portless

Why we included this project

Local development usually means juggling port numbers, and every restart can hand your app a new URL. Portless pins each project to a fixed .localhost address with HTTPS and HTTP/2 on by default, so the same URL keeps working across runs. It also handles the setup that normally gets in the way: it generates and trusts a local CA, injects the right --port and --host flags for frameworks that ignore the PORT variable, and gives each git worktree its own subdomain. That fixed endpoint is what makes it useful for AI agents and automation, which need a dependable address to call while developing rather than one that shifts between runs. Monorepos get a single config, and in CI it fails with a clear error instead of hanging on a prompt, so teams can adopt it without hand-managing a proxy.
