DevKnife

DevKnife is a collection of everyday utilities for developers, packed into one fast, native macOS app. Instead of jumping between websites, browser tabs, and small scripts, DevKnife keeps the tools you use most in one place - running locally on your Mac for speed, privacy, and focus. DevKnife covers many of the small but frequent tasks that come up during development — formatting and converting data, testing APIs, inspecting tokens, working with timestamps, generating test values, and handling common encoding or hashing tasks. Each tool is designed to be quick to access, easy to use, and focused on doing one thing well.
