What are some alternatives to Amundsen?
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. So the question on this page is no longer whether Amundsen is good enough. It is where you move. For a maintained open-source catalog, start with DataHub or OpenMetadata.
Amundsen was an open-source data discovery platform and metadata engine built by the Lyft engineering team.
Introduced and open-sourced in 2019 for adoption outside of Lyft, the platform was initially built to improve the productivity of engineers, data scientists, and analysts at the ride-hailing app.
Adoption inside Lyft ran high, and the project drew an open-source community of ~100 contributors and 39 organizations before activity dried up.
If you run Amundsen today, or you were about to stand it up, these are the projects to look at instead.

Evaluating open source data catalog tools
One of the crucial steps in enabling a collaborative and efficient data culture in your organization is deploying a data catalog software. Discovering the right one for your organization requires answering many different questions — all at once.
- Will this platform support all our primary use cases?
- Will it still work if our data stack changes?
- Will our users feel comfortable using it?
- Should we build it or buy it?
- How do we justify the money we’re asking for?
We know thinking about all of that can be overwhelming. It helps to have a framework to objectively evaluate. Here’s how we could help:
