Grafio

Grafio (v7.15.1) is a high-performance, in-memory graph database for Node.js with native Cypher query support and pluggable storage backends (in-memory built-in, MongoDB via separate package). It supports BFS/DFS traversal, atomic transactions with automatic rollback, DAG validation, topological sort, and Mermaid graph export. Key differentiators: Cypher-native query engine compatible with OpenCypher, smart LRU/LFU/FIFO caching with budget enforcement, and TypeScript-first design. Release cadence: irregular, with active development.
