# Portless - Named .localhost URLs Replace port numbers with stable, named `.localhost` URLs for local development. For humans and agents. > **Note:** By default, use HTTP (`http://myapp.localhost`). Only enable HTTPS (`--https` or `PORTLESS_HTTPS=1`) if the user specifically requests it (e.g., for OAuth, secure cookies, or HTTPS-only features). ## Why Portless? Local dev with port numbers is fragile. Portless fixes that by giving each dev server a stable, named `.localhost` URL. | Problem | With Ports | With Portless | | -------------------------- | ------------------------------------------------------- | ----------------------------------------------- | | **Port conflicts** | Two projects on :3000 = EADDRINUSE | Auto-assigned ports, named URLs - no collisions | | **Memorizing ports** | "Was the API on 3001 or 8080?" | Always `http://api.localhost` | | **Wrong app on refresh** | Stop one server, start another on same port = confusion | Named URLs eliminate this | | **Monorepo chaos** | Every service needs a unique port | Distinct hostnames for each service | | **Agent confusion** | AI agents guess/hardcode wrong ports | `http://myapp.localhost` is deterministic | | **Cookie/storage clashes** | Cookie...
