Show HN: Port Zero – How I learned to stop worrying and love PORT=0

Category: devtools

Tags: local-development, tunneling, collaboration, feedback, dev-experience

Score: 5.3/10 (Innovation: 5, Technical: 5, Documentation: 3, Utility: 6)

Port Zero provides stable, shareable domains for local development ports, enabling collaborators to access a live app without deploying or cloning. It adds name-based authentication and inline feedback comments directly on the running app, streamlining quick iterations. The concept addresses a real pain point in local dev sharing but faces competition from established tunneling tools.

Target audience: frontend and backend developers, designers, product managers
