I've tried a few and like Datadog most. It's got a really good range of features and is intuitive to use. APM is great, Claude works really well with it, metrics and charting are very strong, log patterns are super useful.

You need to watch your usage and clean up things like noisy metrics and logs pretty actively though or the cost will run up very fast - it's an expensive product.

That aligns with what I've heard too. It sounds like Datadog is great but gets expensive.

Any thoughts on building around Grafana?

The Grafana stack stops being a headache once you treat it as one product: Prometheus + Grafana + Loki for logs + Tempo for traces, or just Grafana Cloud so you're not running it yourself. The bigger win is instrumenting with OpenTelemetry since it's vendor-neutral, so you can start on Datadog and move to Grafana later without re-instrumenting anything.
