Sugar CRM

Sugar CRMis the most famous, as well as the most used, since it brings with it a large number offunctionalitiesthat allow us to have a verycomplete CRMwithin our reach thatyou can easily install through Plesk applications.

We must mention that despite being “Open Source”,Sugar CRM also has some limited options that are only offered with its paid version. Therefore, it is not a 100% free software, however, the version that is free brings many tools that we can hardly take advantage of all of them, but if we still want more, we can always end up going through the checkout to have all the Sugar CRM functionalities.

To install Sugar CRM from Plesk that we offer at Hostinger, you just have to go to the Plesk Applications section, click on“All available applications”on the left , and then on“Back office”.

And in this way a button will appear on the right side toinstall in our Plesk Sugar CRM.

Dolibarr ERP CRM

As well indicated onDolibarr ‘s own page ; This softwareis an open source ERP and CRM for companies(SMEs, Large Companies, Freelancers, Foundations).

Dolibarr is much easier to use than Sugar CRM. It is especially focused on SMEs, as we have mentioned before. Also,add an “enterprise resource planning system”or what is the same an Enterprise Resource Planning (abbreviations of “ERP” in English). Therefore,its biggest advantage is the union between CRM and ERP. Being so flexible makes it a benchmark.

Dolibarroperates in a modular way so it is very configurable. That is, each section of the software can be enabled and disabled to leave only the ones that are being used. In addition, it is very similar to WordPress in terms of widgets and plugins, since ithas a large number of third-party modules and pluginswith which to increase its functionality and features.


vTiger Best Open Source CRMs
Best Open Source CRMs: vTiger

With more than5 million downloads,vTigeris considered another of the famous CRMs, especially for those companies that purchase their paid license. In fact,this software started as an offshoot of Sugar CRMmore than 10 years ago.

vTiger has a free part (open source), but it is quite limited compared to the paid version. Maybe that’s why Dolibarr is in second place and not vTiger. Users tend more to look for free options, while companies opt for the opposite and that is why many prefer vTiger or directly bet on Sugar CRM.

Now,what does vTiger offer? The possibility of adapting to all types of companies, but above all its simplicity of use.

It is a tool that focuses onsales optimization, also providing numerousintegrations, regular updates, more than 25 languages, user access control, large community,etc.

Fat Free CRM GitHub

For this fourth position we have left themost valued CRM project within the GitHub platform. In fact, it has to be downloaded from that platform and not from its official website.

Fat Free CRMis very interesting, not only because it is yet another Open Source CRM, but because unlike other projects or applications, it is based on Ruby on Rails instead of PHP.

This software offers group collaboration, campaign management and leadership, contact lists, and opportunity tracking.

Thegoal of Fat Free CRM is to stimulate innovation by providing a clean code base that developers can easily modify.

UpiCRM – ¡CRM For WordPress!

In the fifth and last position of the top we have decided to mention a different tool, as we have commented at the beginning of this same publication. Instead of another Open Source CRM program, we bring aWordPress plugin with which you can turn this popular website and blog platform into a powerful CRM.

WordPressis not prepared out of the box to manage relationships with a company’s customers, but since it has plugins for almost anything,if we want a CRM we only have to install a plugin for it.

This is whereUpi CRMfor WordPress comes in, afree plugin to turn this CMS into a powerful CRM. In addition, it has very interesting features, but in principle what is achieved isto create a database of potential customers, through contact forms, to be able to follow up on themand not leave them “abandoned”.

UpiCRM is compatible with themost famous WordPress form plugins, such as:

  • Contact Form 7
  • Elementor Forms
  • Wp-Forms
  • Caldera Forms
  • Ninja Forms
  • CForms
  • Gravity forms

Once the plugin is activated, in the WordPress main menu, anew section called “UpiCRM”will appear from which you can access the configuration.


Choosing an open source CRM is a good option for your business since its adaptability and flexibility help cover most of the needs you may have, in a personalized way, in addition to reducing costs or using it for free.
