As answered by people managing Codility and DevKnife.
DevKnife's answer:
DevKnife is a lightweight, native macOS app that bundles everyday developer utilities into one place. Instead of switching between separate websites, CLI tools, or multiple apps, you can handle tasks like JSON formatting, WHOIS lookups, port scanning, JWT decoding, hashing, and more from a single, fast, offline-friendly tool.
Its uniqueness comes from combining these small but essential tools into a consistent, Mac-native experience.
