Crabby monitors your websites and APIs and reports metrics to a variety of storage backends (Prometheus, Datadog, Splunk, InfluxDB, etc).

It gives you insight into timings like TTFB, DNS resolution, TLS negotiation, server processing, and content delivery. It also supports chromedp for automated gathering of browser metrics like page render timings.

It's very easy to configure and includes a Helm chart for deployment into K8S.
