Tired of the limitations of Google Data Studio in 2025? You’re not alone. Many businesses are now exploring open-source BI tools that offer more flexibility, self-hosting options, and advanced analytics.
In this blog, we compare Apache Superset, Metabase, and KNIME Analytics Platform to help you find the right solution for dashboards, analytics, and data workflows.
