DriftReplay

DriftReplay is a web app + CLI that captures real API traffic (sanitized), then replays it deterministically against staging or local environments to reproduce flaky bugs and contract drift. Instead of hand-writing mocks that inevitably diverge, teams record real request/response pairs, auto-redact secrets/PII, and generate a replay suite that can run in CI. It highlights diffs in status codes, headers, and JSON paths, and can “pin” known-good behavior as a baseline. It also supports partial replays (only specific endpoints), rate-limited playback, and environment variable mapping so the same capture can run across dev/stage. This is not magic: it won’t fix broken architecture or missing observability, but it will make “can’t reproduce” incidents rarer and shorten the loop from bug report to failing test.
