An offline hotel PMS that never blocks the front desk
Most PMS platforms are cloud-only: no internet means no check-ins. ViharaOS runs a native desktop client that keeps operating locally and syncs automatically the moment your connection returns.
An internet outage should not stop your front desk
Browser-based, cloud-only PMS software depends entirely on a live connection. In towns with unreliable broadband or mobile data, that single dependency turns routine outages into operational emergencies.
A guest is standing at the desk and the check-in screen will not load.
Card payments cannot be reconciled with the folio because the browser tab lost its session.
Staff fall back to a paper register "just for today" — and that data never makes it into the system.
Power cuts and monsoon-season connectivity drops happen on a schedule cloud PMS vendors do not plan for.
How the offline-first architecture works
ViharaOS Desktop is a native app (Tauri + a local SQLite database) — not a browser tab pointed at a server. Your data lives on the machine first.
Local-first reads and writes
Reservations, check-ins, folio charges and room status are written to a local database instantly, whether or not you are online.
Automatic background sync
When a connection is available, changes sync to the cloud backend in the background — no manual "upload" step, no blocking dialog.
Conflict-aware sync
If the same property is edited from two devices while offline, ViharaOS reconciles changes when both come back online, flagging genuine conflicts (e.g. the same room double-booked) for staff to resolve rather than silently overwriting.
Small footprint, fast boot
The desktop client is built to install quickly and start in seconds on modest front-desk hardware, not just high-spec machines.
What happens during an outage
Connection drops
The desktop app detects the loss and switches to local mode automatically — no action needed from staff.
Operations continue
Check-ins, check-outs, folio postings and housekeeping updates are all recorded locally in real time.
Connection returns
The app reconnects in the background and begins syncing the queued changes to the cloud.
Sync completes
Other devices and the web dashboard reflect the synced state; any real conflicts are surfaced for review.
Who needs an offline-first PMS
Pilgrim and hill-station towns
Areas where mobile data and broadband are seasonal or inconsistent.
Properties with frequent power cuts
Hotels that cannot guarantee uptime for a router or ISP connection.
Multi-building properties
Campuses where Wi-Fi does not reach every front desk or annex reliably.
Anyone burned by a cloud-only PMS outage
Teams that have already lost a booking or a check-in to a dead connection.
What it's good at, and where it has limits
Where ViharaOS helps most
- Front desk keeps working through outages — no blocked check-ins or lost bookings.
- Fast local reads/writes; no waiting on network round-trips for routine actions.
- Automatic sync in the background once connectivity returns.
- Runs on modest hardware already at the front desk.
Where it has limits
- A device that is offline for an extended period will only reflect changes made on that device until it reconnects — other properties/devices will not see those updates in real time.
- Genuine double-booking conflicts across offline devices are flagged for manual resolution, not automatically guessed at.
- The desktop client currently supports Windows and macOS only.
- Some cloud-dependent features (e.g. live channel-manager sync) require an active connection to take effect, by definition.

They are saved locally immediately and queued for sync. As soon as the app detects a connection, it syncs those bookings to the cloud backend automatically — no manual export or re-entry needed.
