Loophole is a free service that enables developers to instantly create secure public HTTPS URLs for locally running web servers, directories, and services without port-forwarding, firewall setups, or dynamic DNS.

---

🚀 Overview

Loophole solves the common developer pain point of securely exposing local services to the public internet. Whether for demos, webhooks, beta testing, file sharing, or accessing personal cloud servers like on a Raspberry Pi, it eliminates the hassle of network configurations, NAT traversal, and security risks associated with traditional methods.

It's built for developers, indie makers, self-hosters, and teams needing quick, reliable tunneling solutions.

The project was created as a simple, completely free alternative to tools like ngrok, emphasizing end-to-end encryption, unlimited usage, and ease of use with CLI or desktop clients.
