Are you looking for free open source CRM software?

For sales teams that are customer-centric along with marketing departments, CRM applications can be fundamental for lead management at 360 degrees to achieve greater productivity from end to end, optimize speed in managing the sales process to improve customer loyalty and boost customer engagement with an increase in ROI.

This is where we can begin to consider Open Source CRM solutions that may be a good option to integrate from an economic point of view.

In which case would this really be a good choice? Which Open Source CRM solutions are truly worthwhile? Let's assess the best free open source CRM for small businesses in the following article.

What is a free Open Source CRM?

A free CRM refers to software that helps you organize your relationship with potential and current customers for increased customer satisfaction. The term "Open Source" means that the software meets certain characteristics such as:

  • The computer program cannot be sold.
  • The software code is accessible and can be modified.
  • Applications derived from Open Source CRM must be available.

The Pros and Cons of Open Source CRM


  • The software itself is free of charge. It can be downloaded directly from the community website.
  • Developments are fast due to the large community of developers.
  • User communities are very engaged on forums and answer your questions when they are not already processed.


  • Deployment, updates, maintenance and hosting at your expense. The time spent doing these operations is long and the journey is full of technical pitfalls. This time spent often costs more than a license from a proprietary CRM.
  • The functional coverage of open CRM is very high and sometimes too much for the needs of a very small business.
  • The ergonomics of free CRM is often lagging behind proprietary software. However, this is less and less the case.

Open Source CRM


CiviCRM Software

Created: 2004

Number of downloads: 11,022 active platforms

Technology: PHP, MySQL, need to have Drupal, Joomla or Wordpress

CiviCRM is an interactive CRM designed for the very specific needs of non-profit organizations. Among the features that are not found in a traditional CRM are: member management, donations and family reunification. CiviCRM therefore does not manage clients but members or benefactors. It is quite possible to adapt CiviCRM to a commercial context but this practice is not recommended because it is likely to create bugs. Finally, CiviCRM can only be used in addition to a CMS (Drupal, Joomla! or Wordpress) and not independently as any other CRM. CiviCRM is used by NGOs such as Amnesty International and Creative Commons.

SugarCRM Is No Longer Open Source

You will no longer find SugarCRM in this ranking as it has not been an Open Source product for several years now. The company is currently positioning itself as a direct competitor of Salesforce. That being said, vtiger CRM and SuiteCRM has taken over this exciting challenge with great success.

Paid CRM Alternatives to Free CRM

Naturally, if the free tools do not offer the features you are looking for, you can always opt for a paid sales force automation solution. In this case the variety is certainly greater and you can also find a cloud-based CRM system. If it is the economic investment that is frightening, companies often offer 30 days of free trial time so that you can get familiar with the tool before you invest in it.

Here are some popular CRM software solutions:

  • Zoho CRM
  • Salesforce
  • Microsoft Dynamics

From CRM to ERP, There Is Only One Step

Many CRMs are moving towards ERP and most ERPs have a customer relationship management module. In fact, if you do not find what you are looking for in the above selection then the CRM you are looking for may be an ERP. The list of Open Source ERPs offering CRM such as Dolibarr, Compiere, etc. is large enough to offer more choices and opportunities for your company.


Open Source CRMs are a good option from an economic point of view if their implementation and maintenance is simple. This depends mainly on the product and your team. The advantage of free CRM is first and foremost functional because the development rate is faster than that of a proprietary CRM. It is also possible to use a specialized hosting provider that will make CRM available on the Cloud to help you with technical issues. The list of trusted Open Source CRMs is relatively small, which is why open source ERPs with a CRM module should be considered in the list of available options.
