In 2026, the world of Customer Relationship Management (CRM) continues to evolve — but one thing remains clear: businesses want freedom, transparency, and control over their data.
That’s why open source CRM software has become the go-to solution for small businesses, startups, and nonprofits alike. Unlike paid CRMs, open source tools offer customization, cost savings, and ownership, without vendor lock-in.
Whether you’re in the USA, UK, or anywhere worldwide, this guide explores the best open source CRM software for 2026, including free and self-hosted options ideal for growing companies.
What Is Open Source CRM Software?
Open source CRM software is a type of CRM system whose source code is available for anyone to view, modify, and distribute. This gives businesses full control to:
- Customize workflows and features
- Integrate third-party tools

Unlike proprietary CRMs (like Salesforce or HubSpot), open source CRMs are often free or low-cost and allow on-premise hosting (self-hosted) for better privacy and compliance.
