Protocols Bolt, HTTP/REST, GraphQL (HTTP), gRPC

gRPC surface is Qdrant-compatible (Points.Search/Query) plus an additive NornicSearch gRPC service.

  • It speaks Neo4j's language through Bolt and Cypher, exposes REST, GraphQL, and gRPC interfaces, and can preserve Qdrant-style client workflows where that helps migration.

Released 2025-12

Confirms current value. The repo's own pre-1.1 changelog gives v1.0.0 as 'First standalone release (December 6, 2024)', which is an internal typo — the very next line in the same file dates v1.0.6 to 2025-12-12, consistent with a December 2025 first release.

Language Go

Confirms current value. Build-from-source instructions use `go build`, and Go is by far the dominant language in the repository's source tree.
