GraphSentry

GraphSentry is a web app (with optional desktop agent) that monitors knowledge graphs in production and flags when they become untrustworthy. It continuously checks schema changes, entity duplication, broken links, unexpected cardinality shifts, and source freshness across pipelines feeding Neo4j/RDF stores. It also runs lightweight anomaly detection on graph metrics (degree distributions, community structure shifts, orphan rates) and ties each alert to the upstream source and transformation step that likely caused it. The product outputs actionable tickets: what changed, why it matters, blast radius (which downstream apps/LLM-RAG answers are impacted), and the fastest rollback or patch. This is an AI app + traditional app combination: AI helps classify anomalies, dedupe entities, and summarize root-cause narratives, but the core value is reliable monitoring, governance, and auditability. It’s built for teams who already have a graph and are tired of silent failures.
