If you are technical, I would recommend looking at the open-source Python ecosystem to create reports and dashboards. It has amazing analysis and visualization libraries (like Altair and Plotly). We are building an open-source library to create data front-ends like reports and dashboards using Python (https://github.com/datapane/datapane https://github.com/datapane/datapane). You could programmatically create a dashboard for each user and save it as HTML to something like S3. As the dashboards can be pre-rendered and static, they can scaled really heavily if you need.
