Observability and deployment management for small SaaS products

I am exploring for deployment management(docker swarm/kubernetes/others), observability and dashboarding for applications that have only a few ( under 10 ) (micro)services running.

I have looked at Amazon, DataDog, Portainer, Kubernetes Dashboard, and a bunch of others. I not found a ‘SaaS’ offering that will allow me to do these. There are a bunch of CI/CD, tools, but then they dont seem to do good customer facing dashboards.

Any recommendations?
