Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 7)

SLayer is a semantic layer that enables AI agents to query databases using a structured DSL of measures, dimensions, and filters, while automatically managing data models. Its innovative combination of an AI-adaptive semantic layer with multi-interface support (MCP, REST, CLI, Python) and query-time aggregation makes it a standout tool for agentic data analysis. It fills a known gap in bridging natural-language AI agents with structured database queries.

Target audience: backend devs, data engineers, ai engineers
