Introduction
In a world where customer relationships define business success, CRM (Customer Relationship Management) systems have become essential. But not every business can afford high-priced CRM tools with ongoing subscription fees. That’s where open source CRM solutions come in.
Open source CRMs offer powerful features at zero cost, with full customization flexibility—making them ideal for startups, small businesses, and developers.
What is an Open Source CRM?
An open source CRM is a customer relationship management platform whose source code is publicly available. This allows businesses to modify, customize, and extend the CRM software based on their specific needs.
Unlike proprietary CRMs, open source options are:
- Free to use
- Highly customizable
- Community supported
- Free from vendor lock-in
