portless

portless is an open source developer tool that replaces traditional localhost port numbers with stable, human-readable .localhost URLs, simplifying local development workflows for both humans and AI agents. Instead of managing multiple numeric ports and dealing with conflicts, developers can assign named local endpoints that remain consistent across sessions and services. The project is especially useful in multi-service environments where remembering and coordinating port assignments becomes cumbersome. By automating routing and naming, Portless reduces cognitive overhead and improves clarity when running several applications simultaneously. It is implemented in TypeScript and designed to integrate smoothly into modern JavaScript and Next.js development setups.
