Here’s the difference between Tellery and Superset. The comparison is based on pricing, deployment, business model, and other important factors.
Tellery allows you abstract essential data transformation/business logic, and reuse it in future contexts through metrics. Metrics are maintainable and shareable data models across dashboards and reports. They are defined consistently and always up to date. To deliver better value of the metrics, Tellery comes with a bucket of building blocks and rich text styling features. Want a real-time campaign-oriented dashboard? A feature-specific analysis? An anomalies investigation? You can tailor it to your need to unlock the value of data.
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.
