Galactus DB is a modern property-graph database for the real world — scalable, fast and built for what's next. Parameterised Cypher over Bolt 4.4, native drivers for seven languages, and vector, spatial and full-text indexes with graph analytics built in. It ships as a statically linked Rust binary in a scratch container.
It's also what's running underneath this city: every conversation with the agents in the plaza, their knowledge base (searched with Galactus DB's BM25 full-text index) and every enquiry lives in Galactus DB, reached through its native Rust driver.

Cypher, with APOC built in
Parameterised Cypher with selected APOC functions and procedures. Bolt 4.4 means existing Neo4j-compatible tooling connects.
Every index you need
Vector, spatial, full-text, hash, range, composite and element indexes — similarity search sits next to the graph, not in another system.
Graph analytics
Communities, ranking and shortest paths on a graph projection, with resource limits per job.
Tiny footprint
Graph structure and indexes in memory, base properties on disk with a bounded cache. Linux AMD64 and ARM64 via Docker.
Explorer workbench
A browser workbench to get to know your graph: graph, spatial, table and JSON views.
Native drivers
C#, Rust, Java, Go, Node, C++ and Python — early access, source available on GitHub.
Questions
What is Galactus DB?
A self-hosted property-graph database written in Rust. It speaks parameterised Cypher over Bolt 4.4 and includes vector, spatial and full-text indexes plus graph analytics, in a container of about 6 MB.
Does it work with Neo4j tools?
It speaks Bolt 4.4 with parameterised Cypher and selected APOC functions and procedures, so existing Neo4j-compatible tooling can connect.
Where does it run?
On Linux AMD64 and ARM64 via Docker, with native drivers for C#, Rust, Java, Go, Node, C++ and Python.
Figures from galactusdb.com. Benchmarks against Neo4j 5.26.30 Community: 100,000 people and 200,000 relationships on 8 CPU / 8 GB containers, medians of three passes. The 1.9× bulk-load figure is for the default buffered durability mode (1.5× in durable group mode). Neo4j was about 2.5× faster on filtered label scans.
