portless
Replace port numbers with stable, named .localhost URLs for development
Visit portless.sh ↗What is portless?
portless is a development tool that replaces localhost port numbers with human-readable named URLs like https://myapp.localhost. It works with most JavaScript frameworks including Next.js, Express, Nuxt, Vite, and Astro, automatically injecting the correct port configuration. HTTPS with HTTP/2 is enabled by default, with automatic local certificate generation and trust on first run.
The tool is designed for both human developers and AI agents. It can be installed globally or per-project via npm, and integrates with package.json dev scripts. The project is built and maintained by Vercel Labs and includes support for AI agent tooling.
