the metadata that publishers provide to the consumers, and it’s where consumers can discover and use the data they need. Autodesk scaled data collaboration across 60 teams by building a data mesh on Snowflake with Atlan. Their Analytics Data Platform now empowers domain teams to publish and govern their own data while maintaining centralized visibility and standards.”
