# CapyInn – Desktop PMS software for mini hotels in Vietnam

CapyInn is a desktop PMS software specifically designed for mini hotels, guesthouses, and small-scale homestays in Vietnam. The product follows an offline-first approach: all data is stored and processed locally on the computer, helping accommodations reduce dependence on complex cloud systems while ensuring daily operations – from reception, housekeeping, payments to night audit – run smoothly and efficiently.

## Core Features

CapyInn focuses on practical operations at the front desk:

- OCR for CCCD/CMND in Vietnam for quick guest information entry

- Visual room layout to assist with check-in, check-out, room booking and extending stays

- Monitoring room rates per night, deposits, payments, and receivables

- Support for multiple guests in a single booking

- Management of cleaning status, maintenance notes, and end-of-day night audit

- View revenue reports, expenses, and export data quickly

As a desktop application, the deployment process is very straightforward: install the software, complete the initial onboarding (hotel information, room types, room numbers, basic rates), and then it can be put into operation immediately. A demo video has been uploaded on YouTube for users to easily visualize how to use it in practice.

## Expanding Through MCP: Automation and AI When Needed

CapyInn does not stop at the core PMS. The software comes with a built-in MCP server with operational data query commands such as room status, guests currently staying, check-in/check-out schedules, and metrics needed for front desk or management. From this MCP layer, business owners can connect with OpenClaw or n8n to build customized automation workflows as needed.

For example, for businesses that do not yet have a Zalo OA account, CapyInn can connect with a self-deployed Zalo chatbot based on zca-js and a customized n8n node: listening for incoming messages, calling CapyInn’s MCP query, and then automatically responding to common questions such as “Do you have any rooms available today?”, “What’s the room rate?”, “What time is check-in?”, or “Do you have a room for 2?”. This way, business owners have a semi-automated consulting channel directly on their personal Zalo without needing to invest in OA from the start.

For businesses willing to invest more systematically, CapyInn also supports integration with official Zalo OA: using OA to receive customer conversations, while n8n handles steps such as sending check-in information, reminding about deposits, confirming bookings, or pushing internal requests to other operational processes. Depending on the model, the same layer of data from CapyInn can simultaneously serve the consulting chatbot, front desk workflow, and post-sale logistical tasks.

## Installation and System Requirements

CapyInn is an offline-first desktop PMS software that runs completely locally and does not rely on cloud services. Once installed, users can immediately utilize all essential features: room management, check-in, check-out, stays, payments, and end-of-day reconciliation.

Currently, CapyInn releases installation files for Windows and Linux through GitHub Releases. For macOS, users need to download the source code and build it themselves to run the application.

Basic Installation Process:

1. Download the release that matches your operating system.

2. Install the application on the reception or management computer.

3. Open the software and complete the onboarding: enter property information, create room types, declare the room list, basic rates, and admin account.

4. Start using it for daily operations.

As data is stored locally, this model is particularly suitable for small accommodations wanting to control data on-site, reduce reliance on the internet, and avoid complex cloud systems. Extensions like OCR, MCP, OpenClaw, or n8n are optional configurations when needed, and not mandatory for the core software to operate.
