🚀 Why Repo Glance?

🔰"Serverless & Secure"
Designed for enterprise engineers and privacy-conscious users. Your code is processed entirely within your browser's memory. No data is ever sent to external servers (except standard GitHub API calls if you choose to use them).

🔒"No Install Required"
Forget npm install, pip install, or environment setups. No node_modules hell. Just download the HTML file and open it.

💾"Ultimate Portability"
Carry the single index.html file on a USB drive. Use it on air-gapped machines or restricted corporate environments where installing CLI tools is prohibited.
