I am an engineer from Baku. I build things for fun. I hated opening five sites for simple tasks. I built a solution.

Now I have 36 tools in one HTML file. The file is 460KB. No npm. No build step. No server. It works offline on any machine.

Use these standard tools:

• JSON
• JWT
• Base64
• UUID
• QR codes
• Regex

Use these security tools:

• Packet Analyzer for Wireshark hex dumps
• CIDR Aggregator for subnets
• Config Diff for Cisco and nginx
• HTTP Headers Analyzer
• AES-GCM encryption
• SSH and RSA keys

Claude helped me write the code. I made the decisions. I chose the ideas.
