The Take

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).

Target Audience

Web developers, frontend engineers, designers, QA engineers

Post Description

I built 9 free browser-based developer tools, all hosted on GitHub Pages with zero cost. Includes JSON Formatter, Regex Tester, CSS Grid Generator, Color Palette Generator, Markdown Preview, Clipboard Manager, Password Generator, Unit Converter, and API Response Viewer. Everything runs client-side, no sign-ups, no tracking. Built as a weekend project to scratch my own itch.

Free, private developer tools in the browser

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.
