A native-Ruby port of Vercel's portless. Run your dev server through a local reverse proxy and reach it at https://<name>.localhost instead of a port — HTTPS by default, with an on-demand local CA, per-host certs, and a random backend port so you never collide on 3000/3001 again. Framework-agnostic; first-class with Rails.

A dry-cli binary plus a periodic launchd sync sweep that keeps every tracked repo (and whole GitHub orgs!) clean, on its default branch, and up to date — so anything downstream can clone from local disk instantly. macOS-only, GitHub-only (behind decoupled SCM/forge interfaces). Never destroys your work: dirty or diverged repos are reported, never touched. ヽ(•‿•)ノ✨
