Hollow Sentinel documentation

Hollow Sentinel is operational intelligence for Shopify — not another analytics dashboard. It watches your store, remembers what changed, compares metrics to your baselines, and delivers a daily briefing you can act on in minutes.

Start here

• Quick start — install, pick a plan, confirm your first briefing
• Getting started — OAuth, billing, Command center navigation, and intelligence modules
• Email alerts — Resend API key, from address, and recipients in Settings (Starter+)
• Plans and limits — Starter, Growth, Scale, and Enterprise (what ships today vs roadmap)
• Vs alternatives — how Sentinel compares to analytics and alert apps
• Connect Slack — daily briefing delivery to a team channel (Growth+)
• Connect Klaviyo — Placed Order volume vs 7-day baseline (Growth+)

Command center (home)

Command center is your daily operator view. It shows a learning banner during the 14-day baseline period, six intelligence module statuses (Revenue Shield, Operations Radar, and more), today's operator summary, the setup or daily briefing, executive briefing on Scale, health scores with peer benchmarks on Growth+, and recommended Engine playbooks when both apps are installed.
