Self-Hosted HTTPS Tunnel in 300 LoC with Go, Caddy, and Cloudflare

In plain words

A lightweight HTTPS tunnel solution built with Go, Caddy, and Cloudflare in approximately 300 lines of code. It enables developers to expose local applications securely over HTTPS without complex configuration. The project is designed for developers who need quick tunneling capabilities with minimal setup and a small codebase that remains easy to understand and modify.

From the sources

TL;DR: I built a lightweight, self-hosted HTTP tunnel that turns localhost into a public HTTPS URL. No paid plans, no secret black boxes. Just one Go binary, Caddy with wildcard TLS, and a $0/month Oracle Cloud VM. GitHub repo Why I Built It My development workflow lives mostly on a free Oracle Cloud VM: SSH, Neovim, tmux—the usual hacker starter pack. I tried many ways to easily expose my local a

  An Almost Free, Open Source TURN Server2025 · github.com · ▲122

  Hi HN, I have been messing around with WebRTC for a few years now but when it comes to the TURN server I never quite got to my gold standard of free, self-hosted and open source. I decided to give it a go using Oracle Cloud Infrastructure's free tier, meaning that my total spend got down to domain name hosting. I know plenty of people have been burnt by Oracle in the past, but I have had servers running on the free tier for 5 years now without so much as a hiccup. Regardless, the concepts will be the same using any cloud based server. This is the first time I've written up an end-to-end…

  I built it for myself because ngrok didn't let me add one more domain unless I paid $12 more. I probably should've looked for alternatives before building my own, but my grudge got in the way . Once I started, I wanted to make it better than the other options. Silly, I know. No one probably cares. I plan to open source it sometime next year because I’ve got other projects to finish first. It's free until I deplete my cloud credits, then it will switch to a tier-based model with a free option.

  Talanoa▲340

  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 hardware processor that runs Python▲983

  Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
