Named HTTPS .localhost URLs with portless (v0.15.x). Eliminates port collisions, gives agents stable URLs, adds branch-named subdomains for git worktrees, LAN mode (--lan), and Tailscale sharing. Use when setting up a local dev environment or testing from phones and tablets on the same wifi. Do NOT use for production deployments, CI environments (set PORTLESS=0), or DNS/hosting configuration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Portless Integration
Named `.localhost` URLs for local development. Replaces `localhost:3000` with `https://myapp.localhost`.
> **Full CLI reference**: Load `Read("references/upstream.md")` for complete command docs.
## New in 2026-04 → 2026-07 (portless 0.10.x → 0.15.0)
- **`portless doctor` (0.15.0)** — read-only diagnostics that check Node.js, the state directory, proxy liveness, route entries, hostname resolution, HTTPS CA trust, and LAN prerequisites, then print suggested fixes. Run it before filing an issue or when a `.localhost` URL won't resolve.
- **HTTP/2 Host forwarding fix (0.15.0)** — the proxy now forwards the HTTP/2 `:authority` as `Host` to HTTP/1.1 backends, fixing apps that read `Host` and previously saw `127.0.0.1` for browser traffic. `--force` takeover cleanup now removes only routes still owned by the exiting process, so a forced takeover no longer deregisters the new owner's route.
- **`--ngrok` flag (0.14.0)** — share an app publicly via ngrok while local access keeps its `.localhost` URL. Pair with the existing Tailscale/Funnel options when you need a public URL without giving up the named-subdomain dev experience.

How to install
mdr add yonatangross/orchestkit/portless@sha256:0bb5e96059c5f7b5The line at the top of this page pins the label v1.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
