What is FalkorDB used for?

FalkorDB is a low-latency graph database built on sparse matrices and linear algebra, aimed at knowledge graphs and GraphRAG for LLM applications. It is a good fit for knowledge graphs for LLM retrieval, agent memory stores and fraud detection graphs.

Is FalkorDB open source?

Yes. FalkorDB is open source under a custom licence. Its source code is on GitHub at FalkorDB/FalkorDB and is written mainly in Rust.

Yes. FalkorDB is open source, so the software itself is free to use under the terms of its own licence. A managed cloud version is also available, with paid plans from $350 per month.

Can I self-host FalkorDB?

Yes. FalkorDB can be self-hosted on your own server or infrastructure.

What is FalkorDB an alternative to?

FalkorDB is an open-source alternative to Amazon Neptune, Neo4j AuraDB and TigerGraph. Other open-source alternatives to Amazon Neptune include Neo4j, NebulaGraph and Dgraph.

Is FalkorDB actively maintained?

Yes. The most recent commit to FalkorDB was on 1 October 2026, and the latest release is v6.0.1, published on 1 October 2026. The project has 6.6k stars on GitHub.

About FalkorDB

FalkorDB is a graph database built for low-latency queries, with a particular focus on supplying knowledge graphs to large language models in GraphRAG setups. It stores data as property graphs and represents connections with sparse adjacency matrices, which the authors say keeps storage compact and traversal fast.

Instead of walking edges one at a time, queries are executed through linear algebra operations built on GraphBLAS. The project lists generative AI applications, agent memory, fraud detection and cloud security as target uses, and it is multi-tenant, so many separate graphs can share one deployment. Graphs are queried with Cypher-style statements, and repository topics also point to developer tooling and real-time use.

The code is published on GitHub under a license that GitHub classifies as 'Other', so check the repository's license terms before commercial use. You can run FalkorDB yourself, commonly as a container, or use the vendor's hosted cloud database service.
