```

### Cron Expression

```
Input: */15 9-17 * * 1-5
Output: "Every 15 minutes, between 09:00 and 17:59, Monday through Friday"

# Input:
docker run -d --name myapp -p 8080:80 -v data:/app/data -e DB_HOST=localhost nginx:alpine

# Output:
services:
  myapp:
    image: nginx:alpine
    ports:
      - "8080:80"
    volumes:
      - data:/app/data
    environment:
      DB_HOST: localhost
```

## FAQ

**Q: How is IT Tools different from CyberChef?**
A: CyberChef is more powerful, supporting operation chains (stringing multiple transforms together) and 300+ operations — great for security analysis and complex data processing. IT Tools focuses on UX and everyday developer utilities, with more intuitive operations. You can use both.

**Q: Is data secure?**
A: All tools run locally in the browser — no data is sent to any server. That's the main advantage of self-hosting IT Tools over using online tool websites.

**Q: Can I add custom tools?**
A: IT Tools is built with Vue.js — fork the project to add custom tools. The community is also continuously contributing new ones.
