I Built 30+ Developer Tools in One App (Because I Was Tired of Opening 47 Browser Tabs) 🤦‍♂️

#webdev #showdev #tooling #productivity

The 2 AM Problem Every Developer Faces

Picture this: It's 2 AM. You're debugging an API response. Your browser has 47 tabs open:

  • Tab 1-3: "best JSON formatter online"
  • Tab 4-7: Various CSS minifiers (half don't work)
  • Tab 8-10: Base64 encoders (one has sketchy ads)
  • Tab 11-15: You forgot what these were for
  • Tab 16-47: Stack Overflow answers you opened 3 hours ago

Sound familiar? Yeah, me too. 😅

The "Aha!" Moment

After the 47th time searching for "free JSON formatter no login", I had an epiphany:

What if there was ONE tool that did EVERYTHING? And actually respected my privacy?

So I built it. Meet Code Formatter - your Swiss Army knife for web development.

What's Inside? (The Good Stuff) 🛠️

1. Code Formatters & Beautifiers

  • JSON Formatter (with syntax highlighting)
  • HTML Beautifier
  • CSS Formatter
  • JavaScript Formatter
  • SQL Formatter
  • XML Formatter

No more copy-pasting into sketchy websites. Format your code instantly.

2. Minifiers

Because production code shouldn't look like a novel:

  • CSS Minifier
  • JavaScript Minifier
  • HTML Minifier

One click. Instant compression. Ship faster.

3. Data Converters

The boring stuff made easy:

  • JSON to CSV
  • CSV to JSON
  • Excel to HTML Table
  • JSON to XML
  • XML to JSON

Ever needed to convert client data at 11:59 PM? Now you can.

4. Security Tools

For when you need crypto (the good kind):

  • Hash Generator (MD5, SHA-1, SHA-256, SHA-512)
  • JWT Decoder
  • Base64 Encoder/Decoder
  • URL Encoder/Decoder

Perfect for testing auth flows without sending data to random websites.

5. CSS Generators

Stop googling "glassmorphism generator":

  • Glassmorphism Generator
  • Box Shadow Generator
  • Text Shadow Generator
  • Gradient Generator
  • Aspect Ratio Calculator

Copy the CSS. Done. Ship it.

6. Utility Tools

The stuff you need but never bookmark:

  • Text Diff Checker
  • Lorem Ipsum Generator
  • Mock Data Generator
  • Color Picker
  • Unit Converter

7. Preview Tools

  • HTML Live Preview
  • Markdown Preview
  • Social Media Preview (Twitter, Facebook, LinkedIn cards)

Test your meta tags before shipping. Your designer will thank you.

But Wait... Is My Data Safe? 🔒

Here's the best part: I literally cannot see your data. Even if I wanted to.

🛡️ 100% Client-Side Processing

Every single operation happens in your browser. Not my server. Not the cloud. YOUR machine.

// This is what happens when you format JSON:
1. You paste code
2. JavaScript processes it locally
3. Result appears
4. Zero network requests

// What DOESN'T happen:
❌ No server upload
❌ No database storage  
❌ No tracking scripts
❌ No analytics on your code
Enter fullscreen mode Exit fullscreen mode

Why This Matters

When you use most online tools, your code goes through their servers. That means:

  • They can log it
  • They can store it
  • They can analyze it
  • They might have a data breach

With Code Formatter:

  • Your API keys stay yours
  • Your production code stays private
  • Your client data stays confidential
  • Your secrets stay secret

I built this because I was tired of sketchy tools asking for "permissions" to process my code.

The Tech Stack (For the Curious) 🤓

  • Frontend: React + Vite (blazing fast)
  • Styling: Tailwind CSS (because life's too short for vanilla CSS)
  • Processing: 100% client-side JavaScript
  • Hosting: Vercel (for that sweet Edge network)
  • Libraries:
    • Prettier (code formatting)
    • Papaparse (CSV parsing)
    • Crypto-JS (hashing)
    • Monaco Editor (syntax highlighting)

No backend. No database. No BS.

Features That Make Me Proud 😊

1. Works Offline

After the first load, it's yours forever. No internet? No problem.

2. No Login Walls

I hate those "Sign up to continue" popups. You won't find them here.

3. No Ads

Your time is valuable. No distractions.

4. Mobile Optimized

Need to format JSON on your phone at 2 AM? (We've all been there) It works.

5. Keyboard Shortcuts

Because developers love keyboard shortcuts:

  • Ctrl/Cmd + B - Format/Beautify
  • Ctrl/Cmd + M - Minify
  • Ctrl/Cmd + K - Clear

6. Dark Mode

Light mode? In 2025? Come on. 😎

7. Open Source

Check the code yourself: [GitHub Link]

Don't trust me? Read the code. That's the beauty of open source.

Real Use Cases (From Real Devs)

Case 1: The API Response Formatter 

// You get this mess from an API:
{"user":{"name":"John","data":{"posts":[{"id":1,"title":"Hello"}]}}}

// One click later:
{
  "user": {
    "name": "John",
    "data": {
      "posts": [
        {
          "id": 1,
          "title": "Hello"
        }
      ]
    }
  }
}
Enter fullscreen mode Exit fullscreen mode

Case 2: The Last-Minute Minifier

It's 11:58 PM. Deploy deadline is midnight. Your CSS is 150KB.

One click → 47KB. Shipped with 2 minutes to spare. 💪

Case 3: The Client Data Converter

Client sends you an Excel file. You need it as an HTML table.

Upload → Convert → Copy → Done. (No Excel license needed)

Case 4: The JWT Debugger

Auth isn't working. Is the JWT valid?

Paste → Decode → Oh, it expired 3 hours ago. Mystery solved.

Performance Numbers 📊

Because developers love benchmarks:

Operation Time File Size
Format 1MB JSON ~50ms Client-side
Minify 500KB CSS ~30ms Client-side
Convert 1000 rows CSV ~100ms Client-side
Generate SHA-256 hash ~10ms Client-side

All tested on a 2020 MacBook Pro. Your mileage may vary.
