To give an opinionated position regarding Amundsen:

Amundsen is a great open source project with many cool ideas. However, we found that the experience on Snowflake was quite shallow and much more insights and context on data assets are possible. E.g. data profiles, lineage or usage information are not readily available in Amundsen. You can customize and extend Amundsen to do more, but most data teams should build and innovate in other areas closer to the business. ;) Most companies use Snowflake over the Apache Spark open source stack exactly because of that.
