Cal.com includes an availability troubleshooter for owners. Booking Guard adds an external layer: it reads the public booking path a visitor receives, confirms supported availability states, and can put a protected URL in front of the raw scheduler link.
ShadowOrders product: Booking Guard. This page describes one specific use case; the technical boundary is the same as the underlying product.
A booking page can be affected by availability, calendar connections, booking limits, notice windows, buffers or service health. Booking Guard does not rewrite those settings. It watches the public outcome and only switches to fallback after repeated confirmed failure.
Paste a public cal.com link. The checker verifies the provider flow without credentials and reports the deepest safe stage it can confirm. Supported links unlock the annual protected-link plan.
No Cal.com credentials and no appointment creation. The public check is observational; owner-side configuration changes remain in Cal.com.
