Why CM Free?

Designed for small apartment owners who want full control over their reservations, occupancy and integrations — without depending on expensive cloud systems.

JSON Based

No database required

All reservations, occupancy and integrations are stored as portable JSON files. Easy backups. Easy migration. Easy recovery.

Fast UI

Visual calendar workflow

Built around a fullscreen occupancy calendar with layered views, fast editing, reservation management and onboarding help.

Self Hosted

Your data stays yours

Run locally, on VPS, mini PC, Ubuntu node or shared hosting. No forced SaaS lock-in.

AnyDesk Mode

Made for real people

Interactive onboarding guides help non-technical users learn the system directly inside the real interface.

Guest Chat (external module)

A private channel, not another app

Not part of CM Free itself - Guest Chat is a separate, standalone connector module, plugged into this CM install here to demonstrate how the CM Ecosystem's modularity works in practice.

Guests scan a code and enter the PIN they already have for the door - no account, no app install. This instance reads reservations straight from this CM install; the same module also runs cross-host over the new CM Bridge Protocol, unmodified.

This demo PIN is shared and intentionally public - everyone testing it lands in the same conversation. A real guest gets their own private PIN.

Minimal Ubuntu deployment

CM Free / CM Plus works even on lightweight Ubuntu mini-PC deployments. Perfect for small hospitality offices and local installations.
