I had this idea while trying out harness.io and its lack of support of flux-like GitOps. You can integrate this api with your CD platform for canary deployments (eg: flux-flagger/Argo) and this would look at your log and metrics data and report abnormal behaviour with your applications.
Looking forward to feedbacks, it seems my last post was flagged because the signup button wasn't visible. We've fixed that, and if there's any other difficulties please comment - we'll fix it asap :)
Note: We currently only support Linkerd, Istio support is coming soon.
