Krayin CRM is an open-source customer relationship management platform built on Laravel and Vue.js, designed specifically for small to medium-sized businesses and enterprises needing complete customer lifecycle management. It provides a modular, extensible foundation that combines the power of PHP’s Laravel framework with Vue.js for a dynamic admin interface. Unlike generic CRM tools, Krayin is tailored for e-commerce scalability with built-in features like custom attributes, email parsing via Sendgrid, and extensions for WhatsApp and VoIP integrations. The platform supports both single-tenant deployments and multi-tenant SaaS architectures, making it suitable for agencies managing multiple client accounts or businesses planning to offer CRM as a service.
Krayin CRM is not just a pre-built application but a framework—developers can extend its functionality through modules and custom plugins. Its documentation includes detailed guides for installation, configuration, and deployment, with official support for Docker, making it accessible to both technical teams and non-developer administrators. With over 20k GitHub stars and an MIT license, it’s a community-driven alternative to proprietary CRMs like Salesforce or HubSpot.
