OrderGuard

OrderGuard is a web app + CLI that continuously tests and monitors event ordering across your real-time pipeline (Kafka/Kinesis/PubSub, WebSockets, microservices). It replays sampled production traffic into a sandbox, injects realistic disorder (out-of-order delivery, duplicates, clock skew, retries, partial failures), then verifies invariants you define (e.g., “payment must follow authorization,” “inventory can’t go negative,” “state transitions are monotonic”). It flags ordering-sensitive consumers, pinpoints the exact event sequence that breaks state, and generates minimal repro traces you can run locally or in CI. This is not a generic observability dashboard; it’s a focused “ordering correctness” tool that turns intermittent, expensive incidents into deterministic test cases. Expect some setup friction: you’ll need to define invariants and integrate with your event bus. If you won’t invest in that, this won’t help you.
