Installation

Requirements

• A Mac running macOS 26 or later
• That's it. No account, no license key, no internet connection needed after download.

Install

1. Open Developers Kit on the Mac App Store — or open the App Store on your Mac and search for Developers Kit.
2. Click Get (or the price button), then confirm with Touch ID or your Apple Account password.
3. Launch Developers Kit from Launchpad or Spotlight (⌘Space, type "Developers Kit").

First launch — the 60-second tour

When the app opens you'll see one window with a sidebar on the left. The sidebar has two groups:

• Apps — Password Manager, Database Client, ENV Manager, Clipboard. These hold data and have their own storage.
• Utilities — JWT Inspector, JSON Formatter, Diff Tool, Port Manager. These are paste-in → get-answer tools.

Click any tool to switch to it. Your work is kept when you switch away and back — tools stay alive in the background of the window.

The menu bar icon

Developers Kit also puts an icon in your menu bar (top-right of your screen). From there you can:

• Jump straight to any tool.
• Open the Clipboard quick panel — your recent and pinned clips, one click to copy.

Next step

Read Permissions & Privacy — it explains the Touch ID prompts you'll see, and why they're a feature, not an annoyance.
