# Introduction

Welcome to the Krayin CRM Developer Portal. This section gets you from a fresh machine to a running Krayin install — and from there to AI-assisted development that understands Krayin's conventions out of the box.

Krayin is a free, open-source CRM framework for SMEs and enterprises, built on Laravel (opens new window), Vue.js (opens new window), and Tailwind CSS (opens new window). Try the live demo (opens new window) or browse the Krayin website (opens new window) for the marketing tour.
