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

0sql is a deterministic SQL planner that resolves business-term query specs against a governed semantic model, outputting correct SQL without ever executing it. It stands out for its explicit refusal mechanism, 13-dialect support, row-level security integration, and MCP agent interface, making it a secure, LLM-friendly alternative to Cube and MetricFlow.

Target audience: backend devs, data engineers, analytics engineers, AI agent developers
