A simple self-hosted ngrok alternative
This is a proof of concept utility which allows you to expose local services to the internet at large: https://github.com/skx/tunneller In short it is a simple ngrok alternative, which you can self-host. Because it is a proof of concept it hasn't been tested extensively, but it seems like it will solve my immediate-needs. Of course it needs test, and structure added. But feedback can't hurt :)

In plain words
Tunneller is a self-hosted utility that exposes local services to the internet, functioning as an alternative to ngrok. Designed for developers who want to tunnel local applications without relying on third-party services, it allows users to host the tool on their own infrastructure. As a proof of concept, it addresses immediate tunneling needs but requires further testing and refinement before production use.

- ASA 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▲340Hi 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…
