WHERE JACK HQ IS REACHABLE FROM

localhost in any iOS Shortcut, Twilio webhook, or remote tool will fail every time you're off Wi-Fi, every time your Mac's IP shifts, every time npm run dev stops. Below: every URL this server is reachable at right now, ranked by reach. Pick the highest tier you have available and use that URL.

detecting reachable URLs…
TIER 1
mDNS (.local)
Reach: Same Wi-Fi only
Cost: $0 · 0min · already works
When: Today's quick fix

iOS supports .local hostnames natively via Bonjour. The .local hostname is stable — it doesn't change when DHCP renews your IP.

TIER 2
Tailscale + Serve
Reach: Anywhere your phone has internet (HTTPS)
Cost: $0 personal · ~5min setup
When: The right answer for personal use

Install Tailscale on Mac + iPhone (same account), then 'tailscale serve --bg --https=443 http://localhost:4280'. Get a TLS URL that works from cellular, hotel Wi-Fi, anywhere — tailnet members only, never public.

TIER 3
Tailscale Funnel
Reach: Public internet (HTTPS)
Cost: $0 · ~10min · needs ACL opt-in
When: For Slack + Twilio webhooks

After Serve is on, add 'funnel' to the node's ACL attrs at login.tailscale.com/admin/acls, then 'tailscale funnel --bg 443'. Same URL, now reachable from Slack/Twilio. Treat the Mac as exposed — auth every endpoint.

AUTO-RESTART NPM DEV (Tier 2.5)

Even with Tailscale, your dev server stops if you quit the terminal or the Mac restarts. There's a LaunchAgent template at /Applications/Jack-HQ/install/com.jack-hq.web.plist that auto-starts npm run dev at login + restarts within 10s on any crash. Install commands are in INSTALL.md at the project root.
