What Hacker News says
2 sourcesShow HN: SparrowDB, SQLite of graph DB, written in Rust, Cypher compatible
SparrowDB is an embedded Cypher graph database written in Rust. It links into your process the way SQLite does.
I built it because I wanted a graph DB without running Docker or a cloud instance.
SparrowDB kicks butt at point lookups, global COUNT(*), and top-10 by degree but lags on traversals (1-hop, 2-hop, and variable-length paths).
It's an embedded engine with no parallel execution vs a warmed JVM server with a mature query planner.
The traversal workload is not the target. Agents, CLIs, serverless functions that need a knowledge graph without provisioning one, that's the target.
Cold start is ~27ms. If you're in a serverless context where Neo4j's startup time is disqualifying, that matters.
Bindings for Python, JavaScript/Typescript, and Ruby. All open the same on-disk format. Built-in MCP server for Claude Desktop. A Bolt protocol

server was just added, so gdotv and other Bolt clients can connect. At-rest encryption with XChaCha20-Poly1305. MIT.
