Best open source CRM software

The best free and open source alternatives to Salesforce or Microsoft CRM software


When it comes to customer relationship management (CRM) software, has quickly grown into the dominant player with its software-as-a-service (SaaS) model. With this popularity comes cost, and alongside other proprietary big players like Microsoft Dynamics 365 and Oracle CRM, prices can be anything between £20-£240 per user.

For the more cost-conscious organisations there are open source solutions for storing that all important customer relationship data, and solutions that are far more configurable.

So what are the open source CRM alternatives? Here are some of the best on the market.
