Shopify app
Run Shopify operations with Arcanum Engine.
Install ranked commerce playbooks, route alerts to your team, monitor store health, and track confirmed recoveries and playbook outcomes — without building every Shopify Flow from scratch.
What Engine delivers
A command center for repeatable Shopify operations.
Arcanum Engine gives merchants a clearer way to act on store signals: install proven playbooks, monitor operating health, send team alerts, and connect completed actions to measurable outcomes.
Command center
See store health, ranked opportunities, launch milestones, and next-best actions from one operating view.
Playbooks & systems
Install proven workflows for revenue recovery, inventory watch, customer retention, and merchandising ops — Slow Mover Digest, New Product Launch Checklist, Orphan Product Alert, and more.
Team alerts & Integrations
Send actionable alerts to the channels your team already uses, including email, Slack, Discord, Klaviyo, and more depending on plan.
Impact tracking
Track completed playbook runs, confirmed recoveries where available, cart value alerted for abandon playbooks, and execution history in Results.
From Installation to Impact
Launch the system, prove the result, then keep improving.
Start with guided setup, connect your team, activate the right playbooks, and use Engine’s results view to confirm what ran, what changed, and where to focus next.

05
Optimize & Scale
Monitor store health, discover ranked opportunities, and expand with additional playbooks, integrations, and industry packs as your business grows.
Engine vs DIY automation
When Shopify Flow is not the whole operating system.
Shopify Flow is useful for building individual automations. Arcanum Engine is built for merchants who want ranked playbooks, guided setup, team alerts, execution history, and directional impact tracking without designing every workflow manually.
| Need | Shopify Flow | Arcanum Engine |
|---|---|---|
| Build custom workflows | Strong | Guided through installed playbooks |
| Know what to automate first | Manual decision | Ranked opportunities |
| Track completed actions | Limited/manual | Built into results history |
| Connect actions to revenue | Manual reporting | Directional impact tracking (confirmed recoveries where available) |
| Team-ready operating view | Not the main purpose | Command Center included |

Common questions
A few practical answers about setup, Shopify Flow, integrations, plans, and how Engine fits into a merchant's existing operations.
Do I need Shopify Flow to use Arcanum Engine?
No. Engine is designed to help merchants install and manage playbooks without building every workflow manually. Shopify Flow can still be useful, but Engine gives your team a more guided operating layer.
Is Engine only for large stores?
No. Starter is built for smaller teams that want a clearer operating rhythm. Growth and Ops are better fits for merchants with more integrations, more alerts, or more complex workflows.
How is Engine different from Hollow Sentinel?
Hollow Sentinel watches the store and helps identify what changed, what is at risk, and what needs attention. Arcanum Engine helps install playbooks, route actions, and track results. Sentinel watches; Engine acts.
Can Engine replace custom automation work?
Sometimes. Engine can reduce the need for custom workflow builds by giving merchants installed playbooks and guided systems. More advanced AI automation, private integrations, or cross-platform orchestration may still be scoped as custom work.
What should I install first?
Start with the Quick Start Checklist. Connect alerts, activate one core playbook, run a test event, and verify your first result before expanding into additional systems.
