I Built a Free Tool Site with 15+ Developer Tools — No Sign-up, No Ads, No Bullshit

Hey everyone! 👋

I'm a developer who got tired of visiting 10 different websites to do simple
tasks like formatting JSON, compressing images, or generating QR codes. So I
built DevToolBox — a single place with 15+ free online tools, all running in
your browser with no sign-up required.

Why I Built This

Every time I needed a quick tool, I'd end up on a site full of ads, popups, or
"create an account to continue" walls. I wanted something clean, fast, and
respectful of users' time and privacy.

The idea was simple: one website, all the tools you need, zero friction.

What's Inside

Here are some of the tools available:

Developer Tools:

JSON Formatter & Validator — Format, validate, minify JSON with syntax highlighting
Base64 Encoder/Decoder — Encode and decode Base64 strings instantly
UUID Generator — Generate v4 UUIDs in bulk
🔧 Unix Timestamp Converter — Convert between timestamps and human-readable dates
🔧 Regex Tester — Test regular expressions with real-time matching
🔧 Markdown Preview — Write Markdown and see the output live
Hash Generator — MD5, SHA-1, SHA-256, SHA-512
🔧 Diff Checker — Compare two texts side by side

Daily Tools:

🖼️ Image Compressor — Compress images right in your browser
Image Format Converter — Convert between PNG, JPG, WebP
Password Generator — Create strong, customizable passwords
📱 QR Code Generator — Generate QR codes with custom colors
BMI Calculator — Calculate Body Mass Index
🎂 Age Calculator — Calculate exact age from birth date
📝 Word Counter — Count words, characters, sentences
📏 Unit Converter — Length, weight, temperature, and more

How It's Built

The whole site is a Vue 3 + TypeScript + Vite project with Tailwind CSS for
styling. Everything runs client-side — no data is ever sent to a server, which
means your data stays on your device.
