Every time I needed to format a JSON file, pick a color, or encode something in Base64, I ended up on some random website — cluttered with ads, forced sign-ups, or annoying popups. It got frustrating enough that I decided to just build my own toolkit.
That's how Devkitly was born — a free collection of 50+ developer tools, all in one place, built with Next.js.
What's inside
Some of the tools you'll find:
- 🧩 JSON Formatter & Validator
- 🎨 Color Picker
- 🔐 Base64 Encoder / Decoder
- 🔗 URL Encoder / Decoder
- 🕒 Timestamp Converter
- 🔑 UUID / Hash Generator
- ...and 40+ more, covering everyday dev tasks
Why I built it this way
- ⚡ Fast — no bloated ads or trackers slowing things down
- 🔓 No login required — open the tool, use it, done
- 🎯 Focused — each tool does one thing well
- 🆓 Completely free
