With a low learning curve and easy set-up, it’s definitely one of the most approachable open source systems on the scene. It’s also one of the most popular.


Helpdesk support can be slow, as it is community-based. There’s also a moderate learning curve, and the free open source version’s integrations and features aren’t as developed as in paid versions. SuiteCRM doesn’t integrate with ERP software, so if you’re looking for holistic business process integration, it may not be the right choice.

Vtiger offers a cloud version and an open source version. Of course, if you opt for the open source version, you get to host it yourself and manage it all by yourself or hire a team.

After observing the pricing plan, the managed cloud version obviously looks promising. – with separate pricing plans for sales, marketing, and help desk. However, if you have the required technical expertise, the open-source version is good enough as well. Also, it was interesting to see a regional pricing plan for India because they have an office here.



X2CRM has an open source edition, which generously shares code through GitHub, SourceForge and Bitnami, thus encouraging anyone and everyone to customize it for their own purposes. The software can be downloaded right onto a webserver, but you can also get help when downloading it as part of a full stack version.

This open source edition employs many of the core modules from the general (non-open source) X2CRM platform, which is more geared toward larger enterprises rather than lean startups. 

Lighter operations can take advantage of X2CRM Open Source’s tools for marketing campaigns and pipeline and funnel management. There are email modules that include open email tracking and a feature to design workflow visualizations. X2CRM also has Android and iOS apps.


X2CRM is an up-and-coming platform and not the most widely used, so you may find it tricky to get the support you need through its small-ish community.


  • Open source version is free. 
  • Paid custom configuration and development solutions also available.


Espo Crm

Key Highlights:

  • The ability to switch to on-premise anytime.
  • Actively maintained open source (self-hosted) package.

EspoCRM is new to the scene and it is an impressive CRM software. You can download it for free and host it yourself or opt for the cloud solution where they do it for you.

They offer detailed documentation—in case you want to try it yourself. Furthermore, if you want to go with the cloud solution—you can always switch to on-premise anytime you want. I guess that makes it a bit more appealing.



Odoo is all about ‘extensible architecture,’ with a modular design that lets you mix and match different features. The open source Community Edition of Odoo CRM plugs into the 10,000+ apps in the vendor’s orbit, which are configured to integrate with one another seamlessly.

If you’re in retail, restaurants, or other brick-and-mortar enterprises, you may be interested to know Odoo has a very useful point of sale app. Working with other Odoo apps, point of sale data can easily flow into your inventory management, email marketing, and sales operations.


The open source version of Odoo CRM has a significant learning curve, and you’ll have to pay special attention to setting it up and implementing it to prevent headaches later. The invoicing tool is a bit more complicated than necessary (you have to create a quote, followed by an order in order to generate an invoice), and reporting options are limited. Customer support is dependent on app community members.
