Cayley is an open-source database for [Linked Data](https://www.w3.org/standards/semanticweb/data). It is inspired by the graph database behind Google's [Knowledge Graph](https://en.wikipedia.org/wiki/Knowledge_Graph) (formerly [Freebase](http://freebase.com)).

## [Documentation](https://cayley.gitbook.io/cayley/)
## Features
- Built-in query editor, visualizer and REPL
- Multiple query languages:
- [Gizmo](./docs/gizmoapi.md): query language inspired by [Gremlin](http://gremlindocs.com/)
- [GraphQL](./docs/graphql.md)-inspired query language
- [MQL](./docs/mql.md): simplified version for [Freebase](https://en.wikipedia.org/wiki/Freebase) fans
- Modular: easy to connect to your favorite programming languages and back-end stores
- Production ready: well tested and used by various companies for their production workloads
- Fast: optimized specifically for usage in applications
### Performance
Rough performance testing shows that, on 2014 consumer hardware and an average disk, 134m quads in LevelDB is no problem and a multi-hop intersection query -- films starring X and Y -- takes ~150ms.
