Debug Replay

Record and replay production requests locally.

Implementation Details

"It works on my machine" is a phrase we're trying to eliminate. Debug Replay brings production reality to your local terminal.

Traffic Shadowing

The tool hooks into your production load balancer or middleware to "shadow" a percentage of traffic, stripping away PII (Personally Identifiable Information) before storing the request payload.

Local Playback

Developers can then fetch these specific requestIDs and replay them against their local service, receiving the exact same input that caused a production error or performance bottleneck.
