ReplayGate

ReplayGate is a middleware tool that captures real production HTTP/gRPC traffic (with strict redaction) and replays it into staging, canary, or local dev to reproduce bugs and validate changes. Teams waste days chasing “can’t reproduce” issues because test data and mocks don’t reflect reality; this product makes failures repeatable. It sits as a lightweight proxy/sidecar, stores request/response traces with deterministic ordering controls, and replays them with configurable rate, jitter, and dependency stubbing. Built-in PII/secret scrubbing and allow/deny rules prevent accidental data leaks. It also compares replay results to baselines (status codes, payload diffs, latency) to flag regressions before release. This is a web app (control plane) plus a deployable agent (container) for Kubernetes and VM environments. It’s a combination traditional + AI app: AI helps generate redaction rules and summarize diffs, but core value works without it.
