Postquel
Postquel is a free, MIT-licensed PostgreSQL client built natively for macOS 15+ with SwiftUI and AppKit. It includes table browsing and editing, a SQL editor, foreign-key navigation, schema inspection and SSH tunnels. Database passwords stay in macOS Keychain. The optional assistant works through Claude Code, Codex or Cursor Agent already installed and signed in on the Mac. It can inspect schemas and run read-only queries, then propose changes for the user to review, dry-run and apply. Third-party AI services may have their own charges. Postquel is an early prototype and a work in progress, available for Apple silicon and Intel. Source: https://github.com/frizurd/postquel
