Better Uptime vs OpenTelemetry

Better Uptime (now part of Better Stack) is a website and infrastructure monitoring service that checks uptime every 30 seconds from multiple global locations. It provides incident management, on-call scheduling, and public status pages.

OpenTelemetry is Vendor-neutral open-source framework for generating, collecting, and exporting telemetry data including traces, metrics, and logs.. It is available under a free model. This tool falls under the monitoring category.
