Postquel

Postquel is a native PostgreSQL client for macOS that integrates with existing local AI agents to query and manage database tables.

Postquel is a native PostgreSQL client built with SwiftUI and AppKit for macOS. It allows users to browse and edit database rows, manage table structures, and write SQL queries. The application includes an AI assistant that integrates with locally installed tools like Claude Code, Codex, or Cursor Agent. Users can ask questions about their data or describe queries in plain language. The assistant reads the schema to generate SQL and only proposes changes for the user to review. No third-party API keys are stored within the application, as it utilizes the user's existing authenticated sessions on their machine.
