Teams look past Neo4j when the hourly per-gigabyte Aura billing is hard to forecast, when backup and clustering features of the self-managed server sit in Enterprise editions priced only through sales, or when they want another query language or hosting model. Most go to Memgraph, FalkorDB or TigerGraph, or to a cloud-native graph service.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. The first three alternatives
go to challengers, vendors outside the best-known brands in a category, wherever the category has them; the

What each alternative does differently
1. JanusGraph
Open-source distributed graph database on pluggable storage backends · United States
An Apache 2.0 project under the Linux Foundation, queried with Gremlin rather than Cypher. It stores data in Cassandra, HBase, Bigtable, BerkeleyDB or ScyllaDB and indexes with Elasticsearch, Solr or Lucene. You assemble and operate those parts yourself, so there is no vendor managed service.
Switch from Neo4j if you want a permissively licensed engine and your team can run the storage backend.
Pricing: Free under the Apache 2.0 license; you pay for the servers, storage backend and the engineers who run them. (open source)

2. NebulaGraph
Distributed open-source graph database with an enterprise and cloud edition · United States
An open-source edition sits beside an Enterprise edition and a managed cloud service. The cloud service offers a 14-day trial without a credit card. Its home page prints no price for Enterprise or Cloud, and the licence and query language were not stated there, so check both before committing.
Switch from Neo4j if you want to try a managed graph service for two weeks without entering a card.
Pricing: Open-source edition, an Enterprise edition by quote, and NebulaGraph Cloud pay as you go with a 14-day free trial and no credit card. (open source)

6. AllegroGraph
Distributed RDF graph and document database with a natural-language agent · United States
A triple store for semantic data: SPARQL 1.2, RDF-star, OWL 2 RL, SHACL and Prolog rules, described as fully ACID. It runs on premise, in Docker, or as AllegroGraph.cloud via the AWS and Azure marketplaces. No prices are printed, and a purchase page sends you to the vendor.
Switch from Neo4j if your model is RDF and you need SPARQL and reasoning rather than property graph queries.
Pricing: A free edition is offered; paid licenses are sold through a purchase process and cloud options, with prices not published. (free plan)

8. Stardog
Enterprise knowledge graph platform with virtual graphs and inference · United States
A knowledge graph platform with a no-cost, renewable one-year Free license that is not open source and is allowed for commercial use. Free leaves out high availability, caching, backups, LDAP and the full connector range. Enterprise, on premise or cloud, is quoted after a sales call.

11. Azure Cosmos DB for Apache Gremlin
Gremlin graph API on Microsoft's managed multi-model database · United States
Built on Apache TinkerPop and queried with Gremlin, with five tunable consistency levels. Microsoft's own introduction points analytical graph workloads and Gremlin migrations to Graph in Microsoft Fabric, and high-scale workloads to Cosmos DB for NoSQL. Read that guidance before choosing it for a new project.
Switch from Neo4j if you run on Azure, accept Gremlin and want to pick the consistency level per workload.
Pricing: Billed in request units with provisioned, autoscale or serverless options, plus storage; new accounts can enable a free tier of 1,000 RU/s and 25 GB. (free plan)

Questions and answers
Is there a free Neo4j alternative?
Yes, several. Memgraph Community Edition is free and open source, JanusGraph is Apache 2.0, and FalkorDB and TigerGraph publish free editions. Free tiers differ in limits, so compare high availability, backups and support before moving production data.
Which Neo4j alternative uses Cypher?
Memgraph uses Cypher, FalkorDB uses OpenCypher, and TigerGraph Community Edition supports Cypher and GQL next to GSQL. These keep the most existing Neo4j queries. JanusGraph and Cosmos DB use Gremlin, so they need rewrites.
Can I self-host instead of using Neo4j Aura?
Yes, Neo4j itself offers Community Edition under GPL3 for self-hosting, and Memgraph, JanusGraph and FalkorDB can also be run on your own servers. Self-hosting trades the hourly Aura bill for the work of operating and backing up the database.
How much does Neo4j cost at scale?
Aura Professional starts at 0.09 dollars per GB per hour and Business Critical at 0.20 dollars per GB per hour. Enterprise and Infinigraph carry no published price, so large deployments need a sales quote from Neo4j.
Which graph database fits RDF and SPARQL?
AllegroGraph, GraphDB and Stardog work with RDF and semantic data. AllegroGraph and GraphDB list SPARQL and reasoning support. Neo4j is a property graph database, so moving to an RDF store changes the data model, not only the vendor.
What happens to my Neo4j backups when I leave?
Neo4j Business Critical keeps daily backups for 30 days with hourly point-in-time restore. Download or export what you need before closing the instance, because the retention window belongs to the subscription. Confirm the export format against your target first.
