For humans and agents. **[Amit yadav](https://daily.dev/sources/0oywkpxarz5zwwfifwguq)** · [@amityadav](https://daily.dev/amityadav) · 39 upvotes · 2 comments ## Summary Portless is an npm tool that replaces numeric localhost port numbers with stable, named `.localhost` URLs for local development. Instead of `localhost:3000`, you get `myapp.localhost:1355`. It runs a local proxy daemon that routes named subdomains to randomly assigned ports, eliminating port conflicts, cookie/storage clashes, and hardcoded port issues. It supports HTTP/2 and HTTPS with auto-generated trusted certificates, works with most frameworks (Next.js, Vite, Express, Nuxt, etc.), and is designed to work reliably for both human developers and AI coding agents in monorepo setups. ## Full article daily.dev links to this article rather than hosting it.
