OpenTelemetry for instrumentation. ReplayStack for reproduction.
OTel gives you portable telemetry. ReplayStack gives you a developer workflow around one failed event—capture, inspect, replay, diff.
Keep your OTel pipeline
Export traces and metrics to your collector and backends—ReplayStack does not replace your instrumentation strategy.
Fill the reproduction gap
Traces show the path; ReplayStack stores the event payload and lets you replay it safely against non-prod endpoints.
SDK-friendly adoption
Thin Node, Python, and PHP SDKs plus HTTP ingest—add capture alongside existing OTel agents without a big migration.
