As answered by people managing JSONLint and DevSexy.
DevSexy's answer:
DevSexy combines 35 native macOS developer tools with a workflow built around global Option shortcuts. Use Option-J for the JSON formatter, Option-B for Base64, and Option-T for Unix time; hold Option to see the shortcut HUD, then use Silent Mode when the keys feel familiar. Quick menu-bar popups handle small tasks, while the full workbench supports longer sessions. Tool input is processed locally and the Mac app works offline. The website also offers 35 free online developer tools with browser-local processing.
DevSexy's answer:
Developers who frequently inspect API payloads, debug JWT tokens, format JSON, convert Base64, test regular expressions, compare configuration changes, or convert Unix timestamps. The native macOS app fits developers who want offline developer utilities close to their coding workspace. The free browser tools are useful when a developer wants to complete a specific task with local processing and no account or upload step.
DevSexy's answer:
The native macOS app is built with Swift, SwiftUI, and AppKit. The free online developer tools use Nuxt, Vue, and TypeScript, with tool input processed locally in the browser.
