Use Datadog for signals. ReplayStack for the exact failed event.

Teams on Datadog still rebuild failing requests by hand. ReplayStack sits next to Datadog—capture, timeline, safe replay—without ripping out your observability stack.

What Datadog excels at

Fleet metrics, APM traces, log analytics, and on-call dashboards across services and infrastructure.

What ReplayStack adds

Per-event timelines, payload-aware capture, and safe replay when you need to reproduce one backend failure—not another dashboard panel.

Typical workflow

Spot the anomaly in Datadog → open the matching ReplayStack event → replay with masking → verify the fix → attach evidence to the ticket.
