Here’s the difference between Superset and Metaphor. The comparison is based on pricing, deployment, business model, and other important factors.
Apache Superset is an open-source software cloud-native application for data exploration and data visualization able to handle data at petabyte scale. The application started as a hack-a-thon project by Maxime Beauchemin while working at Airbnb and entered the Apache Incubator program in 2017.
Metaphor is a search and discovery tool built for data scientists, data engineers, and AI practitioners. It aims to help all organizations better understand and manage their data through the power of the metadata knowledge graph.
