Relate launches an open-source embedded graph database for AI agents

Relate is an open-source embedded graph database for AI agents that runs inside the application with no server to deploy and no signup, storing data in memory, a directory or a single .rl file. It speaks openCypher and is tested against the openCypher TCK, and ships with an agent skill plus an MCP endpoint so agents such as Claude Code, Codex and Cursor can write Cypher queries against connected facts. Installation runs through a curl script that verifies release signatures and SHA256 checksums, and libraries are offered for Rust, Python, JavaScript, WebAssembly, Go, Java, Swift and C.
