Do not start a new deployment of Amundsen. The project was archived in September 2026 after no releases since August 2024, so it will receive no security fixes or new connectors. Existing users should plan a migration to a maintained open source catalog such as DataHub or OpenMetadata.
Overview
Amundsen is a data discovery and metadata engine that helped analysts and engineers find tables and dashboards, ranked search results by usage, and showed table and column details, owners and previews. It was hosted by the LF AI & Data Foundation, which accepted it as an incubation project in August 2020, and released under the Apache 2.0 licence.
Its architecture is a set of microservices: a Flask and React frontend, a search service backed by Elasticsearch, a metadata service that stores the graph in Neo4j or Apache Atlas (with AWS Neptune and relational stores as further options), and the databuilder ingestion library that can run as a Python script or an Airflow DAG. On 29 September 2026 the repository was archived for inactivity and is now read-only.
Key features
- Search across tables, dashboards and other resources, ranked by usage
- Table and column detail pages with optional column statistics
- Data preview that can integrate with Apache Superset or other tools
- Databuilder ingestion library for warehouses, databases, dbt and dashboards
- Pluggable metadata store: Neo4j, Apache Atlas, AWS Neptune or a relational database
- Airflow integration to schedule metadata ingestion
Integrations and ecosystem
Pros and cons
Pros
- Code remains available under Apache 2.0 for reference or forks
- Simple discovery-focused design with usage-ranked search
- Databuilder patterns are a useful reference for metadata ingestion
Cons
- Archived in September 2026: no maintenance, security fixes or new releases
- No releases since August 2024, so connectors and dependencies are ageing
- Governance features such as glossary, classification and policies are not documented
Pricing
Amundsen was free open source software under the Apache 2.0 licence, and the code remains available. There was no paid edition from the project. Since the repository was archived in September 2026 there are no further releases or fixes, so any deployment now carries the cost of maintaining it yourself.
Pricing checked on the vendor's official page on 7 November 2026. Prices change; confirm before buying.
Who it is best for
Reference only: teams that still run Amundsen and are planning their migration, or engineers studying its ingestion design.
Typical use cases
- Historical: a discovery portal for warehouse tables ranked by query usage
- Planning a migration of existing Amundsen metadata to a maintained catalog
- Studying the databuilder approach to extracting and loading metadata
Who should look elsewhere
- Any new catalog project: choose a maintained catalog such as DataHub or OpenMetadata.
Verdict
Amundsen helped popularise open source data discovery, but it is now an archived project with no releases since 2024. Treat it as history: existing users should move to a maintained catalog, and new teams should not adopt it.
Frequently asked questions
Is Amundsen still maintained?
No. The amundsen-io/amundsen repository was archived on 29 September 2026, and its README says it was archived due to inactivity. The last releases were in 2024.
What should Amundsen users migrate to?
The project names no successor. Maintained open source catalogs with similar discovery features include DataHub and OpenMetadata, both under Apache 2.0.
Can I still download Amundsen?
Yes. The archived repository stays available read-only for historical purposes, but it receives no fixes, so running it in production is at your own risk.
