For a use case like this, you might want to consider opensource StyleBI. It’s designed to handle large-scale, multi-tenant analytics with high cardinality efficiently, and you can embed dashboards directly into your web app. Because it’s serverless and elastic, it can scale automatically with your data volume without incurring the same costs as continuously sampling millions of traces or sending high-cardinality metrics to Datadog. StyleBI also supports connecting directly to common data sources and applying filters like user location or application usage, making it easier to build the insights you need without overspending.
