One app. Every developer tool you ever needed!
JSON converters, encoders, cryptography, formatters, code generators and more.
All offline. All instant. All in one place.
The Toolbox
From parsing to cryptography; if you do it regularly, it's already here.
Why Developers Love It
Hit ⌘P and type to reach any of the 100+ tools in milliseconds. No mouse, no menus. Your hands stay on the keyboard where they belong.
Navigate and operate entirely with your keyboard. Every tool is accessible without touching the mouse, keeping your workflow fast and efficient.
Work on multiple tasks simultaneously. Open JSON in one tab, run a regex test in another, generate UUIDs in a third.
Syntax highlighting, Code Folding, and an interface your fingers already know. Every input field is a proper editor, not a plain textarea.
Developer Tools Pro is 100% offline. No account needed. No telemetry. No network calls. Your code, your secrets, your data, process everything locally and keep it that way.
