Krayin CRM is a free, open-source customer relationship management system designed for small-to-medium businesses and enterprises. A CRM (Customer Relationship Management) tool is software that helps a business track and manage all of its interactions with customers and potential customers, things like contact information, sales leads, communication history, and deal pipelines. Krayin handles the complete customer lifecycle: capturing leads, managing contacts, tracking deals, and communicating with customers. It includes an admin dashboard, custom data fields, email parsing (to automatically create records from incoming emails), and support for modules you can extend or customize. You would use Krayin if you run a business and want a self-hosted alternative to paid CRM tools, giving you full control over your data. It can be installed on your own server, or you can use their managed cloud hosting option if you prefer not to handle the infrastructure yourself. A multi-tenant SaaS version is also available for companies that want to offer CRM to multiple separate clients from one installation. The application is built with Laravel (a PHP web framework) for the backend and Vue.js for interactive front-end elements. It requires PHP 8.2 or higher, a MySQL database, and a web server such as Apache or Nginx. It is licensed under the MIT license.
