Hi! I support a SaaS business. Our core product is a single-tenant enterprise application, so each customer is deployed in its own environment. Deployments are completely automated (Ansible, Kubernetes, etc), and now we'd like to take the next step and allow customers to self-manage by exposing a customer "control panel" that integrates our existing automation and payments with a UI that they can operate. Think: "single click apps" on DigitalOcean.

I'm looking for recommendations for FOSS products that fit somewhere between customer and infrastructure; something intended to be more customer-facing than, say, Portainer or Yacht.
