Pipenet – A Modern Alternative to Localtunnel
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
In plain words
Pipenet is a tunneling tool that exposes local applications to the internet, similar to Localtunnel but built to work in restricted environments. Unlike its predecessor, it uses multiplexing over a single port, making it compatible with platforms like Fly.io and strict firewall configurations. Written in TypeScript and fully open-source, Pipenet can be self-hosted or accessed through a public instance at *.pipenet.dev without setup overhead.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
