ProxyHub

In plain words

ProxyHub is an open-source tool that exposes local servers to the internet via public HTTPS URLs without requiring backend infrastructure. It enables developers to inspect requests in real time, mock API endpoints, and test APIs using built-in tools like an API composer and request inspector. The self-hostable alternative to ngrok operates entirely through command line with no account needed, making it suitable for developers building and testing applications locally or in teams.

Expose localhost to the internet — free, self-hostable ngrok alternative

Where 3000 is the port of your local server. Your local server is now accessible via a public HTTPS URL — that's it. Run proxyhub init and answer a few prompts — mode, port, token, and more. ProxyHub prints the equivalent CLI command before launching. Build and test APIs without a backend. ProxyHub ships with a built-in mock server and an API composer — no extra tools needed. Define API responses through a web UI — no backend server required. Supports exact, prefix, and regex path matching. Build and send HTTP requests from the inspector UI.

  A self hosted alternative to Ngrok2019 · ▲14

  Hi! I am sharing this because it may be useful to others. I created a simple Docker image that lets you easily expose a web app running locally on your dev machine to the Internet, via a proxy server. It is a self hosted alternative to something like Ngrok, which is a paid service if you use custom domains. A small server is cheaper than Ngrok (I use Hetzner Cloud and the cheapest server costs me 3€ per month). I use this method in particular to test HTTP verification with Let's Encrypt for a SaaS app running on my Mac. Hope this is useful :) Code:…

  Talanoa▲341

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
