RouteReplay
RouteReplay is a desktop + web app for network engineers who need to understand why routing broke, not just that it broke. It ingests timestamped control-plane data (BGP updates, OSPF/IS-IS LSDB snapshots, device configs, and syslog) and reconstructs a timeline of route decisions: what changed, where it propagated, and which policy or attribute caused the final path selection. The MVP focuses on “incident replay”: you pick a time window and a prefix, and it generates a deterministic playback with diffs, key events, and a short narrative. This is not a full NMS replacement; it’s a focused forensic tool that complements existing telemetry stacks. Realistically, adoption will be easiest in teams already exporting BGP/LSDB data and willing to standardize collection. Without decent data hygiene, the app won’t magically fix visibility gaps.
