    Command-K palette

    Find any tool and open Settings from a global, keyboard-first palette.

  4. 04

    Files and drag-and-drop

    Menu-bar quick tools

    Optionally pin frequent utilities for access without navigating the main window.

Local by default

Your working data stays yours.

Thirty-three tools operate entirely on your Mac. There are no accounts, analytics, ads, tracking, third-party SDKs, or developer-operated traffic relays. Developer-tool processing is local by default. Apple processes App Store payments; the app verifies access through StoreKit at runtime, Hexa DevKit never receives payment credentials, and entitlement and offer metadata remain runtime-only and are not persisted.

  • The developer does not receive network-tool traffic.
  • Optional API history stays local, excludes bodies, and removes sensitive headers and query values.
  • User-selected files are processed locally unless you explicitly send content through API Client.
  • Website hosting may produce infrastructure logs controlled by Cloudflare; the website adds no analytics or cookies.

Only three tools access the network

Each connects only after an explicit action and communicates directly with the destination you choose.

01

API Client

Sends the REST or GraphQL request you prepare.

02

DNS Lookup

Resolves the record type and host you enter through the Mac system resolver.

03

WebSocket Client

Connects to the secure wss:// endpoint you specify.
