Hey everyone! 👋 I built URL Decode Online because I was tired of dealing with cluttered, ad-filled URL decoder tools while debugging API requests. I needed something clean, fast, and privacy-focused that just works. What started as a simple weekend project evolved into a full-featured tool with: - 12-language support for global developers - Multi-layer auto-detection - 100% client-side processing (your data never leaves your browser) - Built with Next.js 16 for optimal performance I'm a developer myself, so I know how frustrating it is to deal with encoded URLs, especially when working with REST APIs or analyzing tracking parameters. This tool is what I wish existed when I started coding. Would love to hear your feedback! What features would make this even more useful for your workflow?

I'm currently thinking about adding a 'Batch Processing' feature or a 'CURL command generator'. Which one would you find more helpful for your daily debugging?
