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 apps for testing webhooks, sharing demos, and collaborating with friends.
