The Ultimate Developer Utility Belt

Dev Mini Tools is built as a fast, modern single-page application that provides instant access to essential daily development tasks—all without ever leaving your browser.

We grew tired of constantly searching for scattered web tools filled with ads just to decode a token or format some JSON. So, we engineered our own clean, unified ecosystem.

Core Arsenal

The platform is strictly organized by categories to keep your workflow frictionless:

• Frontend & Design: Generate color shades, check WCAG accessibility contrast ratios with live previews, and simulate how your site appears on Google and social media via Open Graph tags.
• Data Handling: Instantly format, minify, and validate JSON data securely in the browser.
• Auth & Security: Quickly decode JWT tokens to inspect headers, payloads, and claims, including expiry and algorithms.
• References: A complete, searchable reference for all HTTP response status codes and RFC sources.

Engineering Stack

Built with uncompromising performance using React 19 (via Vite), TypeScript, and Tailwind CSS. It relies on a highly modular architecture that makes contributing and adding new tools incredibly straightforward.

This project is fully open-source and actively maintained.
