## Memgraph Key Advantages
- 7,500+ GitHub stars under BSL/Apache-2.0 built in pure C++ with in-memory execution delivering sub-millisecond Cypher query response times
- Native Kafka, Redpanda, and Pulsar streaming graph integrations with dynamic PageRank and community detection algorithms
- Drop-in Bolt and openCypher compatibility cutting commercial Neo4j Aura managed cloud charges by 94.6% ($185/mo VPS vs $3,450/mo Aura)

## NebulaGraph Key Advantages
- 10,800+ GitHub stars under Apache-2.0 engineered as a distributed, shared-nothing architecture scaling to tens of billions of vertices and edges
- Separates compute and storage engines enabling independent horizontal elasticity on Kubernetes clusters
- Enterprise-grade multi-tenant access control and sub-10ms distributed traversal replacing $4,200/mo Amazon Neptune clusters (-94.2%)
