Post Description

I wanted to do something fun in Elixir and ended up building a localhost tunnel. I've used ngrok for showing my local dev to others and testing webhooks, but figured I'd see what I could make myself.

npx runlocal 3000 - Gives you a public HTTPS URL forwarding to localhost. No account, no config.

It's a single Phoenix app using WebSocket to relay HTTP in real time. No database, no Redis. Fully open source, EU owned and hosted, MIT licensed. Please give feedback
