Vanilla JS will come pretty soon, though we can't provide the "adapt to your design system" feature there. We have more features to get you started quickly than both Supabase and Supertokens on the frontend, but are (currently) missing some enterprise features on the backend in comparison to those (specifically 2FA and SSO/SAML).
Eventually, we want to catch up on the enterprise features but maintain the simple setup for the frontend.
