A self-hosted option, free plan and the listed paid-from price add useful comparison points. Netdata, InfluxDB and Dynatrace Kubernetes Monitoring are among the tools shown. Consider the data and retention approach you need, then weigh those requirements against the available deployment and pricing details.
