Dev Tools Hub – 10 free browser-based developer utilities
Yet another dev tools collection when CyberChef and browser DevTools already exist.

Nice, no-friction collection — everything runs in the browser with zero signup and a clear grid of tools like JSON formatter, regex tester, JWT decoder and timestamp converter. Useful for quick one-off tasks and privacy-minded users, but there’s nothing here that CyberChef, DevTools extensions, or dozens of other static tool bundles don’t already do better (no chaining, no advanced features, just standalone widgets).
Web developers, frontend engineers, designers, QA engineers
Yet another dev tools collection when CyberChef and browser DevTools already exist.
Every tool here exists in browser DevTools or CyberChef with more features.
Everything important runs in the browser: JSON formatters, a JWT debugger explicitly marked 100% client-side, and a new Database Design Studio that turns SQL/Prisma schemas into draggable ER diagrams you can export as PNG. The product’s hook is convenience plus privacy — a single place to grab many small tools without sending snippets to a server. It’s useful and nicely designed, but the core idea is a well-curated bundle rather than a novel technical breakthrough.
Every tool exists on CyberChef and in browser DevTools already.
Yet another dev tools collection, but the steganography tool actually runs client-side.
