history
Project history and usage
Cayley is an open-source linked-data graph database and CLI that presents graph storage, query, REPL, HTTP server, and visualization workflows in a Go package.
Project history
The project describes itself as inspired by the graph database behind Google's Knowledge Graph, formerly Freebase. Its public GitHub repository was created in 2014 and the README frames Cayley around linked data, multiple query languages, and application-oriented graph workloads.
Adoption history
Cayley's README says it is production-ready and used by various companies for production workloads. In package-manager terms it has also been carried by Homebrew and Nix, giving Unix users a one-command install path for a standalone graph database.
How it is used
Users typically run `cayley http` for the web interface/API, load RDF-like quad data, and query it with Gizmo, an MQL-style language for Freebase users, or GraphQL-inspired queries. The official configuration docs describe YAML/JSON config files plus command-line and environment-variable overrides.
Why package nerds care
Cayley is interesting as a self-contained Go graph database package: one formula installs a graph server, REPL, query tooling, and multiple storage backends without deploying a larger database stack. Its Freebase/Knowledge Graph lineage gives it a distinct niche among RDF and linked-data tools.
