Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 9, Utility: 6)

OpsGraph is a self-hosted investigation workspace that lets you ask natural language questions of PostgreSQL data while capturing the exact queries, rows, and limits behind each answer as inspectable evidence. It combines LangGraph-orchestrated agents, AST-validated read-only SQL, and a citation-first UI, positioning itself against opaque AI database assistants by making every claim auditable.

Target audience: backend devs, data engineers, sre/ops engineers
