A native macOS Postgres GUI that can draft SQL from natural-language questions, using either a configured cloud model or Apple’s on-device Foundation Model on supported Macs.

Open-source semantic layer for warehouses that infers table, column, join, and business-rule metadata, then serves it to AI agents through MCP and CLI checks.

Open-source text-to-SQL engine tuned to your own database, with configurable pipeline stages, policy checks, and an evaluation harness for measuring performance on real schemas.

Claix is a hosted controlled database retrieval layer for AI agents. It lets agents query Postgres or Supabase through read-only, route-based access without writing SQL, and exposes endpoints over REST, MCP, and A2A.
