What is GoPort?

GoPort is an open-source alternative to ngrok and jprq that turns local applications into publicly accessible HTTPS endpoints.

Whether you're testing webhooks, sharing a demo, or exposing an API, GoPort gives your localhost a public URL in seconds — without port forwarding, firewall changes, or a public IP.

Built for developers, GoPort makes it easy to expose services running on your machine while keeping setup simple and infrastructure under your control. It uses a persistent multiplexed connection to efficiently route traffic between the public internet and your local application.

Unlike many hosted tunneling services, GoPort can be fully self-hosted, allowing teams to manage their own tunnels, domains, and infrastructure without vendor lock-in.

How it works

1. Authenticate the CLI

   goport auth <token>

   Authenticate the CLI with your GoPort account and connect it to your server.

2. Start a tunnel

   goport http 8080

   GoPort opens a secure outbound connection and instantly creates a public HTTPS URL for your local application.

3. Use a custom subdomain

   goport http 8080 --custom myapp

   Request a memorable URL for your tunnel:

   https://myapp.goport.uz

4. Generate a new URL

   goport http 8080 --reset

   Discards the current subdomain and creates a brand-new public URL.

5. Monitor traffic in real time

   After connecting, GoPort launches a local dashboard where you can inspect incoming requests, responses, tunnel status, and latency.

   

6. Route traffic to localhost

   When someone visits your public URL, GoPort forwards the request through a secure tunnel directly to your local application.

7. Disconnect cleanly

   Press Ctrl+C at any time to close the tunnel. GoPort automatically removes the active session and releases the URL.

Installation

macOS

Install via Homebrew:

brew tap muhammad-deve/goport
brew install goport

Windows

Install via Chocolatey:

choco install goport

Linux

Install with the official installation script:

curl -fsSL https://github.com/muhammad-deve/GoPort/releases/latest/download/goport-linux-amd64 -o /usr/local/bin/goport && chmod +x /usr/local/bin/goport

Verify Installation

goport --version

You should see the installed GoPort version printed to the terminal.

Technical Details

Why TCP + yamux instead of a plain HTTP proxy?

GoPort uses a persistent TCP connection between the CLI and the server, with request multiplexing powered by yamux.

A plain HTTP proxy opens a new connection per request and struggles with protocols that require long-lived connections, such as WebSockets and streaming responses. By multiplexing multiple streams over a single TCP connection, GoPort handles concurrency efficiently while remaining reliable behind NAT and firewalls.

The CLI also detects HTTP upgrade requests and switches to raw bidirectional forwarding when necessary, allowing WebSocket-based applications to work seamlessly.

One additional benefit is that GoPort preserves the original public Host header when forwarding requests to your local application. This keeps tools such as Swagger UI, OpenAPI, and host-based routing frameworks working exactly as they would in production.
