helix-db alternatives
Curated alternatives to helix-db — and why you'd switch.
hydradb
Object-store-native distributed graph DB in Rust: graph on SlateDB over S3, snapshot-consistent OpenCypher, GraphBLAS traversal, Neo4j Bolt 5.x compatibility, disaggregated data nodes and indexers.
Why switchBoth are Rust graph databases built on object storage. hydradb speaks OpenCypher and Neo4j Bolt for drop-in compatibility; HelixDB fuses vector and BM25 search into the graph engine for agent retrieval.
Full comparison →latticedb
Embedded single-file graph database in Zig: graph traversal, HNSW vector search and BM25 full-text in one query language, plus a durable event log — built for Graph RAG and local agent memory.
Why switchSame bet: traversal, vector ANN and BM25 in one engine for Graph RAG and agent memory. latticedb is an embedded single-file Zig library; HelixDB runs as a server or embedded on object storage with four SDKs.
Full comparison →omnigraph
Lakehouse graph database for agent context — graph, vector and full-text retrieval fused in one runtime on branchable Lance/S3 storage; agent fleets write on isolated branches and merge Git-style.
Why switchBoth fuse graph, vector and full-text retrieval over object storage for agent context; omnigraph adds Git-style branch-and-merge on Lance, HelixDB focuses on transactional OLTP writes.
