Safe production event replay for developers

ReplayStack is built for the moment between “we know it failed” and “we proved the fix”—replay in safe mode, compare responses, ship with evidence.

Replay modes that respect prod

Target staging endpoints, strip secrets automatically, and avoid re-firing side effects on live systems.

Diff what changed

See how a code or config change alters the replay outcome—fewer “works on my machine” regressions.

Shareable bug reports

Export timelines and replay results so PMs and support do not need shell access to understand the failure.

Compare how ReplayStack fits your stack: Datadog, OpenTelemetry, Sentry.
