What are some alternatives to Apache Atlas?
Apache Atlas is a popular open-source data catalog software. It enjoys an active community of committers from businesses like Hortonworks, Aetna, Merck, IBM, and Target. Contributors to the project who keep developing and expanding it year on year.
Yet, it can be a bit clunky to use and navigate. Here are Apache Atlas alternatives to consider while researching for an open-source data catalog tool that is best suited to your organizational needs.
3 open source Apache Atlas alternatives
- LinkedIn’s DataHub
- Netflix’s Metacat
- Lyft’s Amundsen (archived September 2026)
Amundsen ranked first here for years. It now ranks last because the project was archived in September 2026, and a read-only repo fails the maintenance test the other two pass.

DataHub
DataHub is an open-source metadata search and discovery tool that was built at LinkedIn.
DataHub, which was open-sourced in 2020, is actually LinkedIn’s second attempt at solving data discovery and cataloging as a problem. Their first attempt was WhereHows in 2016.
DataHub has the following main capabilities:
- Ease of data discovery via searching and browsing a data asset
- Understanding data with context
- Automated metadata ingestion from diverse data sources

Metacat is an open source federated metadata management platform that powers data discovery and metadata interoperability at Netflix.
It is used to catalog, discover, process, and manage data. It forms a single access layer for data residing across the diverse mesh of data sources operating at Netflix.
Metacat is primarily known for the following capabilities:
- Common abstraction layer
- Provision for user and business defined metadata storage
- Easy data discovery
- Notifications related to data changes

Amundsen (archived)
Status, September 2026: Amundsen is archived. The Amundsen repository carries the notice “Due to inactivity, this project was archived in September 2026. The contents will remain available for historical purposes.” GitHub records the archive on September 10, 2026. The code stays available under Apache-2.0, but the repo is read-only: no new releases, no security patches, no maintainer review of issues or pull requests. Teams replacing Apache Atlas today should choose DataHub or OpenMetadata instead.
Built by the Lyft engineering team, Amundsen was an open source data discovery platform and metadata engine.
It was introduced to the world in April 2019 and open sourced later that year for adoption outside Lyft. It was primarily built to improve the productivity of data scientists, engineers, and analysts at Lyft.
Adoption inside Lyft ran high, and the open-source community grew to 750+ members and 37+ organizations using it officially before the project went quiet.
What teams used Amundsen for:
- Simple text search powering easy data discovery
- More context on data with automated and curated metadata
- Ease of sharing context with others
- Learning more about data usage

Open-source tools like Apache Atlas, DataHub, and OpenMetadata require self-hosting — your team manages the infrastructure, builds the connectors, and maintains the system. Managed platforms like Atlan handle infrastructure, provide pre-built connectors across cloud-native sources, and add capabilities that most self-hosted tools lack: automated governance workflows, AI-generated metadata enrichment, and protocol-native delivery to AI agents via MCP. The trade-off is operational control versus time-to-value. Teams that have spent months building Atlas integrations for Snowflake or BigQuery understand this trade-off.
How organizations use Atlan
The Forrester Wave for Data Catalogs (2025) positioned Atlan as the market leader. Atlan is also a Leader in the Gartner Magic Quadrant for Metadata Management (2025, 2026) and rated #1 in Data Catalog and Data Governance on G2. The Forrester comparison evaluated 24 aspects of cataloging across three criteria:
- Automatic cataloging of the entire technology, data, and AI ecosystem
- Enabling the data ecosystem AI and automation first
- Prioritizing data democratization and self-service
These criteria made Atlan the ideal choice for a major audio content platform, where the data ecosystem was centered around Snowflake. The platform sought a “one-stop shop for governance and discovery,” and Atlan played a crucial role in ensuring their data was “understandable, reliable, high-quality, and discoverable.”
For another organization, Aliaxis, which also uses Snowflake as their core data platform, Atlan served as “a bridge” between various tools and technologies across the data ecosystem. With its organization-wide business glossary, Atlan became the go-to platform for finding, accessing, and using data. It also significantly reduced the time spent by data engineers and analysts on pipeline debugging and troubleshooting.
For organizations deploying AI agents, Atlan goes further. The same metadata graph that powers catalog and governance also feeds the Context Layer — where Context Agents turn raw metadata into business context, generating descriptions, quality signals, term mappings, and semantic relationships that manual documentation teams cannot produce at enterprise scale. Agents access this context through MCP endpoints, SQL interfaces, and direct API access before acting on enterprise data.
Tide’s Story of GDPR Compliance: Embedding Privacy into Automated Processes
- Tide, a UK-based digital bank with nearly 500,000 small business customers, sought to improve their compliance with GDPR’s Right to Erasure, commonly known as the “Right to be forgotten”.
- After adopting Atlan as their metadata platform, Tide’s data and legal teams collaborated to define personally identifiable information in order to propagate those definitions and tags across their data estate.
- Tide used Atlan Playbooks (rule-based bulk automations) to automatically identify, tag, and secure personal data, turning a 50-day manual process into mere hours of work.

FAQs about Apache Atlas Alternatives
1. What are the best alternatives to Apache Atlas for data governance?
DataHub, OpenMetadata, and Metacat are the alternatives to Apache Atlas worth shortlisting. Each covers a different part of governance and discovery. Amundsen was archived in September 2026, so its repo is read-only and it no longer belongs on a list of tools to deploy.
2. How do Apache Atlas alternatives compare in terms of features and usability?
DataHub and OpenMetadata ship cleaner interfaces and wider connector coverage than Apache Atlas, which makes them easier for analysts to pick up. Amundsen was known for the same ease of use, but the project was archived in September 2026 and gets no further updates.
3. What are the key benefits of using alternatives to Apache Atlas?
Alternatives to Apache Atlas often offer improved usability, better integration capabilities, and tailored features for specific industries. They can enhance data governance and streamline data management processes.
4. Which Apache Atlas alternatives are most suitable for small to medium-sized businesses?
DataHub and OpenMetadata suit small to medium-sized businesses. They provide essential data discovery features without the complexity often associated with larger platforms like Apache Atlas. Amundsen used to fill that role, but it was archived in September 2026, so a new deployment would run unmaintained code.
5. How do Apache Atlas alternatives handle data lineage and metadata management?
Most Apache Atlas alternatives, including DataHub and Metacat, offer robust metadata management and data lineage capabilities. They ensure that users can track data changes and maintain data integrity effectively.
6. Are there any open-source alternatives to Apache Atlas that I should consider?
Yes. DataHub, OpenMetadata, and Metacat are open source and still maintained, and they cover data discovery and management for teams looking for cost-effective options. Amundsen is open source too, under Apache-2.0, but the project was archived in September 2026: read the code, do not plan a deployment around it.
