    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 :)

    Pico is an open-source alternative to Ngrok. Unlike most other open-source tunnelling solutions, Pico is designed to serve production traffic and be simple to host (particularly on Kubernetes). Upstream services connect to Pico and register endpoints. Pico will then route requests for an endpoint to a registered upstream service via its outbound-only connection. This means you can expose your services without opening a public port. Pico runs as a cluster of nodes in order to be fault tolerant, scale horizontally and support zero downtime deployments. It is also easy to host, such as a…

    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:…

    zrok is a fun incubator project I've been working on over the last six months. The goal was to see how we could build a tool in the genre of "reverse-proxy-meets-streamlined-sharing", like a lot of the other tools that you probably know, already love, or use regularly. I've been part of the OpenZiti team for years now, and it was an obvious choice to use OpenZiti as the foundation for zrok. We already know OpenZiti inside and out, and we know how it can best be leveraged to build a tool like this so that it's secure, zero-trust, and scalable, all while still keeping it friction-free and easy…

    I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues. The two best things about it are: - It's easy to install if I can access pip in the container - It makes a compelling screenshot (which helps me communicate with coworkers.) With those two lessons in mind: Here is Sping! Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS) Two good things about it: - It's easy to install if you have pip.

    Hey HN! localtunnel's server needs random ports per client. That doesn't work on Fly.io or behind strict firewalls. We rewrote it in TypeScript and added multiplexing over a single port. Open-source and 100% self-hostable. Public instance at *.pipenet.dev if you don't want to self-host. Built at Glama for our MCP Inspector, but it's a generic tunnel with no ties to our infra. https://github.com/punkpeye/pipenet

    Demo: https://aether.saphal.me GitHub: https://github.com/saphalpdyl/Aether Aether is a multi-BNG (Broadband Network Gateway) ISP infrastructure lab built almost from scratch that emulates IPoE IPv4 subscriber management end-to-end. It supports IPoE/Ipv4 networks and runs a python-based vBNG with RADIUS AAA, per-subscriber traffic shaping, and traffic simulation emulated on Containerlab. It is also my first personal networking project, built roughly over a month. Motivations behind the project I'm a CS sophomore. About three years ago, I was assigned, as an…
