From my experience with Amundsen, I found it excels at providing a centralized, searchable data catalog that significantly improves data discovery and governance within organizations. Its open source nature allows for customization and integration with various data sources, making it a flexible choice for data teams. However, deploying and maintaining Amundsen requires technical expertise, and its user interface may be less intuitive for non-technical users. Overall, if your organization needs a robust metadata management and data discovery platform without licensing costs, Amundsen delivers solid capabilities supported by an active community.
