We have components like and that automatically adapt to whatever theme & design system you're using. Check the blog post to see the example with Radix UI and Joy UI. Also, there's an admin dashboard for monitoring and editing accounts. Stack is 100% AGPL/MIT-licensed, so you can self-host it. Cheers!
