Join us to compare the best open source CRM software so that you can make the right choice for your business or enterprise without wasting valuable time searching for information all over the internet.

Let's get started!

What is an open source CRM?

Open source CRM software is a kind of blueprint that allows users to create their own customised system tailored to their needs. In this sense, because the code is public, it is possible to edit and distribute it freely.

The aim of such open platforms is that, because any programmer can work on the code, the application is gradually improved until it is bug-free.

However, unlike most proprietary CRMs, you will need a programmer to modify the code of the open source solution or platform. If you have the right people on your team, an open source CRM platform is an excellent choice for your business.

Our selection criteria

In order to make the following comparison, Appvizer has taken into account the following selection criteria:

  • the versatility of the tool:
    • The automation of tasks,
    • Customer support,
    • sales funnel management,
    • contact management,
  • the added value proposition, either in terms of interoperability with other software or complementary functionalities;
  • the user-friendliness and ergonomics of the tool;
  • the integrability of the software,
  • the popularity among users,
  • the cost-effectiveness of the solution.


Who is the software for?

  • commerce and e-commerce,
  • banks and insurance companies,
  • call-centres,

Unlike Dolibarr, EspoCRM focuses mainly on customer relationship management, with advanced features and a rather nice design for open source.

Finally, the software has a cloud version subject to subscription, with various formulas.

Major strengths

It remains a free tool if you deploy it yourself locally. There is no limit to the size of your database, and you can develop the code according to your requirements.

In its basic version, EspoCRM covers most CRM needs:

  • sales automation
  • sales opportunity management,
  • calendar and shared calendar,

The software supports 26 languages.

It has a rather modern and responsive design.

EspoCRM is constantly evolving, with new features being developed every two months.

Our opinion on the software

Once again, the tool can be complex to learn at first sight... open source obliges.

Nevertheless, its functionalities and its possibilities of evolution will seduce companies that choose to turn to free software.

Finally, many EspoCRM users emphasise its intuitiveness and ease of use (once the tool has been installed and configured), due in particular to a rather pleasant interface and navigation.

Advantages of an open source CRM

These are some of the main advantages of choosing an open source CRM for your business:

  • Its flexibility and adaptability allow you to meet the needs of your business, as well as having a totally unique and customised tool.
  • Reduced costs, or even free of charge.
  • Most open source CRM applications can be managed at no additional cost.
  • Constant updates thanks to the 24/7 collaboration of numerous programmers.
  • The scalability of the tool allows it to grow with your business.
  • No long-term contracts are required, so if you don't find what you need in the software, you can look for another one without further commitment.
  • ownership of your CRM. Even if the software producers decide to abandon the project, your CRM will continue to work.

How to choose the best open source CRM for your company

As we have said previously, when choosing your open source software there are many features to take into account. However, these three are the most basic and relevant:

  • the cost of the tool: look for a tool that fits your budget.
  • the ease of customisation: even if you have a highly skilled team, a tool that is easy to customise will save you time, and therefore money.

Finally, remember to choose your tool according to your needs and taking into account the time you are willing to invest in developing and customising it, because time is money and this factor is essential when choosing.
