Dev Toolbox - Developer Utilities
CSS, JSON & Regex tools — all in one place, zero installs
A collection of essential developer tools — CSS Box Shadow Generator, JSON Formatter, Regex Tester, and Color Converter. All client-side, no data sent anywhere.
I built Dev Toolbox because I got tired of switching between
multiple sites just to format JSON, generate a box shadow,
or test a regex pattern.
So I combined the tools I use daily into one clean,
distraction-free page — no installs, no accounts, no data
leaving your browser. Everything runs 100% client-side.
What's inside:
🎨 CSS Box Shadow Generator — live preview + copy-ready code
📋 JSON Formatter & Validator — instant formatting with error detection
🔍 Regex Tester — real-time match highlighting + cheatsheet
🎡 Color Converter — HEX → RGB → HSL → OKLCH in one click
Would love to know: which tool do you reach for most as a dev?
And what should I build next? 👇
