GraphSentry
GraphSentry is a web app (with optional CLI) that continuously tests and monitors graph database behavior as your data and queries evolve. Teams using Neo4j, Amazon Neptune, or JanusGraph often get burned by silent performance regressions, cardinality explosions, or schema/constraint drift after data loads and query changes. GraphSentry runs scheduled “query canaries” (representative Cypher/Gremlin/SPARQL queries), tracks latency, result-shape metrics (node/edge counts, paths returned), and detects anomalies using lightweight statistical baselines. It also validates constraints/indexes, flags risky query plan changes, and produces a clear regression report tied to a Git commit or deployment. This is not a generic APM; it’s graph-specific QA for production reliability. Realistically, the product wins only if it integrates cleanly into CI/CD and provides actionable, low-noise alerts that engineers trust.
