history
Project history and usage
portless is a Vercel Labs local-development CLI that gives development servers stable, named `.localhost` URLs while assigning their underlying ports automatically.
Project history
portless was created by Vercel Labs to replace changing local port numbers with stable, named `.localhost` URLs. Its initial public feature set centered on a local reverse proxy, automatic port allocation, route discovery, and a CLI for listing named services.
Subsequent releases added project configuration, HTTPS by default, worktree-aware names, monorepo orchestration, operating-system startup services, and integrations for sharing development services over Tailscale and other tunnels.
Adoption history
Distributed through npm and Homebrew, portless targets contemporary multi-application development. Its official documentation describes support for popular development servers, JavaScript workspace package managers, monorepos, Git worktrees, Turborepo, and optional Tailscale sharing.
How it is used
Users wrap an explicit development command with a service name or run bare `portless` to discover the project's development script. The proxy allocates a backend port, exposes a stable HTTPS hostname, and injects appropriate port or host options for supported frameworks.
Configuration can live in a project-root `portless.json` or the `portless` key of `package.json`; both are optional because names and scripts can be inferred. Runtime route and TLS state is kept separately under `~/.portless`.
Why package nerds care
portless packages reverse proxying, local TLS, certificate trust, hostname routing, process management, and framework-specific port injection into one CLI. It is especially relevant to developers running several applications or agent-driven sessions concurrently, where hard-coded localhost ports become unreliable identifiers.
Timeline
- 0.1.0: Initial reverse proxy, named localhost URLs, route listing, and subdomain support.
- 0.3.0: Added `portless.json` configuration.
- 0.9.0: Made clean HTTPS URLs the default.
- 0.11.0: Added zero-argument startup and monorepo orchestration.
- 0.12.0: Added Tailscale Serve and Funnel integration.
