I Built a Free Developer Toolkit Because I Was Tired of Opening 10 Different Websites
As developers, we've all done this.
Need to format some JSON? Open one website.
Need to decode a JWT? Open another.
Need to convert Base64? Another tab.
Need to generate TypeScript interfaces from JSON? Yet another website.
After doing this almost every day, I finally thought, "Why isn't there one place with all the tools I actually use?"
So I spent the last few weeks building DevToolkit.
The idea wasn't to create another huge collection of random utilities. I wanted a clean, fast, modern toolkit that developers could actually enjoy using.
What it includes today
JSON Formatter & Validator
JWT Decoder
Base64 Encoder & Decoder
JSON to Code Generator (TypeScript, Dart, Java, Go, Rust, Python, and more)
Unix Timestamp Converter
Everything runs directly in your browser whenever possible, so your data stays on your machine.
Built with
React
TypeScript
Vite
Tailwind CSS
Monaco Editor
Framer Motion
Vercel
What I'm working on next
This is only the first version. Over the next few weeks I'm planning to add:
Regex Tester
UUID Generator
SQL Formatter
YAML β JSON Converter
XML Formatter
QR Code Generator
Image Tools
More Time Tools
AI-powered developer utilities
My goal is simple: build one toolkit that developers can bookmark and use every day.
If you're interested, I'd genuinely appreciate your feedback. Whether it's a bug, a feature request, or a tool you'd like to see added, let me know in the comments.
