portless

Vercel Labs tool that replaces localhost ports with stable, named .localhost URLs

Aboutgithub.com

portless replaces port numbers with stable, named .localhost URLs for local development, for people and agents. You run the dev command through portless and get an address such as myapp.localhost. It uses the Apache 2.0 license and has about 12,700 GitHub stars.

Install

npm install -g portless

For an agent

Use it so agents and teammates reach local apps by name, not by port. Set it up once per machine.

Why it is here. It removes port confusion from local development.
