Google Data Studio is pretty good for this use case. https://datastudio.google.com/

Thank you for your reply. It seems to me datastudio helps you generate one-off reports? What I am looking for is more of an embedded solution for sellers to log into our dashboard and can slice and dice their data directly on our website.

The reports are interactive and update along with your data, you can slice and drill down as needed. They can also be embedded into your site. https://support.google.com/looker-studio/answer/7450249

You probably want these reports only available to specific sellers, you would be gated by Google auth... so if you're looking for a better embedded solution you may need to find something open source you can self-host.
