SeqSentry

SeqSentry is a web app (with optional lightweight desktop agent) for engineering teams who run distributed systems and keep arguing about “what happened first.” It ingests event streams from Kafka, Kinesis, Pub/Sub, HTTP logs, and OpenTelemetry, then reconstructs probable ordering using hybrid logical clocks, vector-clock hints, and per-service monotonic counters. The product highlights where ordering is unknowable (clock skew, missing IDs), quantifies confidence, and pinpoints the exact hop that introduced reordering or excessive buffering. It generates reproducible “ordering proofs” you can attach to incident tickets: timelines, causal graphs, and a minimal set of correlated events. It’s not a magic fix—if your instrumentation is bad, it will say so and show what to add. The MVP focuses on one-click integrations, a single timeline view, and actionable “instrumentation gaps” recommendations.
