Just Icon ⚡ - Create Stunning App Icons with AI in Minutes (Not Hours!)
As a developer, I've always struggled with one thing: creating beautiful app icons. You know the pain - you've built an amazing app, but when it comes to the icon, you're stuck with generic placeholder images or spending hours in design tools you barely understand.
That's exactly why I created Just Icon - an AI-powered CLI tool that generates professional app icons in minutes, not hours. And the best part? It's built with Go, so it's lightning fast and works everywhere! 🚀
🎯 The Problem Every Developer Faces
Let's be honest - we're developers, not designers. We can build complex algorithms, architect scalable systems, and debug the most obscure bugs, but ask us to create an icon and suddenly we're lost.
Traditional solutions are either:
- 🎨 Too complex - Design tools with steep learning curves
- 💸 Too expensive - Professional designers or premium tools
- ⏰ Too slow - Back-and-forth iterations taking days
💡 Enter Just Icon - Your AI Design Assistant

🎨 See the Magic in Action
Here's what blew my mind when I first tested it. Look at these results from simple prompts:
Glass-like Designs (Trending!)
Prompt: "glass-like color-wheel flower made of eight evenly spaced, semi-transparent petals"
Modern App Icons
Prompt: "neon-outlined calculator with electric blue glowing numbers"
Creative Concepts
Prompt: "glass-like sound wave pattern made of five curved, semi-transparent layers"
🎯 Pro Tips for Better Results
After generating hundreds of icons, here are my best practices:
1. Use Descriptive Adjectives
# ✅ Good
"minimalist calculator app with clean geometric numbers and soft gradients"
# ❌ Generic
"calculator icon"
2. Specify Style Elements
# ✅ Trending styles
"glass-like", "neon-outlined", "minimalist", "vibrant gradients"
# ✅ Color palettes
"soft pastel hues", "warm sunset colors", "electric blue"
3. Be Specific About Composition
# ✅ Detailed
"six triangular, semi-transparent blades forming a perfect hexagonal opening"
# ❌ Vague
"camera lens"
🔐 Privacy & Security First
As developers, we care about privacy. Just Icon is built with these principles:
- ✅ Zero tracking - No analytics, no telemetry
- ✅ Local storage - API keys stored in
~/just-icon.json - ✅ No accounts - Just download and use
- ✅ Open source - Inspect every line of code
