Krayin

Krayin is an open-source, self-hosted customer relationship management framework designed for small to medium enterprises and larger organizations to manage the entire customer lifecycle. The software is deployed as a web application on a server using Apache or NGINX, providing a centralized hub for sales tracking and marketing automation.

Built with a modular architecture, Krayin allows businesses to organize their customer data and sales pipelines. It is available as a standalone installation for a single organization or as a multi-tenant SaaS solution. The multi-tenant configuration allows multiple separate businesses to use a single application instance while keeping their respective data isolated and secure from other users.

The application is developed using the Laravel PHP framework and Vue.js, making it accessible for developers who wish to customize the core logic or build additional modules. To run the system, a server requires at least 3 GB of RAM, PHP 8.3 or higher, and Composer 2.5 or higher. For data persistence, it supports MySQL 8.0.32 or higher. The installation process involves configuring environment variables for the application URL, mail settings, and database parameters before executing the installation command.

Beyond the core CRM, the platform includes specific extensions to bridge communication gaps. The WhatsApp extension enables administrators to generate leads directly through their phone numbers, while the VoIP extension allows users to perform inbound routes and make trunk calls over a broadband internet connection. This makes the system suitable for e-commerce businesses that need to scale their communication and lead management.

Krayin is a flexible CRM framework for businesses that require a self-hosted environment for customer data management.
