| Aspect | Amazon Neptune | Neo4j (Aura / Enterprise) | Azure Cosmos DB (Gremlin API) |
|---|---|---|---|
| Starting Price | Usage-based; varies by deployment model, instance types, storage, I/O, backups | Published pricing pages vary by deployment (Aura tiers / self-managed) | Consumption/provisioned model with capacity metrics; published pricing available from the vendor |
| Best For | AWS-native managed graph workloads requiring Gremlin/openCypher/SPARQL and AWS integration | Teams prioritizing a graph-native platform with mature tooling and a Cypher-first experience | Azure-native applications needing multi-model distribution with a Gremlin API |
| Key Strength | Integration with AWS operational model; managed operations; Global Database option; multi-language support | Mature graph ecosystem and tooling; established Cypher lineage; graph data science platform | Global distribution and Azure ecosystem integration; multi-API support under Cosmos |
| Key Weakness | Pricing can be complex; openCypher compatibility differences vs Neo4j; some users perceive product composition | Can be expensive at scale; licensing and deployment complexity | Gremlin API compatibility nuances; not always optimized for graph-first workloads |
