About CodingTool.dev
Fast, free, and powerful developer tools for programmers worldwide
CodingTool.dev was built to help developers save time and work more efficiently. We believe that essential developer utilities should be fast, free, and accessible to everyone, regardless of their location or budget.
Inspired by tools like DevUtils and coding.tools, we bring together multiple utilities like JSON Formatter, Regex Tester, JWT Decoder, Base64 Encoder, and many more into one convenient, privacy-focused platform.
All tools run directly in your browser. Your data never leaves your device. We do not store, transmit, or process any of your sensitive information on our servers.
Client-side processing means instant results with no server delays. No loading spinners, no waiting for uploads—just immediate, responsive tools.
Available in 6 languages (English, Indonesian, Chinese, Japanese, Russian, and more). No account required, no login needed—just open and use.
Built by developers, for developers. Clean interface, keyboard shortcuts, dark mode support, and features designed for real-world development workflows.
